24cm In urban areas there is only one other species of owl about the same size of the Screech Owl, that is the Burrowing Owl ( Athene cunicularia ), but while the Burrowing Owl is a diurnal species which lives mostly in open areas and spends most of the time on the ground, the Screech Owl lives on trees and has a pair of ``ears´´. The song reminds that of the Rococo Toad ( Bufo ictericus ). The Screech Owl feeds mainly on large insects but may also take mice, frogs and lizards. The nest is built in tree holes or in artificial boxes.

11,5cm. Identification: there is no other Brazilian species like this bird, at least not in urban and disturbed areas. Formerly all the house wren populations ranging from Canada to Chile were considered as a single species, but after several studies the populations south to Mexico were renamed as the Tropical House Wren (Troglodytes musculus ). This hyperactive bird hops non-stop on the ground in search for the small invertebrates it feeds on, reminding a mouse (musculus = mouse ). It only perches to rest or to sing. Its song is very complex and melodic, like other well known members of the Troglodytidae family. It is famous for the breeding behavior, as this bird may nest in the mos...

22 cm. The upper parts are brown or grayish. The chest and belly are bright yellow. Distribution: From Texas (U.S.A) to Argentina. Has expanded its distribution, benefited from deforestation. Habitat: Forest borders, cerrado, fields and cities. Diet: Mostly flying insects that it catches in small flights from a perch. Follows fires in order to catch the escaping insects. Also eats fruits. Reproduction: The nest is made of sparse sticks and is usually placed in trees with hives or with plenty of ants in order to increase safety. The offspring, (2 or 3) are fed by the couple. Natural history: Migrates to the north in the southern winter. During this migration it may appear in...

13,5cm The most distinguishing features of this species are the yellowish-orange head and the grayish-green body. This shades of color may vary depending on the subspecies, given that this bird is distributed thoughout the tropical region South to the Amazon river and East to the Andes. There is also a curiously isolated population in the Orinoco river basin. It lives in secondary forest, forest edges and even in cities with plenty of trees. Spends most of its time in the canopy, rarely coming to the ground. This bird moves in a very typical way, climbing the branches in a fast zig-zag, up to the tip and then letting itself fall onto the base of the next branch. It feeds mainly on s...

Habitat: Grasslands and open areas, sometimes inside cities. Diet: Feeds on seeds and insects. Reproduction: The male has a very typical breeding display. Perched in a branch it flies some 50cm upwards and comes back to the branch in a loop-like movement. During this display it shows its white feathers below the wings. When it fi...

A lustração exemplifica o curso da água em nosso planeta em um clima tropical. Começando com a evaporação na medida em que as partículas recebem calor sob a incidência da luz solar, condensação e formação de nuvens quando atingem certas altitudes e suas baixas temperaturas, precipitação quando as partículas condensadas se unem e sofrem o fenômeno da gravidade, infiltração quando caem e permeiam o solo atingindo os lençóis freáticos e transpiração quando é liberada pelos organismos terrestres.
