Lee and I spent the evening at Pickering Creek, from 5:30 to 7:00.  We heard 'beenting' woodcock starting at 6:30 and saw two flights against the twilight sky.  The birds were in the unmowed area between the parking lot and the observation platform.  Other nice evening views were 13 tundra swans taking off directly overhead heading north, 8+ wood ducks coming into the pond to roost, and several bats hunting along the woods edge and drinking from the pond.
