Brown-headed Cowbird (41)

While out this a.m. I heard/saw a male BHCO (41) singing from the top of a tree. I also enjoyed listening to a SOSP sing (in fact I'm listening to him now through my kitchen window - open even though a bit cool outside) watching the FOSP dig in the leaf litter and a BRCR climb the trunk of one of my oaks. I heard another EAPH and another KILL too. I thought I heard one "seeet" of a WTSP, but was not able to locate it to verify.
