35cm Similarly to other Brazilian jays, the Curl-crested jay has white lower parts and blue and black upper parts. It may be confused with the Plush-crested jay (Cyanocorax chrysops), but while the last presents the crest in the back of the head, the yellow iris and a blue patch around the eyes, the Curl-crested jay presents the crest on the forehead, the red iris and the head is entirely black. Whereas the Old World ravens are mostly black, as well as the crows, the Brazilan corvids are colorful and most of them have white lower parts. There are 6 species of jays in Brazil, all of them extremely beautiful. The Curl-crested jay is one of Brazilian’s noisiest jays. To make the noise ...

18cm Unlike the Red-crested Cardinal ( Paroaria coronata ) the Red-cowled Cardinal does not have a crest and the absence of black patches on the head and throat distinguishes this from the other Brazilian cardinals. This bird is endemic to the Brazilian Northeastern semi-arid region called ``Caatinga´´ where it is undoubtedly one of the most beautiful songbirds. Its beaty often costs its freedom as thousands of these birds are captured in the wild to be kept as cage birds. There is large illegal traffic of these birds throughout Brazil and even to other countries. Several specimens, and even established breeding populations have been reported considerably far from its original distrib...

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...
