Birds that have spent the winter in the southern states are beginning to show up, some in big numbers like the large groups of blackbirds that visit your backyard-feeding stations; and migrant waterfowl such as Common Mergansers on the lakes. This is also the last month to look at huge Snow Geese flocks – areas around Prime Hook NWR (especially Broadkill Beach Road) and Bombay Hook NWR (especially at sunset over Raymond or Shearness Pools). By the end of the month, swallows, Eastern Phoebes and Ospreys have all arrived and the first of Pine Warblers show up. Woodcocks are now displaying on warmer evenings and John Heinz NWR “Tinicum” is a great place to witness this.

This is a great place to go for early spring migrants, such as American Woodcock, Tundra Swan and Ross’s Goose, and amongst the blackbirds there is always a chance of a Yellow-headed or Brewer’s. There is also a small resident flock of Sandhill Cranes. Bald Eagle nests are plentiful. By the end of the month, Osprey and Blue-winged Teal begin to arrive, and there is even the possibility of an early Ruff.
