Griggstown Preserve, October 25th and 26th

I birded Griggstown Native Grassland Preserve in Franklin Twp on the mornings of Sat and Sun the 25th and 26th. On the Saturday the weather was gray and foreboding the rain storm to come, and bird activity was fairly quiet with only a few sparrows. There were a few good hawks, however: two Sharp-shinned, Cooper's, Red-tailed and an American Kestrel.

In contrast, after the passage of the storm, the following morning was much birdier with cooperative Savannah Sparrows everywhere and the usual suspects: Swamp, Savannah, Song, White-crowned, White-throated, Field Sparrows. There was also a late Blackpoll Warbler along with Yellow-rumped, Palm Warblers and Common Yellowthroat.

Bird activity at Pole Farm (Mercer Co Park NorthWest) was much lower, with Field and Song Sparrows, a fleeting Eastern Meadowlark, and the best bird being a fly-over immature Bald Eagle. Two Northern Harriers were hunting the fields.
