I spent a decent but cold half hour at West Hartford this evening.
The main pool held a pair of shelduck and the recently formed melt water pool (just west of the small brick building near the farm) contained a vocal drake mallard and four teal. As darkness encroached the relative action began, with a peregrine heading east (in the near dark at 18:17!), flying steadily over the fields just north of the A192, it skimmed over the top of the new fire station and continued in the diection of East Hartford.
A single short-eared owl hunted along the fenceline (18:20) and two canada geese dropped into the main pool with the very lastlight (18:25). Along with sub-song from skylark, oystercatcher and pheasant calling and snipe flying about, it was a by West Hartford standards, a quality thirty minutes or so!
