Given the nice habitat I continued to bird this site throughout the winter and into spring. On one trip I found a nice flock of Snipe in a wet portion of one of the fields. And twice I found rare wintering Vesper Sparrows – including 3 together on one visit. Then I found an excellent wetlands that looked great for rare migrants like Sedge Wren and Nelson’s Sparrow, and maybe even a Virginia Rail. Though on my visits I only found Swamp Sparrows. So far at least.
As the weather warmed I would typically spot good-sized flocks of Blackbirds around the fields – both Red-wings and Grackles. And often there were a few Rusty’s mixed in. I’m always hopeful for a rare Yellow-headed in with the Red-wings, so I would spend a bit of time scouring those flocks for something different. That was exactly the case on March 14 when a flock of Red-wings was feeding in the corn stubble. While watching them leapfrog across the field I spotted a pair of very glossy birds mixed in. They were roughly the size of the Red-wings so too small to be Grackles. And it was a gray day so there was no sun to enhance the irridesence of a Rusty. I quickly thought I might have a pair of male Brewer’s Blackbirds but needed better looks.
I continued to follow the flock and finally got close enough to re-spot the glossy blackbirds. They were two very glossy birds, roughly Red-wing sized, with yellow eyes. (I often say that male Brewer’s remind me of miniature Grackles.) Plus there were 2 females with them – uniform grayish-tan with dark eyes. I indeed had found a group of 2 male and 2 female Brewer’s Blackbirds. A rarity for the NC mountains, though not completely unexpected.
My statebird map for Brewer’s Blackbird is inserted below. States highlighted in blue are those where I’ve seen this species; cross-hatched states are those where Brewer’s is regular though I haven’t yet seen them. Finally, the tan-colored states of MD and NC are those where I’ve seen Brewer’s as a rarity.
Brewer’s Blackbird was number 287 for my NC statelist. And another great bird for the Rockwell Drive ag fields.
