Blue-black Grassquit (Volatina jacarina)

This is a very small and nervous bird. Taking a close up picture of this bird proved to be difficult, even during sunny days with great light available. The male in low light it looks black, but in sunlight it glows in a metallic blue color. The female is rather drab, sporting a brown look. The male perches in fence wire and posts, then suddenly starts jumping while making its call, doing acrobatic maneuvers in mid air, all to attract nearby females.
