I completed my early June three-morning (June 1,4,5) walking survey for singing male cerulean warblers along the Lower Trail in Blair and Huntingdon counties. This is a 16.2 mi rails-to-trails along the Frankstown Branch of the Juniata River - Williamsburg is the largest town it passes.
My first survey, in 1998, was part of Cornell's cerulean warbler atlas project and covered the northern 11 miles of the trail, which has since extended. I repeated in 2001, and in recent years over the full trail. As the below table of singing males shows, my recent counts are as high or higher than in the early years, so numbers are holding steady or even increasing. This year's tally was the highest.

This is one of PA's most accessible high-quality riparian corridors and early morning bird song is very dense. There were few mosquitoes this week, but soon there will likely be more (and then a good reason to ride a bike).
