Ruby Throated makes sense, they are more common in areas with good mantis populations. Here in New Mexico, the most common hummers are Black Chinned, Broad Tailed, and Rufous with the occasional Anna’s and Calliope thrown in. However, I cannot recall the last time I saw a mantis here in the East Mountains (Manzanos and Sandias east of Albuquerque) Possibly too dry, or the lizards make short work of them.
Or Ehrmantraut. He can deal with low-life Mantids.
Here on Van Isle I have lots of Anna’s, a couple of Calliopes, but that’s about it.
Several of the Anna’s overwinter here. It’s really neat to have a hummer coming up to the feeder when there is 3” of snow on the ground.
