Saltador de alas verdes

Identificación

Slightly smaller than other species of the same genus, it has the same strong black beak that gave rise to the common name of these birds. As in the Saltator maximus , it has a green back, gray tail and sides of the head. The superciliary stripe is the longest of the three species (adult bird), with the "mustache" less defined and the throat all white. Underneath, gray dominates on the sides, becoming orange brown and white in the center of the belly. The wings are greenish. The juvenile does not have such a long stripe, being the same failed or nonexistent, right after leaving the nest. Some juveniles are striped below.<p>Very energetic and fortified beak (which gave the name “iron crack”), with tail differentiated in size. There are no bodily differences between males and females.<p>Its singing varies slightly from region to region, although it maintains the same timbre.

Comportamiento

Saltator similis is a typical omnivore, feeding on fruits, insects, seeds, leaves and flowers (like those of the Ypê). Enjoys the fruits of tapiá or tanheiro (Alchornea glandulosa).The male usually brings food to the female.<p>The nest, built in bushes 1 to 2 meters high, is a spacious bowl, about 12 centimeters in outer diameter, made with large dry leaves secured by some branches, resulting in a loose construction; small roots and herbs are placed inside. The 2 or 3 eggs, elongated, measure about 29 by 18 millimeters and are light blue or blue-green, with small and large spots on the blunt pole, forming a crown. During the breeding period, he lives strictly with couples, being extremely loyal to a territory.<p><p>In Brazil, Saltator similis is appreciated by its singing abilities, with different varieties being identified by their particular singing (var. "Boi" and var. "João"). Birds are captured illegally, particularly in areas of Atlantic Forest, near urban centers, where they are traded in the black market. IBAMA has been effective in curbing such practices and the number of illegal birds captured has decreased from 2000 to 2014. However, with cuts in budget, and therefore less fiscalization, the numbers can be much higher [data needed].
