A Clay-colored Sparrow continues at the Rock Creek Park Maintenance Yard (actually, the open scrub area behind the yard proper); it was seen today at about 9 am. This is a first-winter bird, well marked and readily identifiable if you can get a decent look. It has been hanging out (loosely) with some Indigo Buntings. The bird has been seen on the north side of the yard, near an area of small trees with dead/dying pokeweed underneath, and has been feeding here with the buntings, It was also seen yesterday in the middle of the area, again under pokeweed, on the big hummock of weed-covered dirt in the middle of the open area. It is not very confiding, tends to be the last to come out into the open (well after the buntings fly in). So patience is needed. This is the fifth DC record. Gail Mackiernan gail@umdd.umd.edu p.s. Yesterday an adult male Mourning Warbler was seen by one lucky birder near the little pond next to the Nature Center, at 9 am, bringing the count of warbler species recorded at the Center yesterday to 19.
