29 Pintails (including 6 females) were foraging with Mallard/Black ducks at the Mallets Bay Causeway in Colchester. Not too far from where the causeway emerges from the trees and has water on both sides.
1 American Widgeon (male) was with them as well.
Later at Delta Park I watched 25 Pintails, but I think it was the same group. The first group had flushed and headed south when I was returning from out on the Causeway.
All and all a good look at lots of different species of waterfowl out on the Causeway. Calm water, and warm clothing made for a pleasant trek.
