28-3-2017 TARCOLES RIVER COSTA RICA - BARE THROATED TIGER HERON (Tigrisoma mexicanum)

The bare-throated tiger heron (Tigrisoma mexicanum) is a wading bird of the heron family, Ardeidae, found from Mexico to northwestern Colombia, with one recorded sighting from the United States in Hidalgo County, Texas. It is 80 cm (31 in) in length and weighs 1,200 g (42 oz).

This large species is found in more open habitats than other Tigrisoma herons, such as river and lake banks. It waits often motionless for suitable prey such as fish, frogs or crabs to come within reach of its long bill.

This is a solitary breeder, not normally found in heron colonies. The nest is a small flattish stick platform in a tree into which 2–3 green-tinged white eggs are laid.

The throat is bare and is greenish-yellow to orange in all plumages. The adult has black crown and light grey sides of the head, the sides of the neck and the upperparts otherwise blackish narrowly barred buff. The median stripe down the fore-neck is white-bordered with black; the remaining underparts are dull cinnamon brown. The juvenile is buff coarsely barred with black, more mottled and vermiculated on wings; the throat, median underparts, and belly are whitish.

The flight is heavy, and the call is a hoarse howk-howk-howk. Males also give a booming hrrrowwr! call, especially at sunset. During emission of the call, the beak opens wide and undulations can be seen along the course of the throat from mid-thorax caudally.

A large but short-legged primitive-looking heron of mangroves and freshwater wetlands in tropical lowlands. Usually found in wooded areas, but also in lagoons in open wetlands. It has a bare yellow throat in all plumages (not always visible) and greenish legs. The adult has grey cheeks, finely barred plumage and rusty brown thighs. The immature has very conspicuous blackish and bright brown barring (hence the name Tiger Heron).

The rufescent tiger heron is found in wetlands from Central America through much of South America. It generally occurs below 500 m (1,600 ft), though it has been recorded as high as 1,600 m (5,200 ft) in Colombia.

28-3-2017 TARCOLES RIVER COSTA RICA - ANHINGA (FEMALE) (Anhinga anhinga)

The Anhinga, sometimes known as the snakebird, darter, American darter, or water turkey, is a distinctive water bird inhabiting the warmer parts of the Americas. Its name, derived from the Brazilian Tupi language, translates to "devil bird" or "snake bird," a nod to its serpentine swimming style where only its neck protrudes above the water's surface. The Anhinga is part of the darter family, Anhingidae, and is a close relative to its Indian, African, and Australian counterparts. It is a large bird, with a length of about 89 cm and a wingspan of 1.14 meters, and it is known for its sharp, slender beak used for spearing fish.

The male Anhinga boasts a glossy black-green plumage with wings and tail of a glossy black-blue, and a distinctive white tail tip. The back of its head and neck feature elongated feathers that are gray or light purple-white, with the upper back and wings adorned with white spots or streaks. The female, on the other hand, has a pale gray-buff to light brown head, neck, and upper chest, with a chestnut lower chest or breast and a back that is browner than the male's. Juveniles are mostly brown until their first breeding season.

Anhingas are typically found in warm, shallow waters, where they can be seen swimming with only their necks visible above the surface.

The species is widespread, with the American Anhinga divided into two subspecies: A. a. anhinga, found mainly east of the Andes, and A. a. leucogaster, located in the southern United States, Mexico, and some Caribbean islands. Migration patterns are influenced by temperature and sunlight, with birds moving towards the equator during winter.

Anhingas are adept swimmers, using their webbed feet to pursue prey underwater. They spear fish with their sharp beaks and are known for their unique drying behavior, where they spread their wings to dry their non-waterproof feathers and absorb heat, often standing in a posture that resembles a male turkey.

The Anhinga is often mistaken for the double-crested cormorant due to its size and shape. However, it can be distinguished by its longer and wider tail and sharply pointed bill, as opposed to the cormorant's shorter tail and hook-tipped bill.

Anhingas feed on a variety of aquatic prey, including fish, amphibians, invertebrates, and insects. They are skilled hunters, stalking fish underwater and spearing them with their beaks. Larger fish are repeatedly stabbed and then released, while smaller catches are brought to the surface and swallowed head-first.

The Anhinga is protected under the Migratory Bird Treaty Act of 1918 in the United States. With a vast global range and frequent occurrence, the species is classified as Least Concern by the IUCN Red List.

28-3-2017 CARARA NAT PARK, COSTA RICA - WHITE WHISKERED PUFFBIRD (Malacoptila panamensis)

The white-whiskered puffbird (Malacoptila panamensis ), also called the white-whiskered soft-wing or brown puffbird, is a near-passerine bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found from southeastern Mexico through Central America (except El Salvador), Colombia, and Ecuador into Peru.

The white-whiskered puffbird is about 18 cm (7.1 in) long with an average weight of about 43 g (1.5 oz). Unlike most puffbirds, the male and female have different plumages. Both sexes have bristles around the base of the large bill, and white "whiskers", which are actually tufts of feathers. The nominate adult male's upperparts are brown to chestnut brown. The forecrown has narrow buff or tawny streaks and most of the rest of the upperparts have buff or tawny spots. The tail is chesnut brown. Its lores, supercilium, cheeks, and the sides of the neck are tawny. The throat and upper breast are tawny to tawny buff and the rest of the underparts are buffy white with darker streaks on the breast and flanks. The adult female has less of a chesnut cast; its crown is grayer and its upperparts olive to brown. Most of the underparts are buff to cinnamon-buff with darker streaks; the abdomen is white. Juveniles are like the female but with heavier streaking on the underparts. The subspecies are all similar to the nominate, differing mainly in the shades of gray, brown, and rufous and in the density of the streaking.

1-4-2017 MIAMI, FLORIDA - RED WINGED BLACKBIRD (FEMALE) (Agelaius phoeniceus)

The Red-winged Blackbird (Agelaius phoeniceus) is a striking and abundant passerine bird, belonging to the family Icteridae. Exhibiting pronounced sexual dimorphism, the male is resplendent with glossy black plumage, accented by a vibrant red shoulder patch edged with a yellow border. The female, in contrast, is cloaked in more subdued hues of brown, adeptly blending into her surroundings.

Males are easily identified by their jet-black feathers and the scarlet and yellow "epaulets" on their wings. Females are more cryptic, with a mottled brown appearance, often with streaks or lighter undersides. Both sexes possess a pointed bill and a medium-length, rounded tail.

Red-winged Blackbirds are versatile in their choice of habitat, though they show a strong affinity for wetlands. They are commonly found in freshwater and saltwater marshes, particularly where cattails are present. They also inhabit dry upland areas such as meadows and prairies.

This species is widespread across North America, from Alaska and Newfoundland, extending south to Florida, the Gulf of Mexico, Mexico, and parts of Central America. They are also found in isolated regions of El Salvador, Honduras, and Costa Rica.

Red-winged Blackbirds are known for their territorial nature, especially during the breeding season. Males can be seen perched conspicuously, singing and displaying their shoulder patches, while females are more secretive, often foraging within dense vegetation.

The male's song is a distinctive, scratchy "oak-a-lee," while the female's vocalizations include a chattering "chit chit cheer teer teer." Their calls serve as important communication signals within their social structure.

Nesting in loose colonies, the female constructs a basket-like nest attached to marsh vegetation or shrubs. Clutches typically consist of three to four eggs, which are incubated solely by the female. Red-winged Blackbirds are polygynous, with males defending territories that may contain multiple females.

The Tricolored Blackbird (Agelaius tricolor) can be confused with the Red-winged Blackbird, but males of the former have darker red epaulets edged with white, not yellow.

An omnivorous bird, the Red-winged Blackbird's diet includes seeds, grains, insects, and small animals. They exhibit foraging flexibility, adapting their diet seasonally and based on availability.

The Red-winged Blackbird is classified as Least Concern by the IUCN. Despite its abundance, habitat destruction and changes in agricultural practices have led to population declines in some areas. However, the species' adaptability has allowed it to persist in a variety of environments.

23-3-2017 SAN GERARDO DE DOTA COSTA RICA - THICK BILLED EUPHONIA (Euphonia laniirostris)

The thick-billed euphonia (Euphonia laniirostris ) is a species of bird in the family Fringillidae, formerly placed in the Thraupidae.

Small, compact, short-tailed finch-like bird. Usually yellow below and blue-black above with a thick bill. To identify male euphonias, focus on the crown and throat: in Thick-billed, the crown is entirely yellow and the throat is also yellow. Females are extremely difficult to separate from other euphonias, especially Yellow-crowned, but are often seen in pairs or small groups with the more distinctive males. They frequent open woodland habitats, edges and gardens. They may form foraging flocks with other species such as warblers and tanagers.

This euphonia measures 10 cm (3.9 in). The male has entirely yellow underparts from throat to vent save for a small terminal patch of white on the undertail. Upperparts are a dark blue-black except for the yellow crown patch which extends from the bill over the head to just past the eye. The female, like many euphonias, is dull olive above and yellow below.

It is found in Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest.

13-4-2017 HUELVA, SPAIN - YELLOW LEGGED GULL (Larus michahellis)

The yellow-legged gull is a large gull found in Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus.The genus name is from Latin Larus which appears to have referred to a gull or other large seabird, and the species name honours the German zoologist Karl Michahelles.

The yellow-legged gull is a large gull, though the size does vary, with the smallest females being scarcely larger than a common gull and the largest males being roughly the size of a great black-backed gull. They range in length from 52 to 68 cm (20 to 27 in) in total length, from 120 to 155 cm (47 to 61 in) in wingspan and from 550 to 1,600 g (1.21 to 3.53 lb) in weight. Among standard measurements, the wing chord is 40.8 to 47.2 cm (16.1 to 18.6 in), the bill is 4.6 to 6 cm (1.8 to 2.4 in) and the tarsus is 5.6 to 7.5 cm (2.2 to 3.0 in). Adults are externally similar to herring gulls but have yellow legs. They have a grey back, slightly darker than herring gulls but lighter than lesser black-backed gulls. They are much whiter-headed in autumn, and have more extensively black wing tips with few white spots, just as lesser black-backed. They have a red spot on the bill as adults, like the entire complex. There is a red ring around the eye like in the lesser black-backed gull but unlike in the herring gull which has a dark yellow ring.

14-4-2017 GIBRALTAR - BARBARY MACAQUE (Macaca sylvanus)

The unique Barbary macaques (Macaca sylvanus) are the only primates, occurring north of the Sahara in Africa. In addition, these animals are the only macaques, found outside of Asia. As highly adaptable creatures, they are capable of surviving in various environments and temperatures from fir and mixed oak forests to sheer cliffs. Moreover, the Barbary macaques are among the few monkeys, inhabiting cold and snowy regions. They are communal foragers, looking for food both terrestrially and in trees.

The Barbary macaque has a dark pink face with a pale buff to golden brown to grey pelage and a lighter underside. The color of mature adults changes with age. In adults and subadults, the fur on the back is variegated pale and dark which is due to banding on individual hairs. In spring to early summer, as the temperatures rise, the adult macaques molt their thick winter fur. The species shows sexual dimorphism with males larger than females. The boneless vestigial tail is greatly reduced compared with other macaque species and, if not absent, measures 4-22 mm (0.16-0.87 in).

The natural range of these primates covers the Atlas Mountains of Algeria and Morocco in North Africa. The Barbary monkeys have also been introduced from Morocco to Gibraltar, where these animals currently occur in a small population. They are most commonly found in high-altitude mountains, rocky cliffs, and gorges. The ideal habitat of this species is cedar forest, although the animals often inhabit mixed forests of cedar and holm-cork oak, pure oak forests, shrubby rock outcrops along coasts as well as grasslands, found at low elevations within their range.

Barbary macaques are generally active during the daytime hours, sleeping at night in single-sex clusters of 2-3 macaques. Most of their active time is spent traveling and looking for food. The Barbary macaques are highly social animals, gathering in groups of up to 59 individuals with an average of 24. These troops contain individuals of both sexes with equal proportions. Both males and females have their separate hierarchies. Females form strictly matrilineal hierarchies, where each individual is specifically ranked. Meanwhile, the social system of males is somewhat looser. In addition, males of this species are less aggressive than females. Mutual grooming is a common activity in these primates. It's an important part of their life, which helps remove parasites and reduce stress as well as enhances interpersonal relationships between members of a group. About half of all communication between conspecifics contains aggressive behavior. However, the Barbary macaques are more peaceful animals, than most primates.

Barbary macaques have a polygynandrous (promiscuous) mating system, where individuals of both sexes have numerous mates. They breed in November-December and produce offspring in April-June. A single infant is born after a gestation period of 158-170 days. The Barbary macaques are known to practice cooperative breeding, which means that all members of the troop take care of newborn babies. Weaning occurs at about 1 year old. The age of reproductive maturity is 4.5-7 years old in males and 2.5-4 years old in females, after which the latter continue living with their natal troop, whereas the former have to disperse.

14-4-2017 GIBRALTAR - SPANISH FESTOON BUTTERFLY (Zerynthia rumina)

Zerynthia rumina, the Spanish festoon, is a butterfly belonging to the family Papilionidae. It is a widespread species in Iberia and frequents most habitats.

It is found in North Africa, the Iberian Peninsula and southern France.

Zerynthia rumina is an extremely striking species. In south east France it can be confused with the southern festoon (Zerynthia polyxena). The two can be told apart by the presence of blue on the hindwing of the southern festoon.

The Spanish festoon also has extensive red on the forewings.

The flight period is generally in April and May with the possibility of a very small second brood in September.

Its size is 40-45 mm wingspan

Prefers calcareous hillsides with low, abundant vegetation

Altitude is up to 2,200 metres

It develops in a single generation between February and June, and in coastal areas it has a second generation in autumn.

It perches in the sun on the ground and on wild flowers 

Host plant Aristolochia, A. pistolochia, A. rotunda, A. longa,  Aristolochia baetica , A. fontanesi

Although it is not in danger in most of its flight territory, there are two endemic subspecies that are close to extinction if immediate protective measures are not taken. One of them is cantabricae Gómez-Bustillo (between the southwest of Santander, Palencia and Burgos) and the other, minima Gerhandinger (El Regajal, Aranjuez-Madrid) (Source MMA)

10-4-2017 PUNTA DEL GARDO, THE AZORES - AZOREAN CHAFFINCH (Fringilla coelebs ssp. moreletti)

The Azores chaffinch (Fringilla moreletti) is a small passerine bird in the finch family Fringillidae. It is a subspecies of the common chaffinch that is endemic to the Portuguese archipelago of the Azores, part of Macaronesia in the North Atlantic Ocean. It is locally known as the tentilhão or sachão.

The head and part of the dorsum are bluish gray, with the rest of the dorsal area being greenish; the wings and tail are black and white; the throat and chest are pink. The bill is lead-colored. The paws are pinkish brown. The plumage of the females is more discreet, dominating the brown tones.

The Azores chaffinch inhabits all of the Azorean Islands and is one the most common birds in the archipelago, It can be seen from sea-level to the mountainous interior, including the highest areas of Pico.

10-4-2017 PUNTA DEL GARDO, THE AZORES - AZOREAN BULLFINCH (Pyrrhula murina)

The Azores bullfinch, or São Miguel bullfinch, known locally as the priolo, is a passerine bird belonging to the true finch family. This plump bird, with its shorter wings and longer tail, is endemic to the island of São Miguel in the Azores. It measures 15–17 cm in length and weighs around 30 grams, with males being marginally larger than females. The plumage is more subdued than its Eurasian counterpart, featuring a black cap, face, wings, and tail, with the remainder of the body in shades of grey or pale grey-brown.

Males and females are almost indistinguishable, though males may show a faint pinkish hue on the belly and flanks. The Azores bullfinch can be recognized by its melancholic, flute-like whistle, which serves as its contact call.

This bird is found primarily in native laurisilva forests at elevations of 300–800 meters above sea level, particularly in the Serra da Tronqueira range and, seasonally, around Salto do Cavalo.

The Azores bullfinch is confined to São Miguel Island in the Azores, with its presence notably absent from the western end of the island.

The species exhibits seasonal movements within its range, tracking the availability of food sources throughout the year.

10-4-2017 MIAMI, FLORIDA - SOUTHERN LEOPARD FROG (Lithobates sphenocephalus)

The southern leopard frog (Lithobates sphenocephalus or Rana sphenocephala ) is a medium sized anuran in the family Ranidae (The True Frogs). It is native to eastern North America from Kansas to New York to Florida. It is also an introduced species in some areas. This species lives in cool, clear water in the north, whereas in the south it occurs in warmer turbid and murky waters of coastal and floodplain swamps, twilight zones of caves, and abandoned mines.

This frog is up to 13 cm long. It is green or brown in color with a yellowish ridge along each side of the back. Rounded dark spots occur on the back and sides; a light spot is seen on each eardrum. The male has larger fore limbs than the female. The breeding male's vocal sacs are spherical when inflated. The call is described as a "ratchetlike trill", "chuckling croak", or a "squeaky balloon-like sound".

The larva is mottled, and the eyes are positioned on the top of the head. It grows to 7.6 cm in length before maturing. The female lays an egg mass that is "baseball-sized" when close to hatching time, and contains up to 1500 eggs.

8-11-2017 HANNINGFIELD RESERVOIR, ESSEX - BRITISH DUNNOCK (Prunella modularis ssp. occidentalis),

The dunnock (Prunella modularis) is a small passerine, or perching bird. It is the most widespread member of the accentor family.

he dunnock has a drab appearance which may have evolved to avoid predation. It is brownish underneath and has a fine-pointed bill. Adults have a grey head, and both sexes are similarly colored. Unlike any similar-sized small brown bird, dunnocks frequently flick with their wings, especially during territorial disputes or when competing for mating rights. This gives rise to one of their common names, "shufflewing".

unnocks are native to large areas of Eurasia, inhabiting much of Europe including Lebanon, northern Iran, and the Caucasus. They are partially migratory; some populations are resident while birds in northern and eastern parts of the range are migratory. Dunnocks favor habitats that include forests, woodlands, shrubs, gardens, parks, and hedgerows.

Dunnocks are active during the day typically feeding on the ground. They are usually seen alone, but sometimes, may join foraging flocks. Dunnocks are territorial, especially during the breeding season, and may engage in conflict with other birds that encroach upon their nests. Males sometimes share a territory and exhibit a strict dominance hierarchy; older birds tend to be the dominant males and first-year birds are usually sub-dominant. Female territorial ranges are almost always exclusive. However, sometimes, multiple males may cooperate to defend a single territory containing multiple females. The main call of dunnocks is a shrill, persistent 'tseep' along with a high trilling note, which betrays the bird's otherwise inconspicuous presence. The song is rapid, thin, and tinkling, a sweet warble that can be confused with that of the Eurasian wren but is shorter and weaker.

1-4-2017 MIAMI, FLORIDA - RED WINGED BLACKBIRD (MALE) (Agelaius phoeniceus)

The Red-winged Blackbird (Agelaius phoeniceus) is a striking and abundant passerine bird, belonging to the family Icteridae. Exhibiting pronounced sexual dimorphism, the male is resplendent with glossy black plumage, accented by a vibrant red shoulder patch edged with a yellow border. The female, in contrast, is cloaked in more subdued hues of brown, adeptly blending into her surroundings.

Males are easily identified by their jet-black feathers and the scarlet and yellow "epaulets" on their wings. Females are more cryptic, with a mottled brown appearance, often with streaks or lighter undersides. Both sexes possess a pointed bill and a medium-length, rounded tail.

Red-winged Blackbirds are versatile in their choice of habitat, though they show a strong affinity for wetlands. They are commonly found in freshwater and saltwater marshes, particularly where cattails are present. They also inhabit dry upland areas such as meadows and prairies.

This species is widespread across North America, from Alaska and Newfoundland, extending south to Florida, the Gulf of Mexico, Mexico, and parts of Central America. They are also found in isolated regions of El Salvador, Honduras, and Costa Rica.

1-4-2017 MIAMI, FLORIDA - SNOWY EGRET (Egretta thula)

The Snowy egret (Egretta thula ) is a small white heron. It is the American counterpart to the very similar Old World Little egret, which has become established in the Bahamas. At one time, the plumes of the snowy egret were in great demand as decorations for women's hats. They were hunted for these plumes and this reduced the population of the species to dangerously low levels. Now protected in the United States by law, under the Migratory Bird Treaty Act, this bird's population has rebounded.

Adult Snowy egrets are entirely white in color apart from the yellow lores between the long black bills and the eye, black legs, and bright yellow feet. The nape and neck bear long, shaggy plumes known as aigrettes. Immature Snowy egrets have duller, greenish legs.

Snowy egrets are native to North, Central, and South America. They are present all year round in South America, ranging as far south as Chile and Argentina. They also occur throughout the year in the West Indies, Florida, and coastal regions of North and Central America. Elsewhere, in the southern part of the United States, they are migratory, breeding in California, Nevada, Utah, Colorado, Arizona, New Mexico, Texas, Louisiana, and Mississippi. Snowy egrets live in wetlands of many types; this includes marshes, riverbanks, lakesides, pools, salt marshes, mangroves, and estuaries.

Snowy egrets are highly social and often forage in groups with gulls, terns, ibises, and other herons; they also nest in colonies. Snowy egrets are active at dawn and dusk and rest during the day. They stalk prey in shallow water, often running or shuffling their feet, flushing prey into view by swaying their heads, flicking their wings, or vibrating their bills. They may also hover, or "dip-fish" by flying with their feet just above the water surface. Snowy egrets may also stand still and wait to ambush prey, or hunt for insects stirred up by domestic animals in open fields. These birds are usually silent; during courtship displays, when threatened or defending their territory they make a harsh squawk.

Snowy egrets are monogamous, which means that both males and females have only one partner. The breeding season starts in spring. The male establishes a territory and starts building the nest in a tree, vines, or thick undergrowth. He then attracts a female with an elaborate courtship display which includes dipping up and down, bill raising, aerial displays, diving, tumbling, and calling. The female finishes the construction of the nest with materials brought by the male. It is constructed from twigs, rushes, sedges, grasses, Spanish moss, and similar materials and may be 15 in (38 cm) across. The female lays up to 6 pale bluish-green eggs which hatch after about 24 days. The young are altricial and covered with white down when first hatched. They leave the nest after about 22 days and become reproductively mature at 1 to 2 years of age.

1-4-2017 MIAMI, FLORIDA - RED BELLIED WOODPECKER (Melanerpes carolinus)

The red-bellied woodpecker (Melanerpes carolinus) is a medium-sized woodpecker of the family Picidae. It breeds mainly in the eastern United States, ranging as far south as Florida and as far north as Canada. Though it has a vivid orange-red crown and nape it is not to be confused with the red-headed woodpecker, a separate species of woodpecker in the same genus with an entirely red head and neck that sports a solid black back and white belly. The red-bellied earns its name from the pale reddish blush of its lower underside.

These birds mainly search out arthropods on tree trunks. They may also catch insects in flight. They are omnivores, eating insects, fruits, nuts and seeds. Their breeding habitat is usually deciduous forests. They nest in the decayed cavities of dead trees, old stumps, or in live trees that have softer wood such as elms, maples, or willows; both sexes assist in digging nesting cavities. Areas around nest sites are marked with drilling holes to warn others away.

Though the species is not globally threatened, it depends on large trees for nesting. In areas that are extensively deforested, the birds will sometimes utilize gardens, but for the most part they simply will not be present in any numbers.

In early May, the red-bellied woodpeckers begin breeding activities by drumming patterns, such as slow taps followed by short rapid drumming. The red-bellied woodpeckers use vocal signals to attract and communicate with potential mates. A low "grr, grr" sound is observed in a pair of woodpeckers from the start of courtship until the end of the breeding season.[12] In an intraspecific conflict, red-bellied woodpeckers usually make a loud "chee-wuck, chee-wuck, chee-wuck" sound. As indicated by Kilham 1983, the red-bellied woodpecker drums with its bill during conflict situation and taps to maintain pair bonding. An example of a conflict event would be competing for the same mate. Nevertheless, red-bellied woodpeckers are known to be in monogamous relationships. They have been known to rapidly peck on aluminum gutters of houses to produce a loud noise in order to attract females.

Woodpeckers depend on dead and drying wood for nesting purposes. The male red-bellied woodpecker takes the initiative in locating a nest hole. He will then seek approval from his mate by mutual tapping. The red-bellied woodpecker excavates holes in trees for nesting and roosting. By excavating cavities, they play an important role in forest communities for other species as well. For example, squirrels and bats use these cavities as shelter. The female red-bellied woodpecker accepts the nesting site by completing the excavation and entering the nest hole.

Researchers have documented that red-bellied woodpeckers tend to nest in clear areas with only a few trees. Studies have indicated that close canopy areas do not impact the bird's nesting behavior; however, further studies are needed and are in progress. Red-bellied woodpeckers breed once per year and are territorial during the nesting season. A pair begins nesting in April or May holding a year-round territory and showing high site fidelity.

Red-bellied woodpeckers depend on dead trees for nesting. Recent studies have shown that these woodpeckers experienced low breeding due to cutting sites of dead trees; however, predators are still of main concern. The juvenile red-bellied woodpecker is ready to fledge at 24 to 26 days of age. Natal dispersal has been observed in juvenile red-bellied woodpeckers. The juvenile red-bellied woodpecker remains in its natal area for approximately  weeks after fledging. In some cases, the woodpecker may return to its natal area for breeding, depending on predation levels and food resources.

1-4-2017 MIAMI, FLORIDA - EASTERN GRAY SQUIRREL (Sciurus carolinensis)

The Eastern gray squirrel (Sciurus carolinensis) is a tree squirrel native to eastern North America; there it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the Eastern gray squirrel in Europe, in particular, is regarded as an invasive species.

The Eastern gray squirrel is a squirrel of medium size, and both males and females are of the same size and color. Its fur is mainly black or gray, the gray color being grizzled and often banded with gray and black guard hairs, tinged white, with the underside being white. Its tail is quite bushy and sometimes reddish in color and is used for maintaining balance while it leaps between branches. The overall fur color may change with different seasons, with the grayish fur being tawnier during summer, and the tail whiter.

Eastern gray squirrels are native to the eastern and mid-western parts of America, and to the south of the eastern parts of Canada. They range from Manitoba to New Brunswick, and south to Florida and East Texas. They inhabit large areas of mature, dense woodland ecosystems. These forests usually contain large mast-producing trees such as oaks and hickories, providing ample food sources. Close to human settlements, Eastern gray squirrels are found in parks and backyards of houses within urban environments and in the farmlands of rural environments.

1-4-2017 MIAMI, FLORIDA - BLACK BELLIED PLOVER (Pluvialis squatarola)

The grey plover (Pluvialis squatarola), known as the black-bellied plover in North America, is a large cosmopolitan plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.

Their breeding habitat is Arctic islands and coastal areas across the northern coasts of Alaska, Canada, and Russia. They nest on the ground in a dry open tundra with good visibility; the nest is a shallow gravel scrape. Four eggs (sometimes only three) are laid in early June, with an incubation period of 26–27 days; the chicks fledge when 35–45 days old.

They migrate to winter in coastal areas throughout the world. In the New World they winter from southwest British Columbia and Massachusetts south to Argentina and Chile, in the western Old World from Ireland and southwestern Norway south throughout coastal Africa to South Africa, and in the eastern Old World, from southern Japan south throughout coastal southern Asia and Australia, with a few reaching New Zealand. Most of the migrants to Australia are female. It makes regular non-stop transcontinental flights over Asia, Europe, and North America, but is mostly a rare vagrant on the ground in the interior of continents, only landing occasionally if forced down by severe weather, or to feed on the coast-like shores of very large lakes such as the Great Lakes, where it is a common passage migrant.

1-4-2017 MIAMI, FLORIDA - AMERICAN WHITE IBIS (Eudocimus albus)

The American white ibis (Eudocimus albus) is a striking wader of the ibis family, Threskiornithidae. It is a medium-sized bird with a predominantly white plumage, which contrasts with its bright red-orange down-curved bill and long legs. The tips of its wings are black, a detail most apparent when the bird is in flight. Sexual dimorphism is present, with males being larger and possessing longer bills than females.

Adult American white ibises have distinctive pink facial skin and black wingtips visible in flight. In non-breeding condition, their bill and legs are a vivid red-orange. During breeding, the bill darkens at the tip and the legs take on a purple hue. Juveniles are brown and white, with the white becoming more prevalent as they mature. The species is relatively short-legged and bulky for its size, with a wingspan ranging from 90 to 105 cm.

The American white ibis frequents a variety of wetland habitats, including shallow coastal marshes, mangrove swamps, and inland wetlands such as marshes, ponds, and flooded fields. It adapts well to both natural and man-made water bodies.

This ibis is found from Virginia through the Gulf Coast of the United States, extending south through the coastal New World tropics. Its breeding range includes the Gulf and Atlantic Coasts, as well as the coasts of Mexico and Central America. The non-breeding range extends further inland and includes the Caribbean and parts of South America.

The American white ibis is a sociable bird, often seen in large flocks. It is territorial during the breeding season, with pairs forming monogamous bonds. Males may engage in extra-pair copulation to increase reproductive success. The species is known for its undulating flight pattern and honking calls.

The primary call is a honking sound, used in various contexts such as flight and courtship. Additional vocalizations include a muted foraging call and a high-pitched begging call from young in the nest.

Breeding occurs in large colonies near water, with both parents caring for the young. Nesting begins with the availability of suitable habitat, and the female is responsible for nest construction. Clutch sizes vary, with crayfish being the preferred food for chicks.

The American white ibis can be confused with the glossy ibis or the wood stork, but can be distinguished by its white plumage and red-orange bill and legs. Juveniles may be mistaken for the scarlet ibis, but the latter has darker legs.

The diet primarily consists of small aquatic prey, with crayfish being favored. The ibis probes shallow waters with its beak to locate and capture prey, which it does not visually see. Diet varies with habitat and prey availability.

The American white ibis is classified as Least Concern by the IUCN. Populations are stable, though they can fluctuate and move between states. Conservation efforts focus on preserving wetland habitats and monitoring environmental impacts such as pollution.

1-4-2017 MIAMI, FLORIDA - GREEN HERON (Butorides virescens)

The Green Heron (Butorides virescens) is a small, secretive wader, cloaked in an iridescent greenish-black cap and a rich chestnut neck. Its wings are a tapestry of grey-black that transitions into hues of green or blue. The adult's plumage is complemented by grey underparts and short yellow legs, while its bill is a dark, pointed instrument of precision. Females are generally smaller and exhibit less vibrant plumage, especially during the breeding season. Juveniles present a more muted appearance with streaked brown and white head sides, neck, and underparts, and their legs and bill bear a greenish-yellow tinge.

Adult length: Approximately 44 cm (17 inches)

Wingspan: 25.2–26.8 inches (64–68 cm)

Weight: Around 8.5 oz (240 g)

Distinguishing features include a glossy greenish-black cap, a chestnut neck with a white line down the front, and short yellow legs.

 

The Green Heron favors small wetlands nestled within low-lying areas, where it can be most often observed during the twilight hours of dusk and dawn.

This heron is native to North and Central America, with migratory populations moving between breeding and wintering grounds. It is a rare vagrant to western Europe and may occasionally stray as far as Hawaii from the Pacific coast of North America.

The Green Heron is a solitary feeder, often seen standing motionless on the shore or perched on branches, patiently awaiting its prey. It is known for its remarkable use of tools, such as dropping bait onto the water's surface to lure fish—a testament to its ingenuity.

The call of the Green Heron is a sharp and sudden "kyow," with a series of softer "kuk" calls. During courtship, males emit a variety of sounds including "raah-rahh," "whoom-whoom-whoom," and "aroo-aaroo" to attract a mate.

These herons are seasonally monogamous, with pairs forming in the breeding range after males perform elaborate courtship displays. They nest in forest and swamp patches, constructing platforms of sticks, often in shrubs or trees. Clutches typically consist of 2–6 pale green eggs, incubated by both parents.

The Green Heron can be confused with its sister species, the Striated Heron (Butorides striata), with which it was once considered conspecific under the name "green-backed heron."

The diet of the Green Heron is varied, including small fish, frogs, aquatic arthropods, and any invertebrate or vertebrate prey within its grasp. It is an opportunistic feeder, also consuming leeches, earthworms, dragonflies, damselflies, waterbugs, grasshoppers, spiders, crayfish, prawns, mice, other rodents, lizards, tadpoles, and snakes.

The Green Heron is currently listed as Least Concern by the IUCN, indicating that, at present, it does not face any immediate threat of population decline that would warrant a higher risk category.
