Hudson Gardens Bird Walk, January 27th, with David Chernack and Jennifer O’Keefe

Beautiful blue skies made for excellent birding this past Saturday morning along the South Platte River at Hudson Gardens. A wide range of birds were seen, from a tiny Ruby-crowned Kinglet to an enormous juvenile Bald Eagle and everything in between!

Our walk largely consisted of hugging the South Platte, keenly eyeing the only non-frozen water in the vicinity for large numbers of waterbirds. Present in huge numbers were Cackling geese, which actually vastly outnumbered their more well-known relatives, the Canada geese. Amongst the large number of Cackling and Canada geese was one “gray goose” from the genus Anser, which includes the Ross’s geese and Snow geese. Those species are uncommon but regular winter visitors to the greater Denver area, and associate with Cackling and Canada geese while here; in their breeding grounds, they also hybridize with them, creating a broad and confusing spectrum of hybrids which can be difficult to identify. Our mystery goose gave our group the impression of a Canada X Ross’s goose hybrid, but it flew off with several Cackling geese before we could make the final call. Shame!

Also present along the river were Denver’s usual cast of winter characters, including Ring-necked Ducks, Mallards, Green-winged Teals, Gadwalls, and Hooded Mergansers. Not seen on our previous excursion to Hudson Gardens, two female Common Mergansers were present along our route, with one individual which was preening gave us excellent scope views. A mated pair of Common Goldeneyes were also found amongst the other ducks, and showed off their bright breeding plumage. A handful of Buffleheads energetically foraged as we advanced along the river, diving below the surface and quickly resurfacing.

Our group found a surprising diversity of landbirds along our route as well. A unique surprise was seeing a Ruby-crowned Kinglet, a tiny bird filled with energy. Interestingly, the bird was foraging alongside some sparrows and Brown Creepers. A distinctly not tiny bird which we spotted perched atop a telephone pole was an impressive immature Bald Eagle; the bird was just beginning to show off its distinctive white head plumage. Also seen were two cantankerous Belted Kingfishers, a pair of Northern Flickers, and a single Red-breasted Nuthatch.

  1. Very much enjoyed both David and Jennifer, both patient, supportive of those of us who know nothing, and much fun! Loved that when I told David I couldn’t fit into birding groups because I get too excited about seeing an adorable duck, he said he was the same way and he was! Jennifer was great at finding things in her book to share, and patient, too. Truly a lovely way to spend a morning and I love learning about the birds, especially the ducks who don’t flit off so fast! Will take a long time, though, to learn names and remember, so hope to come more often and practice! Thanks for giving us the lists afterwards to help us remember and please thank David and Jennifer for such a lovely bird/duck experience along my dear Platte River!

    1. Thanks so much for going on a bird walk at Hudson Gardens with David and Jennifer. We also do free bird walks the first Saturday of every month at the Front Range Birding Company. I hope you can make one of them! David and Jennifer are great birders and trip leaders. We also have Chuck Aid and Chip Clouse as leaders. Check out our events at or just call us at 303-979-2473 to sign up.
