Turkey Week Birding

We spent most of this week at our aunt's house in Aurora, and since our cousin Victor is also now birding, we were out birding most of the time. We met them for lunch in Boulder on Monday (the 24th), and since the Long-tailed Duck at Baseline Reservoir was still being reported, we tried again. There were Buffleheads, Common Goldeneyes, Red-breasted Mergansers, and Ring-billed Gulls, but again we missed seeing the Long-tailed Duck and the Surf Scoters. We didn't bird there for very long, as the traffic was very loud and distracting. Heading for a quieter place, we stopped by Walden Ponds, which was much more active. We saw 23 species.

On Tuesday, the 25th, we birded some new territory, Arapahoe County. We got out to South Platte Park near Littleton a little before noon. Joel and I were surprised by the number of ducks in the South Platte River. It took us about an hour to even get to the first lake! One of our most surprising finds was a male Mallard x Northern Pintail hybrid that was hanging out with some Mallards in the river. The camera I use for digiscoping was not working properly, so we relied on Aunt Diane's camera to get photos.

Another unexpected sighting was a late Blue-gray Gnatcatcher, spotted by Victor, that was by the bird viewing blind. There were lots of waterfowl on the lakes, even more than on the river. But perhaps the highest quantity of birds were the ones passing overhead, a couple hundred Canadian Geese and several Common Mergansers. There were also signs of the bird life that had been here during breeding season, signs in the form of old bird nests. It seemed to us that there was a nest in every tree, some of which were just two feet off of the trail!  We also saw two large wasp nests.

On the way home we stopped at two city parks, Utah and Expo. Utah Park hosted hundreds of Canadian Geese and some Cackling Geese, as well as the normal group of tame Mallards waiting for a hand-out. Among the Mallards we also found a pair of American Wigeons, which were just as tame as the Mallards. Expo Park had less individuals, but more species. We saw Canadian Geese, American Wigeons, Mallards, Northern Shovelers, Ring-necked Ducks, Common Goldeneyes, Buffleheads, and American Coots.

On Wednesday, the 26th, we birded Cherry Creek State Park. It wasn't quite as active as South Platte Park, but it was still a lot of fun. We got out earlier today, around 8 o'clock in the morning. There had been a lot of cool and rare things reported here lately, but we didn't see any of them. One of the highlights from this trip was a couple of Bonaparte's Gulls in a flock of Ring-billed Gulls on the south side of the reservoir.

Before heading back home for lunch, we stopped at one of Victor's favorite birding spots, Bluff Lake. The lake was low, but there was still a lot of waterfowl. There was also a large thicket of Giant Reed Grass, which is an exotic and invasive species.

You might have the impression that this was a boys only birding week, but without Aunt Diane as our driver and birding companion, we wouldn't have gotten very far!  Thanks Aunt Diane!
