Beau Doherty of Portland is an avid wildlife observer and excellent photographer. Below, he shares with us some photos of species you might spot during winter. Be on the lookout for them on your walks, especially those listed as endangered, threatened, or species of concern. Several of these photos were taken at the Helen Carlson Wildlife Sanctuary on South Road in Portland, a Preserve of Mattabeseck Audubon Society, designated an “eBird hotspot.“

The beautiful Hooded Merganser is seen often in winter at the Helen Carlson Preserve, in the Connecticut River, or in Great Hill Pond. This one surfaced with a small fish in its mouth. They nest in tree cavities.
