Beija-flor-de-topete (Stephanoxis lalandi, Vieillot, 1818)

Este pequeno e bonito beija-flor ocorre do Espírito Santo até o Paraguai e norte da Argentina. Como descrito pelo nome, o macho adulto apresenta um topete verde com o penacho comprido mais escuro, ventre cinza-claro com uma mancha grande azul. Aves do sul do Estado de São Paulo e para o sul apresentam topetes azuis. E verde no dorso com preto e branco nos cantos da cauda parda. Os machos jovens e as fêmeas são verdes no dorso e cinza- claros no ventre, com uma pinta branca atrás dos olhos; o bico é curto e reto. E avistado na vegetação arbustiva e nas matas ciliares dos campos de altitude ou em beiradas das matas da região Sul; aparece em áreas parcialmente des-matadas, mas desaparece de áreas com intensa agricultura. Geralmente ocorre sozinho, visitando, freqüentemente, brincos-de-princesa (Fuchsia sp.), amoras-do-campo, eucaliptos e bromélias. Durante a corte, o macho adejando ao redor da fêmea levanta o seu topete, faz barulhos com as asas (batendo 20 a 33 vezes por segundo) e emite fortes assobios, avançando e recuando no ar até que a fêmea o aceite para cópula. Grupos de 2-5 machos formam o "leque" e cantam baixos nas bordas da mata próximo a riachos para atrair as fêmeas. O ninho é em forma de pequena taça colocado em folhas terminais de varas de bambu ou em ramos de arbustos, a pouca altura, confeccionado de paina e revestido de musgos, hepáticas e líquens fixados com fios de teias de aranha. Os machos emitem forte vocali -zação ou, também, um canto longo e forte. No momento, não parece estar ameaçado de extinção, mas não é comum mesmo nos locais de ocorrência.


 

Black-breasted Plovercrest (Stephanoxis lalandi, Vieillot, 1818)

This small and beautiful hummingbird occurs from the state of Espírito Santo to Paraguay and northern Argentina. The adult male has a green crest with a long darker plume and dark belly with a big blue patch. Birds from southern São Paulo and farther south have blue crests. They have green backs and drab wings with black and white corners. The young males and females have green backs and light- gray bellies, and a white spot behind the eyes; the bill is short and straight. They are seen in shrub lands and gallery woods of montane grasslands or in the edges of woods southward; they occur in partially deforested areas but disappear in areas with intensive agriculture. Often occurring alone, they make frequent visits to fuchsias (Fuchsia sp.), mulberries, eucalyptus and bromeliads. During courtship the male flies around the female, raises its crest and makes noises with the wings (beating 20 to 33 times per second), producing piercing whistles, flying back and forth in the air until the female accepts it for mating. Groups of 2-5 males gather in loose groups or "leeks" and sing, low on the edges of woods near creeks, to attract females. The cup-shaped nest is saddled on terminal leaves of bamboo stalks or on twigs on a rather low limb and is built of plant down and covered with moss, lichen and liverwort, held together by spider webs At the moment they seem not to be endangered, but they are not common even in their natural habitats.
