Золотистая ласточка Tachycineta euchrysea

A graceful aerial feeder often found swooping for insects over pine woodlands or perched in tall snags. The Tree Swallow is rather similar, but has a blue-green rather than golden-green iridescence above. Also, the Tree Swallow has a less deeply forked tail and lacks the white on the side of neck that is present on the Golden Swallow. Vocalizations include a scratchy “chit-it” or “chit,” a sweet inflected “ch-yoy,” and various musical twitters.
