Lots of birds moving in the morning, raptors and passerines. Good visitor participation with GCBO staff spending a good part of the day. Afternoon birds were very high. First Greater White-fronted Geese of the season and several flocks of white pelicans, Scissor-tailed Flycatchers, Blue Jays, and cowbirds. Many, many swallows.
