At Radnor Lake this morning I saw 2 birds traveling together along the dam
that were BW Warbler x GW Warbler hybrids. 
 

The first bird had wide golden wing bars, olive back, yellow underbelly,
BW-like eye stripe- there was not a distinctive yellow cap. I'm calling it a
1st generation female Brewster's based on photos from Sibley's guide page
428 and some online pics. 

 

The second bird I had a harder time classifying. It was more yellow all over
(back, nape, throat and underneath) with thicker gold wing bars, yellow cap,
faint black eye mask.  The Lawrence's backcross adult female in the Sibley
Guide is the closest thing I can find but the bird was overall more yellow.
I'll defer to those with more expertise. Any thoughts?
