The birds were occupying a fence row with blackberry bushes. There were also brewers and red-winged blackbirds present. Birds were scoped from Spencer Rd. It wasn't clear if the birds were nesting or not, but the males were advertising. This colony could use a follow-up visit. Brian Acord and Krysta Rogers.
