About the black capped vireo • The black-capped vireo migrate to Mexico during the winter and fly back to central Texas to breed in the summer or around march or April. • They are a songbird approximately 4.5 inches long and a wingspan of 7 inches.
Habitat • Black capped vireos live in shrubby areas and in small trees. They are usually in areas of low vegetation.
Male black-capped vireos • Males have black caps and red eyes surrounded by white spectacles. Pale wing bars and a black olive color. On the underside they are white. Photo credit--Steve Maier
Female black-capped vireo • The females are similar to males but the females are duller. Instead of a black cap they have a dark gray cap on their heads. They are slightly smaller than the males
Territories • Males protect their territory from other male birds with a serious of notes followed by short pauses in between. They also advertise their territory to the females in the same way. • The male territory is about 2-4 acres and the male remain loyal to their territory throughout their lives.
Choosing a mate • The female chooses her mate. The male will display his territory and join her in flight singing or making chirp noises. He will sometimes but not often display his back or swoop in an arc above her.
Nesting • Both genders take part in making the nest the day before the eggs are born. After the eggs are born both participate in incubating the eggs and catching insects. • Incubation usually lasts from 13-17 days. More eggs are born from June to May and the female stays at the nest at night. • The young beg the adults for food and keep close to their parents.
Endangered • These lovable birds are endangered. Their habitat is either being changed or cleared out. Where they live are perfect places for livestock and is often why they are cleared out. • Brown-headed cowbirds are another reason young vireos die. The cow bird lays its eggs in the black capped vireos nest. The vireos can’t tell the difference but cowbird eggs hatch early and the vireos “adopt” the cowbird young. Since the cowbird are bigger they need more food and the vireos barely feed their own
