From Marc Chelemer:
There was a lone Prothonotary Warbler at Great Swamp NWR in the small pond on the right side of the road after you’ve crossed the bridge if you’ve walked from the Overlook. It was sitting on low branches right over the water, flycatching. Yellow head and breast (not the orangey-yellow of a full adult male), grey wings and back, white belly. The bird did not sing. Very active. In the same area was a White-eyed Vireo dueling with a Warbling Vireo.

Also along Pleasant Plains Road in the woods just east of the Overlook, a very young (unable to fly) American Woodcock hopped across the road.

In the brushy field north and west of the intersection of Pleasant Plains and Whitebridge, way back behind the trees, the singing Yellow-breasted Chat continued.

All these birds and 43 other species were seen or heard between 7:30 and 8:45 AM this morning.
