Farther norththis species is found frequenting the oak trees almostexclusively, though the nest is usually in a manzanita orhazel bush. In the spring these oaks are particularlyinfested with the green caterpillars, and the Warblersnever seem to tire of devouring the pests. They leanaway over to peer under every leaf; or reach up to the CONSPICUOUSLY BLACK AND WHITE 403 twigs overhead, never missing one. Twenty of theseworms is an average meal for a Black-throated GrayWarbler, and the total for a day must reach into thehundreds. When several of these busy workers huntthrough a tree together, we may feel sure that it must beclean by the time they finish the 665. Black-throated Gray Warbler. They lean away aver to peer under every Zea/. Their common note is a sharp chip, and their songis rich and very strong during the nesting season.
