Early migration at Plainsboro Preserve, March 24th

By far the best bird of the day was a breeding plumage adult eastern/yellow Palm Warbler seen relatively close to the visitor center as the main gravel trail walks back along the south edge of the old gravel pit. The other main evidence of spring was the return of Tree Swallows. Otherwise the preserve was relatively quiet - all the migrant geese have left, leaving just a few breeding Canadas and there was one Belted Kingfisher along the shoreline. The woods were predictably quiet, mainly Dark-eyed Juncos and White-throated Sparrows, with the diversity enlivened a bit by Northern Flicker and Eastern Bluebird.

Notable also were at least two Mourning Cloaks sunning themselves along sheltered parts of the main trail.
