Jacana is the genus comprising the two jacanas of the Americas: the northern jacana (Jacana spinosa), and the wattled jacana (Jacana jacana). [1]
The genus Jacana was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the wattled jacana (Jacana jacana) as the type species. [2] [3]
The two species are very similar to each other: about 22 cm (8.7 in) long, with long necks and fairly long yellow bills. Adults are black and chestnut-brown, with pale yellow-green flight feathers that contrast conspicuously when a bird flies. Their legs are long and grayish, and as in all jacanas, their toes are extremely long for walking on aquatic vegetation such as lily pads. They have frontal shields (like those of coots) and wattles; differences in these are the most noticeable differences between the species. Juveniles are brown above and white below, with a buff-white stripe above the eye and a dark stripe behind it. The dark colors are somewhat darker on the juvenile wattled jacana than on the northern. [4] For the etymology and pronunciation of Jacana, see the family article.
Together the species occur in marshes in the American tropics and subtropics. The northern jacana's range meets that of the wattled jacana in western Panama. [4]
As in most other jacanas, males build the nests, incubate, and brood the chicks. Both these species are polyandrous, at least in some circumstances. Females lay separate clutches (of four eggs) for up to four mates, each of which tends his clutch alone. Females occasionally practice infanticide. [4] [5]
The boat-billed heron, colloquially known as the boatbill, is an atypical member of the heron family. It is the only member of the genus Cochlearius 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 Pacific golden plover is a migratory shorebird that breeds during summer in Alaska and Siberia. During nonbreeding season, this medium-sized plover migrates widely across the Pacific.
The double-spurred spurfowl is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. Like most spurfowls, it is restricted to Africa. It is a resident breeder in tropical west Africa, but there is a small and declining isolated population in Morocco.
The masked lapwing is a large, common and conspicuous bird native to Australia, New Zealand and New Guinea. It spends most of its time on the ground searching for food such as insects and worms, and has several distinctive calls. It is common in Australian fields and open land, and is known for its defensive swooping behaviour during the nesting season.
The yellow-wattled lapwing is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food.
The black-crowned tchagra is a bushshrike. This family of passerine birds is closely related to the true shrikes in the family Laniidae, and was once included in that group.
The garden sunbird, previously known as the olive-backed sunbird, is a species of passerine bird in the family Nectariniidae that is found in the Philippines except on the Palawan island group. It was formerly considered to be conspecific with seven other species: the ornate sunbird, Palawan sunbird, Sahul sunbird, Tukangbesi sunbird, Flores Sea sunbird, South Moluccan sunbird and the Mamberamo sunbird. It is a small, brightly coloured bird with olive-green plumage on the wings and back with a bright yellow chest. It has a long downward-curved bill it uses for taking nectar and capturing insects. It is primarily nectarivorous, but will take insects and spiders, particularly when feeding chicks.
The African grey hornbill is a member of the hornbill family of mainly tropical near-passerine birds found in the Old World. It is a widespread resident breeder in much of sub-Saharan Africa and the southwest of the Arabian Peninsula. The African grey hornbill has escaped or been deliberately released into Florida, USA, but there is no evidence that the population is breeding and may only persist due to continuing releases or escapes.
The yellow-billed oxpecker is a passerine bird in the family Buphagidae. It was previously placed in the starling and myna family, Sturnidae.
The yellow-crowned gonolek, also known as the common gonolek, is a medium-sized passerine bird in the bushshrike family. It is a common resident breeding bird in equatorial Africa from Senegal and Democratic Republic of Congo east to Ethiopia. It is a skulking bird and frequents dense undergrowth in forests and other wooded habitats. The nest is a cup structure in a bush or tree in which two eggs are laid.
The turquoise tanager is a medium-sized passerine bird in the tanager family Thraupidae. It is a resident bird from Trinidad, much of Brazil, Colombia and Venezuela south to Bolivia. It is restricted to areas with humid forest, with its primary distribution being the Amazon. It was formerly treated as being conspecific with the white-bellied tanager which is found in the Atlantic Forest of eastern Brazil.
Trogon is a genus of Coraciimorphae birds in the trogon family. Its members occur in forests and woodlands of the Americas, ranging from southeastern Arizona to northern Argentina.
The yellow bishop, also known as Cape bishop, Cape widow or yellow-rumped widow, is a resident breeding bird species in Angola, Botswana, Burundi, Cameroon, Congo, Equatorial Guinea, Eswatini, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Nigeria, Rwanda, South Africa, South Sudan, Tanzania, Uganda, Zambia and Zimbabwe.
The Cape bulbul is a member of the bulbul family of passerine birds. It is an endemic resident breeder in coastal bush, open forest, gardens and fynbos in western and southern South Africa. This species nests mainly in the southern spring from September to November. The nest is a thick-walled cup concealed by foliage in a small tree or shrub.
The little woodpecker is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in every mainland South American country except Chile, Suriname, and Uruguay.
The long-toed lapwing , also known as the long-toed plover, is a species of wading bird in the lapwing subfamily, within the family Charadriidae. It is mainly sedentary and found across central and eastern Africa, from Chad and South Sudan in the north to Mozambique in the southeast of its range. It is one of 13 species of ground-nesting lapwings found in Africa.
The Senegal batis is a species of small passerine bird in the wattle-eyes family, Platysteiridae. It occurs in western Africa where it is found in dry savanna and subtropical or tropical dry shrubland. It was originally given the binomial name Muscicapa senegalensis by Carl Linnaeus in 1766.
The Cayenne jay is a species of bird in the family Corvidae. It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical dry shrubland, and heavily degraded former forest.
The Madagascar blue vanga is a bird species in the family Vangidae. It is found in Madagascar, where its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The green-backed trogon, also known as the Amazonian white-tailed trogon, is a bird in the trogon family Trogonidae. It is widely distributed across the Amazon rainforest with a disjunct population on the southeast coast of Brazil. As with all trogons, this species is sexually dimorphic. The male has a yellow belly without a white breastband, a blue head with a pale-blue orbital eye-ring, a blue bill, a green back and a green tail that is mostly white below. The female is duller with a dark grey head, a dark grey back and some black barring beneath the tail.
