Greetings, around noon today while daydreaming about bird migration. I noticed some birds flitting about outside my office window. I grabbed my bins and went outside and had about 20 Yellow-rumped Warblers of both races, 2 Orange-crowned Warblers, and a Cassin's Vireo. This CAVI was bright, had noticeable green edges on its secondaries and yellowish on the flanks.
Good birding!
