Also, a VCE study of Vermont's forest birds released last year showed a marked decline (40%) in the guild they referred to as aerial insectivores, which includes most of the flycatchers, chimney swifts, and tree swallows. Presumably this decline is due to a decrease in the insect populations that these birds depend on for food. Here is the link:

Swallows have been falling off here in Middlebury.
