Black-chinned Hummingbirds

Before I saw the nighthawk in my previous post, I spent some time in a friend's backyard in La Junta enjoying the Black-chinned Hummingbirds coming to his feeder (and the 30 Chimney Swifts flying over plus the up to 12 Mississippi Kites doing their graceful acrobatics).
This bright male Black-chinned Hummingbird appeared to be the top hummingbird in a few conflicts at the feeder. Black-chinned Hummingbirds are not common on the eastern plains although they have been documented nesting south of La Junta where there is a lot of pinyon-juniper habitat, their most common nesting location per surveys in the 1990's that are documented in the Colorado Breeding Bird Atlas
The velvet black of the male's chin, upper and side portions of it's throat provides nice contrast to metallic violet-purple on the lower part of it's throat. SeEtta
