Nate Behl, Jimena Golcher, and I relocated the blackbird flock east of town and got great looks and pictures of the previously mentioned rusty/brewer's blackbird. The bill shape (thin and slightly decurved), rusty flanks, rusty throat, and rusty edging to tertials/wing coverts all point to this being a Rusty Blackbird.
We observed the bird in the pasture at the corner of Sweetwater Rd. and Cottonwood Drive. It is associating with a flock of Great-tailed Grackles.
Tons of Lapland Longspurs in the pastures and fields around town. We came across several flocks associating with Horned Larks throughout the day.
