28-3-2017 TARCOLES RIVER COSTA RICA - BOAT BILLED HERON (Cochlearius cochlearius)

The boat-billed heron (Cochlearius cochlearius ), colloquially known as the boatbill, is an atypical member of the heron family, and was formerly placed in a monotypic family, the Cochleariidae. It lives in mangrove swamps from Mexico south to Peru and Brazil. It is a nocturnal bird, and breeds semicolonially in mangrove trees, laying two to four bluish-white eggs in a twig nest.

The boat-billed heron grows to about 54 cm (21 in) long. Adults are pale grey to white in color, with chestnut-colored abdomens and black flanks. The massive, broad, scoop-like bill, which gives rise to this species' name, is mainly black. This bird is also adorned with a crest which is thought to be used in mate attraction as it is larger in males. The sexes are similar in appearance, the main differences being that females are slightly smaller, grayer in appearance, and have shorter crests than males. Newly hatched nestlings have green-yellow skin, with their upperparts covered in gray down feathers. Their upper bill is black and they have green-yellow legs. Juveniles are darker in color than adults and lack a crest.

Boat-billed herons feed on shrimp and small fish such as Dormitator latifrons, a species of sleeper goby. They tend to forage in vegetative streams, shallow water, and lagoons. When foraging in streams, they use low-hanging branches and mangrove roots to stand over the water. In ponds they will walk slowly through the water up to 10 cm (4 in) deep or will forage near the water's edge. In order to capture prey they will lunge at fish or scoop the surface of the water with their bills which are uniquely shaped for this method of capture. Additionally, they have been observed using two different feeding techniques; standing and slowly stalking prey, or disturbing the water and chasing prey.Boat-billed herons will forage nocturnally, and have been seen leaving the roost 30 minutes after sundown to feed. It has been observed that they do not feed when a light source is present such as daylight, moonlight, or artificial light. One study hypothesized that in order to forage for food in the dark and in shallow, muddy water, their bills are sensitive to touch which helps them feel for their prey.

Boat-billed herons breed during the rainy season and have been recorded as producing two clutches during this time, laying their first clutch in February during the end of the dry season. Their clutch sizes range from two to four eggs, with more eggs being laid during the first nesting period than the second. They usually nest in colonies, but have been observed nesting solitarily. Human disturbance can lead to a decrease in reproductive success, as herons tend to avoid human contact and will abandon nests if necessary.

Boat-billed herons range from Mexico to Peru, Brazil, and northeastern Argentina. They are nonmigratory birds that tend to live in seasonal lagoons and estuaries, and nest in mangroves.

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 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.

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.

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 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)

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.
