No Lesser To Me...

They may indeed be Lesser Goldfinch (Spinus psaltria) but they are still plenty fascinating to me. This certainly isn't the first time I've seen them working the downy seeds of flowering plants on the airfield, but this was the closest!

Cassin Quite a Ruckus

So the first thing I notice other than the vocalizations of kingbirds in the area, is this Red-tailed Hawk being harassed by some smaller bird. I thought maybe it was a Northern Mockingbird, however after review of the photos I see that it is indeed not a mockingbird. It is instead being tormented by kingbird -- quite a bit of pluck for bird that's considerably smaller than the hawk! What would motivate such a persistent attack? A near-by nest? Probably.
I went on about my business until the chatter from these kingbirds piqued my curiosity. It was then that I noticed the parental activity -- back and forth, to and from and light pole on the ramp next to me. I cruised over to investigate further and guess what I discover? Sure enough two adult Cassin's Kingbirds (Tyrannus vociferans) are feeding one, possibly two chicks.
