A specific clump of trees in the park area at Lake Roland seems to be attracting good numbers of warblers. Climb the hill, take the paved path to the left, and you'll find it before you get to the Pavilion. This morning, from about 8 to 9 AM, Debbie Terry and I sorted through 25-30 warblers plus other migrants within this group of perhaps 5 trees. Approximate numbers were: black-throated green (12-15); magnolia (5); parula (3); blackpoll (3); bay-breasted (1); com. yellowthroat (1); black-throated blue (1). Also, red-eyed vireo (2); peewee (1); field sparrow (1); chipping sparrow (1); ruby-crowned kinglet (1). Debbie had seen a myrtle warbler on her way into the park. We moved on to Cromwell Valley Park at about 10 AM. We heard from birders in the parking lot about Lincoln's sparrow, sapsucker, palm and myrtle warblers, but could find only the sapsucker. (Interesting that Don Burggraf, who found the sparrow, is calling it a possible Lincoln's. Our enthusiastic informants expressed no doubt!) We did, however, have a nice assortment of fall birds: blue-headed vireo, winter wren, Swainson's thrush, gray-cheeked thrush, Cooper's hawk, ovenbird. On the wooded path leading from the back of Sherwood Farm to the Field Trail, we found a group of 5 or 6 thrushes hiding in the brush; Debbie saw a Swainson's and maybe a wood thrush, then we both got great looks at the gray-cheeked. The rest of the group eluded us. A very nice morning to be birding. Peter Lev Towson, MD
