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 - 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)

1-4-2017 MIAMI, FLORIDA - TRICOLORED HERON (Egretta tricolor)

The tricolored heron (Egretta tricolor), formerly known as the Louisiana heron, is a small species of heron native to coastal parts of the Americas. The species is more solitary than other species of heron in the Americas and eats a diet consisting mostly of small fish.

Habitat, breeding, and distribution

Tricolored herons breed in swamps and other coastal habitats and nests in colonies, often with other herons, usually on platforms of sticks in trees or shrubs. In each clutch, three to seven eggs are typically laid. The tricolored heron is the second most coastal heron in the United States.

The species' range follows the northeastern United States, south along the coast, through the Gulf of Mexico and the Caribbean, to northern South America as far south as Brazil. In the Pacific region, it ranges from Peru to California, but it is only a nonbreeding visitor to the far north.

It was likely the most numerous heron in North America until the cattle egret arrived to the continent in the 1950s. While the species' population appears to be on the decline, it remains quite common. The bird is listed as "Threatened" by the Florida Fish and Wildlife Conservation Commission.

This species measures from 56 to 76 cm (22 to 30 in) long and has a typical wingspan of 96 cm (38 in). The slightly larger male heron weighs 415 g (14.6 oz) on average, while the female averages 334 g (11.8 oz). It is a medium-large, long-legged, long-necked heron with a long, pointed, yellowish or greyish bill with a black tip. Its legs and feet are dark. The plumage of the triclolored heron changes dramatically from its juvenile form to its adult form.

Adults have a blue-grey head, neck, back, and upper wings, with a white line along the neck. The belly is white. In breeding plumage, they have long, blue, filamentous plumes on their heads and necks, and buff ones on their backs.

The tricolored heron is more solitary when foraging than other North American herons. When it forages for its prey, it is typically belly-deep in water, alone or at the edge of a mixed flock. Kent (1986) found that the diets of tricolored herons in Florida consisted of 99.7% fish and prawns. While other members of Egretta may also eat crabs and opportunistically forage for terrestrial arthropods, the tricolored heron has been consistently observed to be almost exclusively piscivorous, primarily feeding on members of Poeciliidae.

1-4-2017 MIAMI, FLORIDA - BLACK NECKED STILT (Himantopus mexicanus)

The Black-necked stilt (Himantopus mexicanus) is an American shorebird that lives in wetlands and coastlines. It is often treated as a subspecies of the Black-winged stilt, however, the American Ornithological Society (AOS) has always considered it a species in its own right.

Black-necked stilts have long pink legs and a long thin black bill. They are white below and have black wings and backs. The tail is white with some grey banding. A continuous area of black extends from the back along the hind neck to the head. There, it forms a cap covering the entire head from the top to just below eye level, with the exception of the areas surrounding the bill and a small white spot above the eye. Males have a greenish gloss to the back and wings, particularly in the breeding season. This is less pronounced or absent in females, which have a brown tinge to these areas instead. Otherwise, the sexes look alike. Downy young are light olive brown with lengthwise rows of black speckles (larger on the back) on the upperparts - essentially where adults are black - and dull white elsewhere, with some dark barring on the flanks.

Black-necked stilts occur from the coastal areas of California through much of the interior western United States and along the Gulf of Mexico as far east as Florida, then south through Central America and the Caribbean to Brazil, Peru, and the Galápagos Islands, with an isolated population, the Hawaiian stilt, in Hawaii. The northernmost populations, particularly those from inland, are migratory and spend winters from the extreme south of the United States to southern Mexico, rarely as far south as Costa Rica; on the Baja California peninsula, they are only found regularly in winter. Black-necked stilts are found in estuarine, lacustrine, salt ponds, lakeshores, alkali flats, flooded fields, and emergent wetland habitats; they usually occur in lowlands but in Central America, they can also be found in mountainous areas.

Black-necked stilts are crepuscular birds. They forage by probing and gleaning primarily in mudflats and lakeshores, but also in very shallow waters near shores. Outside of the breeding season, they are gregarious; they feed and roost in groups and migrate in large flocks. They often roost and rest in alkali flats, lake shores, and islands surrounded by shallow water. Black-necked stilts have a very interesting behavior. Since these birds live in areas with hot climates, they have to cool off the nest. To do that, parents will carry water in their ventral feathers to the nest and can make many trips a day. Fall migration of the northern birds takes place from July to September, and they return to the breeding grounds between March and May. Usually, the entire population breeding at any one site arrives, mates, incubates eggs for about a month, and protects and broods the young until they are capable of sustained flight; this population then leaves again migrating in flocks of about 15 individuals sometimes juveniles congregating in small groups and other times siblings with family groups.

1-4-2017 MIAMI, FLORIDA - TURKEY VULTURE (Cathartes aura)

10-4-2017 MIAMI, FLORIDA - SLATY SKIMMER DRAGONFLY (Libellula incesta)

Libellula incesta, the slaty skimmer, is a dragonfly of the skimmer family, native to eastern United States and southern Ontario, Quebec, and New Brunswick. Adults are 5.28 cm (2.08 in) long. Mature males are dark blue with black heads. Females and juveniles have brown abdomens with a darker stripe down their backs. Adults fly from June to August. Larvae are habitat specialists, found in the benthos of permanent lakes. 

1-4-2017 MIAMI, FLORIDA - ROYAL TERN (Thalasseus maximus)

The royal tern (Thalasseus maximus) is a tern in the family Laridae. The species is endemic to the Americas, though strays have been identified in Europe.

This is a large tern, second only to the Caspian tern but is unlikely to be confused with the carrot-billed giant, which has extensive dark under-wing patches.

The royal tern has an orange-red bill, pale grey upperparts, and white underparts. Its legs are black. In winter, the black cap becomes patchy. Juvenile royal terns are similar to non-breeding adults. Differences include juveniles having black splotched wings and a yellower bill. An adult royal tern has an average wingspan of 130 cm (51 in), for both sexes, but their wingspan can range from 125–135 cm (49–53 in). The royal tern's length ranges from 45–50 cm (18–20 in) and their weight is anywhere from 350–450 g (12–16 oz).

The calls of the royal tern are usually short, clear shrills. Some of the shrills sound like kree or tsirr; the royal tern also has a more plover-like whistle that is longer, rolling, and more melodious.

In parts of its range, the royal tern could be confused with the elegant tern, but the elegant tern has a longer, more curved, bill and shows more white on the forehead in winter.

1-4-2017 MIAMI, FLORIDA - NORTHERN CARDINAL (MALE) (Cardinalis cardinalis)

The northern cardinal (Cardinalis cardinalis), known colloquially as the redbird, common cardinal, red cardinal, or just cardinal, is a bird in the genus Cardinalis. It can be found in southeastern Canada, through the eastern United States from Maine to Minnesota to Texas, New Mexico, southern Arizona, southern California, and south through Mexico, Belize, and Guatemala. It is also an introduced species in a few locations such as Bermuda and Hawaii. Its habitat includes woodlands, gardens, shrublands, and wetlands.

The northern cardinal is a mid-sized perching songbird with a body length of 21–23 cm (8.3–9.1 in) and a crest on the top of the head. The species expresses sexual dimorphism: Females are a reddish olive color, and have a gray mask around the beak, while males are a vibrant red color, and have a black mask on the face, as well as a larger crest.

The northern cardinal is mainly granivorous, but also feeds on insects and fruit. The male behaves territorially, marking out his territory with song. During courtship, the male feeds seed to the female beak-to-beak. A clutch of three to four eggs is laid, and two to four clutches are produced each year. It was once prized as a pet, but its sale was banned in the United States by the Migratory Bird Treaty Act of 1918

 

30-3-2017 HOTEL BOUGANVILLEA,COSTA RICA - TROPICAL KINGBIRD (Tyrannus melancholicus)

The Tropical Kingbird, Tyrannus melancholicus, is a robust member of the tyrant flycatcher family. This avian species is characterized by its pale gray head adorned with a darker eye mask and an orange crown stripe. It boasts a heavy gray bill, a grayish-green back, and brown wings and forked tail. The underparts are a vibrant yellow, transitioning from a pale gray throat to an olive breast. Both sexes share a similar plumage, while juveniles can be distinguished by pale buff edges on their wing coverts.

Adults measure approximately 22 cm in length, weigh around 39 g, and have a wingspan ranging from 38 to 41 cm. Observers should look for the distinctive orange crown stripe and the bird's habit of perching openly, often high in trees.

The Tropical Kingbird favors semi-open areas with an abundance of trees and shrubs. It thrives in gardens, along roadsides, and in other areas where it can find a prominent perch to survey its domain.

This species has a broad range, breeding from southern Arizona and the lower Rio Grande Valley of Texas through Central and South America to central Argentina and eastern Peru. It is also found on Trinidad and Tobago. Birds from the extreme northern and southern parts of their breeding range migrate to warmer areas after the breeding season.

The Tropical Kingbird is known for its acrobatic flights to catch insects mid-air, a behavior known as hawking. It may also hover to glean food from vegetation. These birds are fiercely territorial, defending their space against intruders of all sizes, from frigatebirds to hawks.

The call of the Tropical Kingbird is a high-pitched, twittering trill, described as "tree-e-e-e-e-e-e." Males sing a more complex version of this call at dawn.

Pairs of Tropical Kingbirds are monogamous and often remain together throughout the year. They nest high in trees, sometimes near water, constructing a bulky nest of vines, rootlets, and twigs. The female incubates a clutch of two to four eggs for about 16 days, with the young fledging after another 18 to 19 days.

Their diet consists mainly of insects such as beetles, bees, wasps, and dragonflies. They also consume berries and fruits from various plant species, including common guava and gumbo-limbo.

The IUCN lists the Tropical Kingbird as Least Concern, with a population trend that is increasing. Estimates suggest a global breeding population of around 200 million, and the species is considered to have a low conservation concern.

30-3-2017 HOTEL BOUGANVILLEA,COSTA RICA - BALTIMORE ORIOLE (MALE) (Icterus galbula)

31-3-2017 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.

Eastern gray squirrels are aggressive, alert, and inquisitive rodents, very fast when moving and jumping amongst the treetops. These squirrels are scatter-hoarder; they hoard huge quantities of food for the future and can make several thousand caches per season. They are more active in the daytime than at night, particularly at dawn and during the afternoon. Males and females may share the same nest during the breeding season, which they build in the forks of trees, and during cold winters, squirrels may also share these dreys to stay warm. The dens are usually lined with moss plants, thistledown, dried grass, and feathers. Females nest alone during pregnancy, and lactating females are particularly aggressive and left alone by other squirrels. These squirrels do not hibernate. To communicate with each other they use both vocalizations and posturing. They have a quite varied repertoire of vocalizations, including a squeak similar to that of a mouse, a low-pitched noise, a chatter, and a raspy "mehr mehr mehr". Other methods of communication include tail-flicking and other gestures, including facial expressions. Squirrels also make an affectionate coo-purring sound that biologists call the "muk-muk" sound. This is used as a contact sound between a mother and her kits and in adulthood, by the male when he courts the female during mating season.

Eastern gray squirrels eat mostly the nuts, buds, and flowers of at least 24 types of oak trees, 10 species of hickory, beech, walnut tree species, pecans, and truffles. Corn, wheat, and other crops are eaten, particularly in the winter. In the summer insects are eaten and are probably particularly important for young squirrels.

Eastern gray squirrels have a polygynndrous (promiscuous) mating system. Males compete among themselves for the ability to mate with female eastern grey squirrels. Females may mate with more than one male as well. Breeding occurs in December-February and May-June and is slightly delayed in more northern latitudes. After a gestation period of 40-44 days, the female bears her litter of 1 to 9 (average 2 or 3) in a den or leafy nest. They are cared for in the nest by their mother until they reach independence. The young are weaned around 10 weeks, though some may wean up to 6 weeks later in the wild. They begin to leave the nest after 12 weeks, with autumn-born young often wintering with their mother. Most females begin their reproductive life at 1.25 years but can bear young as early as 5.5 months. Males usually are able to breed at 11 months.

31-3-2017 MIAMI, FLORIDA - GREEN PEAFOWL (Pavo muticus)

31-3-2017 MIAMI, FLORIDA - AMERICAN HOUSE SPARROW (FEMALE) (Passer domesticus)

The House Sparrow was introduced into Brooklyn, New York, in 1851. By 1900 it had spread to the Rocky Mountains. Two more introductions in the early 1870s, in San Francisco and Salt Lake City, aided the bird’s spread throughout the West. House Sparrows are now common across all of North America except Alaska and far northern Canada.

The House Sparrow takes frequent dust baths. It throws soil and dust over its body feathers, just as if it were bathing with water. In doing so, a sparrow may make a small depression in the ground, and sometimes defends this spot against other sparrows.

The House Sparrow prefers to nest in manmade structures such as eaves or walls of buildings, street lights, and nest boxes instead of in natural nest sites such as holes in trees.

1-4-2017 MIAMI, FLORIDA - FLORIDA SCRUB JAY ((Aphelocoma coerulescens)

The Florida scrub jay (Aphelocoma coerulescens) is one of the species of scrub jay native to North America. It is the only species of bird endemic to the U.S. state of Florida and one of only 15 species endemic to the continental United States. Because of this, it is keenly sought by birders. It is known to have been present in Florida as a distinct species for at least 2 million years, and is possibly derived from the ancestors of Woodhouse's scrub jay.

It measures 23 to 28 cm (9.1 to 11.0 in) in length, and weighs from 66 to 92 g (2.3 to 3.2 oz), with an average 80.2 g (2.83 oz). The wingspan of the jay is 33–36 cm (13–14 in). It has a strong black bill, blue head and nape without a crest, a whitish forehead and supercilium, blue bib, blue wings, grayish underparts, gray back, long blue tail, black legs and feet.

 

1-4-2017 MIAMI, FLORIDA - LIMPKIN (Aramus guarauna)

The limpkin (Aramus guarauna), also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina, but has been spotted as far north as Wisconsin. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks.

The limpkin occurs from peninsular Florida (and the Okefenokee Swamp in southern Georgia) and southern Mexico through the Caribbean and Central America to northern Argentina. In South America, it occurs widely east of the Andes; west of them its range extends only to the Equator.

It inhabits freshwater marshes and swamps, often with tall reeds, as well as mangroves. In the Caribbean, it also inhabits dry brushland. In Mexico and northern Central America, it occurs at altitudes up to 1,500 m (4,900 ft). In Florida, the distribution of apple snails is the best predictor of where limpkins can be found.

The limpkin undertakes some localized migrations, although the extent of these is not fully understood. In some parts in the northern part of the range, females (and a few males) leave the breeding areas at the end of summer, returning at the end of winter. In Brazil, birds breeding in some seasonal marshes leave during the dry season and return again with the rains. Birds may also migrate between Florida and Cuba, as several limpkins on the Florida Keys and Dry Tortugas have been reported, but these records may also represent vagrants or postbreeding dispersal. One study in Florida using wing tags found limpkins dispersed up to 325 km (202 mi) away from the breeding site. This tendency may explain vagrant limpkins seen in other parts of the United States and at sea near the Bahamas. 

1-4-2017 MIAMI, FLORIDA - WHITE CROWNED PIGEON (Patagioenas leucocephala)

The white-crowned pigeon (Patagioenas leucocephala) is a fruit and seed-eating species of bird in the dove and pigeon family Columbidae. It is found primarily in the Caribbean.

John James Audubon painted these pigeons, including the watercolour painting in his work, Birds of America, published in the early 19th century.

It is a resident breeder mainly in the Bahamas, Cuba, Jamaica and Antigua. It breeds in smaller numbers in Hispaniola (the Dominican Republic and Haiti), Puerto Rico, the Virgin Islands, the Cayman Islands, Anguilla and other Caribbean islands. It also breeds along the Caribbean coast of Central America. In the United States, it is found only in the Florida Keys, Everglades, and the southern tip of mainland Florida. They will often spend the winter in the Caribbean islands.

The white-crowned pigeon primarily lives and breeds in nest colonies or individually in low lying, coastal, mangrove forests, and will travel inland to feed on the fruits and seeds of a wide variety of plants. In Florida, the white-crowned pigeon has historically been documented nesting exclusively on remote, tidally inundated mangrove islands in wildlife refuges. Recent observations have confirmed nesting on the southern tip of mainland Florida.

With few exceptions, this species requires isolated offshore mangrove islets with limited disturbance for breeding. These tidally inundated mangrove islands which provide some protection from predators such as raccoons. However, several instances of white-crowned pigeons nesting in heavily-trafficked, urban areas, such as downtown Key West and Miami Florida, have recently been observed. This could be due to habitat loss as a result of hurricanes, and/or increased predation pressure in their historic nesting habitat. 

1-4-2017 MIAMI, FLORIDA - RED SHOULDERED HAWK (Buteo lineatus)

The red-shouldered hawk (Buteo lineatus) is a medium-sized buteo. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation.

Phyllogomphoides stigmatus, the four-striped leaftail, is a species of clubtail in the dragonfly family Gomphidae. It is found in Central America and North America.

The IUCN conservation status of Phyllogomphoides stigmatus is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.

31-3-2017 MIAMI, FLORIDA - HALLOWEEN PENNANT DRAGONFLY (Celithemis eponina)

The Halloween pennant (Celithemis eponina) is a species of dragonfly in the family Libellulidae. It is native to eastern North America, as well as the West Indies.

The Halloween pennant's wings are entirely orange-yellow in color with dark brown bands, the Halloween inspiration for its common name. Dragonflies of its genus perch at the tips of plants, waving in the breeze like pennants. The young has yellow markings, including a stripe on its back. The adult male and female may develop pale red markings, especially on the face. This species is about 38 to 42 millimetres long. It is orange.

This species occurs in eastern North America. In the southern part of its range of The Bahamas and Cuba, it is in season all year round. In northern latitudes it can be seen from mid-June to mid-August. It ranges as far north as southern Canada and as far west as the United States east of the Rocky Mountains, in New Mexico and Colorado. It lives in wet habitat types such as ponds, marshes and lakes, where it perches on vegetation.

The female lays eggs in the morning on open water with the male still attached at the head. This method is known as exophytic egg laying. Sexual activity normally occurs between 8:00 and 10:30 am. Males rest on vegetation to await the females' arrival. They usually rest upon the leaves of the American Holly Bush which help to stimulate arousal encouraging the males to develop erections.[citation needed] This species is not territorial.

The Halloween pennant enjoys perching on top of taller plants, and if they find the plant adequate, they will most commonly return many times.

The Halloween pennant feeds on other insects. It is able to fly in rain and strong wind. On hot days, it will often shade its thorax using its wings.
