The Yellow-throated Warbler is confined mostly to riverine forests, particularly in southeastern Kansas. It prefers tall sycamores for nesting and foraging.
This bird seems to be a regular nester at Schermerhorn Park, Cherokee County. In the summer months, they have also been found around Neosho Falls, Woodson County. They may also breed in Linn, Leavenworth, and Woodson counties, but no nests have been found.
Their nests are made out of thin grasses, small fine pieces of bark, lichen, moss from overhanging rocky ledges, and tent caterpillar webbing. These birds feed primarily on insects.
