[EBB Sightings] Hayward Shoreline - Winton Ave Fennel

There were many Winton Ave birders out this morning screening ever bird
that moved.
To many names to list here.
Of interest to me were the  Yellow Warblers present near the gate area off
the pave parking lot.
Using the Peterson Field Guide - for Warbler's and Sibley's to sort out the
subspecies group plumage .
1. first fall female - aestiva    (peterson's)
2. first fall female- amnicola  (peterson's)
3. first fall female - no subspecies noted,  the brownish plumage
(sibley's) whitish edges on tertials.
