There was no shortage of warblers during my recent Songbirds of Pelee Workshop. There were times when it was hard to choose which species to follow; a great problem to have!
The Tennessee warbler specializes in eating the spruce budworm. Consequently, its population goes up and down with fluctuations in the population of the budworm.
