Hudson Gardens, February 24, with Chuck Aid and David Chernack

The Snowman Stampede is a 5K, 10K, and half marathon race held every February in Littleton, and this year it was held on the day of our bird walk at Hudson Gardens. Fortunately, we were mostly able to do the necessary dodging when required, and were not significantly impacted by the hundreds of runners.

Our Mountain Bluebird was a big surprise for our group; they are very irregularly seen in suburban habitat so early in the year. (c) David Chernack

Here at the end of February we are on the cusp of so many interesting bird activities. First, and foremost it appears that the same pair of Red-tailed Hawks that were around last breeding season have returned to the area. These guys tend to hang out just across the river from Hudson Gardens, and are remarkable because while one is our standard light-morph western Red-tail, the other is an intermediate, or rufous-morph, western Red-tail. The variety of plumages that Red-tailed Hawks exhibit is truly incredible. Without going into too much detail, just know that there are 12 sub-species of Red-tails each tending to have either a dark or light morph, with some intermediate colored birds, and then you have the different plumages exhibited by juveniles versus adults. It can be quite the smorgasbord for us birders, as well as quite confusing!

Hooded Mergansers are a uniquely beautiful diving duck. The males we observed (like this individual) were a treat. (c) David Chernack

We are also commencing waterfowl spring migration which peaks towards the end of March (to be followed shortly thereafter in mid-April by the peak of shorebird migration). This is all by way of saying that we saw a good variety of geese and ducks (13 species). These guys are all in wonderful breeding plumage right now, and it’s a great show!

Bushtits are tiny cousins of chickadees that are constantly in motion, making them a challenge to photograph. (c) David Chernack

Other highlights included a few species that tend to be around throughout the winter, but one can never be guaranteed of seeing them: Killdeer, Bushtit, Brown Creeper, and Ruby-crowned Kinglet. This last is one of North America’s smallest songbirds wintering in a variety of habitats, and then here in Colorado breeding up in the Spruce-Fir Forest.

The aptly named Common Goldeneye is quite a looker with its bright white sides, dapper face coloration, and of course, its golden eye. (c) David Chernack

Finally, one other bird that can be here illusively in the winter is the Mountain Bluebird. We were fortunate to get several good looks at this outstanding fellow.

Thanks to those of you who braved the Snowman Stampede and the chilling winds that were with us almost all morning. And thanks to David Chernack for his excellent photos!

Good Birding!
