I couldn’t make it down to De Forest Park on Friday for the Yellow-green Vireo due to prior obligations but I was there first thing Saturday morning…with about 30 other birders. After 4 hours of not seeing anything other than Warbling Vireos, Orange-crowned’s and Yellow Warblers I gave up and headed home.
Sunday I decided to check Galileo Hills to try and catch any early fall passerines. It was relatively slow with a limited number of Warblers: Orange-crowned (3), Yellow (25+), MacGillivray’s (1), Northern Waterthrush (3+). Passerine migration is certainly starting with FOS Ruby-crowned Kinglet (3), Willow Flycatcher (6) and one Cassin’s Vireo (1).
