On a beautiful, but windy, Sunday morning, we convened at Sandstone Ranch in Longmont. Sandstone Ranch is named for the sandstone cliffs in the area which formed when Colorado was part of an inland sea. The ranch itself was owned by the Coffin family back in the 1860’s. The original house, which still stands, is currently in use as the park’s visitor center.
Wind is some of the worst weather for birding because it tends to suppress the movement of smaller birds but, happily, around the windbreak of the cliffs we did see some White-crowned Sparrows, an American Goldfinch, and a Northern Flicker. A common misconception is that American Goldfinches migrate because in the winter they’re less visible, being more of a drab olive-brown color rather than yellow. However, they’re resident birds here along the Front Range. Listen for their squeaky little chirps or their “potato chip” flight calls.
We had several raptors on our walk, including three Red-tailed Hawks, a Northern Harrier, and a very obliging female American Kestrel. Kestrels, our smallest falcon, are one of the few raptors known to hover, meaning they will rapidly flap their wings to remain in place in the air. Hummingbirds also do this as will Belted Kingfishers. However, this particular kestrel wasn’t hovering, but kiting, which is using the wind to stay aloft rather than flapping.
Finally, we had some great waterfowl. While the majority of ducks we saw were Mallards, we did see both a pair of American Wigeon and Wood Ducks. We also had several thousand Cackling and Canada Geese, a couple of Ross’s Geese, and a good number of Snow Geese in the agricultural fields next to the Peschel Open Space, another natural area adjacent to Sandstone Ranch. Snow Geese are named for their, often, snowy-white plumage, but Snow Geese can also come in a “blue” color phase, where the majority of their feathers are a slatey-grey or “blue” color. Because of the warming of the arctic, Snow Geese are increasing in number rather than declining like many other bird species.
Because of the wind we only saw 18 species, but it was a beautiful day and great company. Hopefully you can join us next time!
