BLACK-CHINNED HUMMINGBIRD.

429. Archilochus alexandri. 3½ inches.

This is similar in size and appearance to the “Ruby-Throat,” but has the chin and upper throat black, the rest of the throat being violet or amethyst, as seen in different lights. It is a very common bird in the southern part of its range. It nests low, rarely above ten feet from the ground. Nest made of plant fiber, not covered with lichens, but resembles a small piece of sponge.
