Violet-green swallow

The violet-green swallow (''Tachycineta thalassina'') is a small North American passerine bird in the swallow family. These aerial insectivores are distributed along the west coast from Alaska to Mexico, extending as far east as Montana and Texas. With an appearance very similar to the tree swallow, these individuals can be identified by the white rump side-patches that appear to separate their green back and purple tail. Violet-green swallows are secondary cavity nesters, found in a number of habitats including deciduous and coniferous forests. In addition to nesting in tree holes within these habitats, they are also widely observed nesting in the cracks of large cliffs.〔
==Description==

The distinct body form of swallows distinguishes them from other passerine birds. Their long pointed wings and slim, streamlined body evolved to catch insects while in flight. The body of the violet-green swallow is no exception. With an average body length of 5¼ in. (13 cm), the violet-green swallow is slightly shorter and appears more compact in flight compared to other members of the Hirundinidae family. The violet-green swallow most closely resembles the North American tree swallow, but can be distinguished by its shorter wings and colouration.〔Brown, C. R., A. M. Knott and E. J. Damrose. 2011.
