After spending the past few weeks birding Middlesex County, partly in connection with the Middlesex County big day run I did with Patrick, Anthony, and Tom, partly my usual patch birding, and partly for NJ Audubon's Lower Raritan Bird Survey, I felt that I wanted to take a break and go someplace different. One place that looked inviting was Watchung Reservation in Union County. I had been there frequently as a kid but only once, several years ago, as an adult. It is mentioned in Bill Boyle's Guide to Bird Finding in New Jersey, but judging from the eBird data, it appears to be somewhat underbirded for a site in such a densely-populated area.
one of my favorite bird songs. I heard more warblers, too: Black-throated Blue, Blackburnian, and Yellow Warblers. I took a trail that followed Blue Brook south towards the Deserted Village. Along this trail I heard Eastern Wood-Pewees and a Worm-eating Warbler.
