I spent about 2.5 hours at Montrose this morning, March 19, most of that
time looking at the lake. The visibility was good and there were birds
to look at, both on the water and flying around. Except for blackbirds
and Robins, landbirds were scarce. My highlights (not a complete list):

Gadwall – ~12
American Wigeon – 5
Redhead – ~30
Lesser Scaup – ~20
Greater Scaup – 1
White-winged Scoter – ~20
Common Goldeneye – ~12
Bufflehead – ~7
Common Merganser – 1 adult male flying north
Red-breasted Merganser – ~300
Red-throated Loon – 2 flying north, both in basic type plumage
Common Loon – 1 alternate plumaged bird flying north
Horned Grebe – ~50, most on the lake but a few in the harbor
Eared Grebe – 1 alternate plumaged bird on the lake
Great Black-backed Gull – 1 first cycle
Glaucous/Iceland Gull – 1 near adult flying north

The Eared Grebe was a big surprise. I tried to turn it into something
more expected but everything about the bird said Eared Grebe. Somewhat
surprisingly it was in full alternate plumage; most of the Horned Grebes
today were still in basic plumage or transitioning into alternate
plumage. I also had a meadowlark in the Dunes that looked good for a
Western but I let it go.
