The Resourceful Black-capped Vireo

From U.S. Fish & Wildlife Service Southwest Region:

Did you know that the black-capped vireo uses silk strands from spider webs to hold its nest together? It's true, spider silk is sticky and strong enough to bind the twigs, leaves and other materials into a nest and home for the black-capped vireo to lay eggs and rear young.
