Vireo reports


With all due respect to those posting: Regarding these reports of multiple Cassin’s Vireos from multiple locations , please note that over many decades now a typical arrival
Date for Cassins Vireo in SF is around the first days of April. A few exceptionally early birds have been noted by the third week of March.

Cassin’s vireos winter in Mexico. There’s typically a pulse of migrants noted in SoCal before we start seeing them up here.

Good birding,

Hi all, 2 Cassin's vireos (1 seen, 2 heard) on Oak Woodlands on the wooden box steps leading to Stanyan and Fulton.

Good birding.
