This warbler is the most difficult to find of the western migrant warblers. It skulks along, often on the ground, scratching at the leaf litter like a towhee. The MacGillivray’s shown is a probably a female. The males, at this time of the year are brighter with more contrast and a black margin between the yellow breast and gray throat.
This near-adult male Blue Grosbeak is another FOS bird. I toyed with the idea that it was an Indigo Bunting, a way cooler bird. But alas! I also found a female Blue Grosbeak in the same spot at bit later.
The Black-headed Grosbeak is a local breeding species. They are common in much of the county during summer and during migration in the spring and fall.
These attractive buntings breed in the Cuyamacas and can often be found during the summer in the brush around the State campground.
