Highlights from November 1 Bird Walk to South Platte Park

Ring-necked Duck (c) Mick Thompson

A great morning down along the South Platte, where ten of us tallied 40 species (see list below). Highlights included eleven species of ducks. We started the day with the good fortune of seeing a single Surf Scoter on South Platte Reservoir, and ended the morning with six glorious Wood Ducks. Except for the Shovelers, all the other species looked to already be in prime breeding plumage – quite spectacular!

And, here’s the good news, the duck show is going to continue to get more spectacular as we head on into winter. There are still several wintering species that haven’t shown up yet, or at least not in great numbers. The Aythya genus (all divers) includes Canvasback, Redhead, Ring-necked Duck, Greater Scaup, and Lesser Scaup. We had a single male Ring-necked Duck, just to remind us what a neat group this is, and we didn’t see any of the others. BUT, we will in short order as their numbers increase locally. Another fun genus of wintering ducks is the Bucephala (from ancient Greek “ox-head”) which includes Common Goldeneye, Barrow’s Goldeneye, and Bufflehead. We had plenty of Buffleheads on Wednesday, but no Goldeneyes yet.

Northern Shrike (c) Mick Thompson

We had two other species that have just recently arrived in the area, and which I hadn’t seen since last winter – both are very handsome and always appreciated: Northern Shrike and American Tree Sparrow. The Northern Shrike breeds in the taiga (boreal coniferous forest) and taiga-tundra ecotone of the Northern Hemisphere. In the Nearctic (New World) they tend to winter sparingly as far south as northern Colorado. However, every 3-6 winters they tend to exhibit an irruptive behavior that can take them as far south as Arizona and New Mexico.

American Tree Sparrow (c) Bill Schmoker

The American Tree Sparrow has an unfortunate misnomer based on its superficial resemblance to the Eurasian Tree Sparrow. Our Tree Sparrow actually breeds primarily in the shrubs, small conifers and tundra near the arctic tree-line. They then winter in large numbers throughout the northern United States and south to northern Arizona and New Mexico.

So, it was a good morning, and the forecasted high winds never materialized. Yay!

Good birding!
