I spent a little time watching and shooting the BGGN nest this past Saturday. Here are a few notes: -Nest is in action. I believe there are likely eggs in the nest. Not yet hatched. One parent will stay on the nest continuously. Every 5-10 minutes the other parent would come by and give a few quick, low call notes. The parent on the nest will reply with a similar vocalization most, but not every time, and then leave to where the other parent is calling in nearby branch or tree. The new parent then takes its place on the eggs. The nest never stayed open for more than 45 seconds. Cowbirds were definitely in the area and I believe are probably aware of the nest. Migrant songbirds were everywhere. Here is a quick list of birds I had in the parking lot or at the nest. TEWA OVBI REVI BLWA COBI GCFL PEWE SWTH NOWA LOWA SCTA.
If I make it back there this weekend, there is a good chance I could see feeding of the chicks.
