25-3-2017 TUIS CARTAGO, COSTA RICA - BRONZED COWBIRD (Molothrus aeneus)

The bronzed cowbird (once known as the red-eyed cowbird, Molothrus aeneus ) is a small icterid.

They breed from the U.S. states of California, Arizona, New Mexico, Texas, and Louisiana south through Central America to Panama. They tend to be found in farmland, brush, and feedlots. Outside the breeding season, they are found in very open habitats, and roost in thick woods. These birds forage in open areas, often near cattle in pastures. Their diet mostly consists of seeds and insects, along with snails during breeding season for a calcium source.There are three subspecies:

M. a. loyei Parkes & Blake, 1965 is found in the southwestern United States and northwestern Mexico.

M. a. assimilis (Nelson, 1900) is found in southwestern Mexico.

M. a. aeneus (Wagler, 1829), the nominate subspecies, is found in South Texas and from eastern Mexico to central Panama

The bronze-brown cowbird, which is restricted to the Caribbean coast of Colombia, was formerly considered to be an isolated population of this species.

The male bronzed cowbird is 20 cm (7.9 in) long and weighs 68 g (2.4 oz), with green-bronze, gloss-black plumage. His eyes are red in breeding season and brown otherwise. The female is 18.5 cm (7.3 in) long and weighs 56 g (2.0 oz). She is a dull black with a brown underbelly, and has brown eyes. Young birds have coloring similar to the females, with the exception of grey feather fringes.

Like all cowbirds, this bird is an obligate brood parasite; it lays its eggs in the nests of other birds. The young cowbird is fed by the host parents at the expense of their own young. Hosts include Prevost's ground-sparrows and white-naped brush finches. They develop rapidly, leaving the nest after 10–12 days.

25-3-2017 TUIS CARTAGO, COSTA RICA - ATTA LEAFCUTTER ANT (Genus Atta)

Atta is a genus of New World ants of the subfamily Myrmicinae. It contains at least 17 known species.

Atta leafcutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs. The three main castes within a nest are the queen, worker, and soldier. Only the queens and males have wings (alate), and these ants are also known as reproductives or swarmers. Although most of the ants in the nest are female, only the queens produce eggs. Queens are usually over 20 millimetres (25⁄32 in) long.

Ants of the genus Atta are leafcutter ants that comprise one of the two genera of leafcutting ants within the tribe Attini, along with Acromyrmex. They have no sting, thus inject no venom, although they are known as strong biters.

Atta spp. exhibit a high degree of polymorphism, with four castes being present in established colonies: minims (or garden ants), minors, mediae, and majors (also called soldiers or dinergates).[citation needed] Their immature development undergoes four larval stages, regardless of the ultimate caste, wherein larvae are also associated with fungal hyphae.

25-3-2017 TUIS CARTAGO, COSTA RICA - SUN BITTERN (Eurypyga helias)

The sunbittern (Eurypyga helias) is a bittern-like bird of tropical regions of the Americas, and the sole member of the family Eurypygidae (sometimes spelled Eurypigidae) and genus Eurypyga. It is found in Central and South America, and has three subspecies. The sunbittern shows both morphological and molecular similarities with the kagu (Rhynochetos jubatus) of New Caledonia, indicating a Gondwanan origin, both species being placed in the clade Eurypygiformes.

The sunbittern's range extends from Guatemala to Brazil. The nominate race, E. h. helias, is found east of the Andes in lowland tropical South America, from the Orinoco basin, through the Amazon basin and Pantanal. The subspecies E. h. meridionalis, has a more restricted distribution, being found along the East Andean slope in south-central Peru, in the lower subtropical zone at altitudes of 800–1,830 m (2,620–6,000 ft). The final subspecies, E. h. major, is found at various altitudes ranging from southern Guatemala, through Central America and the Chocó to western Ecuador. This subspecies may also be present in southern Mexico. It has been traditionally reported from the Atlantic slope of Chiapas, but no specimens are known and there have been no recent records.

The species is found in the humid Neotropical forests, generally with an open understorey and near rivers, streams, ponds or lagoons.

25-3-2017 TUIS CARTAGO, COSTA RICA - GREAT KISKADEE (Pitangus sulphuratus)

The great kiskadee, Pitangus sulphuratus, is a vibrant and robust member of the tyrant flycatcher family, Tyrannidae. It is the sole representative of its genus, easily recognized by its size, which ranges from 25 to 28 cm in length, and its weight between 53 to 71.5 grams. The species exhibits a striking head pattern with a black crown, a bold white supercilium, and a hidden yellow crown stripe. The upperparts are a warm brown, while the wings and tail display rufous fringes. Its bill is notably short, thick, and black.

To identify the great kiskadee, look for the distinctive head pattern, the strong white supercilium, and the concealed yellow crown stripe. The brown upperparts, rufous fringes on the wings and tail, and the stout black bill are key characteristics. It can be distinguished from the similar boat-billed flycatcher by the latter's more massive bill and olive-brown back.

The great kiskadee is quite adaptable, inhabiting open woodlands with tall trees, areas of human habitation, and even urban environments. It thrives in a variety of settings, from grasslands to cultivated lands.

This species has a broad range, found from the Lower Rio Grande Valley in southern Texas through Central America, and down to southern Argentina. It has been introduced to Bermuda and Tobago, where it has established populations.

25-3-2017 TUIS CARTAGO, COSTA RICA - RED BILLED PIGEON (Patagioenas flavirostris)

The Red-billed Pigeon, Patagioenas flavirostris, is a robust bird, cloaked in slate-gray plumage. Its head and neck shimmer with a maroon hue, sometimes perceived as purple, while the wing coverts share this rich coloration. The species is characterized by pale red eyes encircled by an orange ring and a distinctive red bill tipped with yellow. Unlike its relatives, this pigeon lacks the iridescent collar plumage, setting it apart visually. A blue-gray underbelly and tail coverts, along with a less brown back, provide further distinction from similar species.

Adults are identified by their dark gray bodies, maroon to purple head and neck, and the red bill with a yellow tip. Females may appear slightly duller than males, while juveniles present a more subdued color palette with dusky shoulders and a brownish mantle and wings. The species ranges in size from 30 to 37 cm in length, weighing between 230 and 425 grams.

The Red-billed Pigeon favors dry forests and is often found along riverside wetlands, thriving in these habitats throughout coastal Mexico and Central America.

This pigeon's breeding range spans from southern Texas to Costa Rica. It is prevalent in coastal and lowland areas, particularly in the Rio Grande region. Sightings in Southern Texas are less frequent, and the bird is considered rare during the winter months.

26-3-2017 RANCHO NATURALISTA - GREEN BREASTED MANGO (Anthracothorax prevostii)

26-3-2017 RANCHO NATURALISTA - BUFF THROATED SALTATOR (Saltator maximus)

This is a species of dense vegetation. The buff-throated saltator feeds on fruit (e.g. of Cymbopetalum mayanum (Annonaceae), Trophis racemosa (Moraceae), and gumbo-limbo (Bursera simaruba)), buds, nectar and slow-moving insects. It forages at low and mid levels, sometimes with mixed species flocks.

The two pale blue eggs per clutch measure some 22–32 mm (0.87–1.26 in) long by about 16.5–21.5 mm (0.65–0.85 in) wide and weigh about 4.8–6.1 g (0.17–0.22 oz) each, which is large among Saltator eggs. They are laid in a bulky cup nest up to 2 m (6.6 ft) high in a tree or bush.

26-3-2017 CATIE CENTER, COSTA RICA - GREAT TAILED GRACKLE (FEMALE) (Quiscalus mexicanus)

26-3-2017 CATIE CENTER, COSTA RICA - ANHINGA (MALE) (Anhinga anhinga)

The anhinga (Anhinga anhinga) is a water bird related to cormorants and pelicans. The word anhinga comes from the Brazilian Tupi language and means "devil bird" or "snake bird". Anhingas are skillful swimmers with unique characteristics that help them when hunting for fish. Their feathers provide less buoyancy than ducks, so they are able to dive under the water, and swim with just their thin necks above the water, earning them the nickname of the "snake bird".

The anhinga is a large bird. Its bill is relatively long (about twice the length of the head), sharply pointed, and yellow, and the webbed feet are yellow as well. The male is a glossy black-green with the wings, base of wings, and tail a glossy black-blue. The tip of the tail is white. The back of the head and the neck have elongated feathers that have been described as gray or light purple-white. The upper back of the body and wings is spotted or streaked with white. The female anhinga is similar to the male except that it has a pale gray-buff or light brown head, neck, and upper chest. The lower chest or breast is a chestnut color, and the back is browner than that of the male. The hatchling starts out bald but gains tan down within a few days of hatching. Within two weeks the tan down is replaced by white down. Three weeks after hatching, the first juvenile feathers appear. Juveniles are mostly brown until they first breed usually after the second or third winter.

Anhingas live all year round in southwest coastal areas of the United States, from North Carolina to Texas. They are also found in Central America, Mexico, Panama, and Cuba, and in South America from Colombia to Ecuador, and in the east of the Andes to Argentina. Only birds that live in the extreme north and south of their range migrate and do so based on temperature and available sunlight. Anhingas will migrate towards the equator during winter but this range is "determined by the amount of sunshine to warm the chilled birds". Although not in their usual range, anhingas have been found as far north as the states of Pennsylvania and Wisconsin in the United States. Anhingas live in tropical and subtropical areas. They prefer warm shallow waters that are fresh or brackish and can sometimes be found on coasts. They live near lakes, rivers, marshes, and mangrove swamps with tall trees and thick vegetation, and in shallow lagoons and bays.

26-3-2017 CATIE CENTER, COSTA RICA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)

The Cattle Egret, a member of the heron family Ardeidae, is a small white bird recognized for its association with grazing animals. It exhibits a stout build, with a wingspan ranging from 88 to 96 cm, and a body length between 46 to 56 cm. The species is relatively light, weighing between 270 to 512 grams. It is characterized by a short, thick neck, a robust bill, and a somewhat hunched posture.

Outside the breeding season, the adult Cattle Egret has predominantly white plumage, a yellow bill, and greyish-yellow legs. Come breeding time, the western variety develops striking orange-buff plumes on the back, breast, and crown, while the bill, legs, and irises turn a vivid red. The eastern variety differs slightly with buff coloration extending to the cheeks and throat during breeding, and the plumes taking on a more golden hue. Both sexes are similar in appearance, though males are marginally larger with longer breeding plumes.

Cattle Egrets are adaptable birds that exploit a variety of drier and open habitats more than other heron species. Their preferred environments include seasonally inundated grasslands, pastures, farmlands, wetlands, and rice paddies.

Originally native to parts of Asia, Africa, and Europe, the Cattle Egret has seen a significant expansion in its distribution, colonizing much of the rest of the world over the last century. It is now found in the tropics, subtropics, and warm-temperate zones globally.

26-3-2017 RANCHO NATURALISTA - PALM TANAGER (Thraupis palmarum)

The palm tanager (Thraupis palmarum ) is a medium-sized passerine bird. This tanager is a resident breeder from Nicaragua south to Bolivia, Paraguay and southern Brazil. It also breeds on Trinidad and, since 1962, on Tobago. In Trinidad and Tobago, it is known by colloquial names such as the "palmiste" on American Spanish countries (Colombian pronn: "pūlmist "), Brazil Pipira-verde (Portuguese pronn: "pəəpəərā-værd ") and the "green jean" in American English.

Adult palm tanagers are 19 cm (7.5 in) long and weigh 36 g (1.3 oz). They are grey to dull olive-green. The flight feathers are blackish, and the long tail is blackish edged with green. A yellow wingbar shows in flight. Sexes are similar, although females may be somewhat paler.

It occurs in semi-open areas including cultivation and gardens. The bulky cup nest is built in a tree, usually a palm, or under the eaves of a house, and the female incubates three, sometimes two, brown-blotched cream eggs for 14 days, with another 17 days to fledging.

Palm tanagers are social, restless but unwary birds which eat a wide variety of small fruit. They also regularly take some nectar and insects, including caterpillars. The song is fast and squeaky.

26-3-2017 CATIE CENTER, COSTA RICA - LEAF FOOTED BUG (Leptoscelis tricolor)

To date (2012) L. tricolor is known in Costa Rica, Panama, Colombia, Brazil, French Guiana, Guyana and Suriname. Like the other species of the genus present on the farm, they have a specific relationship with the plants of the order Zingiberales (heliconias, platanillas and related plants).

Females lay eggs individually and may spread their eggs among several different heliconia plants. Nymphs complete five instars on a single host plant. Both nymphs and adults feed on developing fruits, nectar from flowers, and phloem from inflorescences.

The generation time of Leptoscelis tricolor is approximately 30 days. The eggs hatch after approximately 14 days. First instar nymphs do not feed, but require access to water. This first instar is approximately two days, with the remaining nymphal instars five to ten days long. The cuticle of new adults remains soft for at least two days after hatching and reproductive maturity can occur within ten days. Adults can live up to 80 days or more.
