We had a great time photographing the Prothonotary warblers during my Songbirds of Pelee workshop; this one brought its dinner to show off at the minimum focusing distance of my lens.
Prothonotary warblers eat adult insects and larvae (primarily aquatic insects), ants, caterpillars, mayflies, beetles, and other insects, as well as snails and other small mollusks, spiders, and some seeds.
