Subject: [southbaybirds] Possible Hybrid Warbler
A few minutes ago I saw what looked like a good candidate for Yellow-rumped x Townsend’s Warbler hybrid at Vasona, 37.24322° N, 121.96772° W

At first glance it looked like an Audubon’s but it had a stronger face pattern with a noticeable yellowish supercilium and some yellow on the breast
