Red-Winged Blackbirds are very common in Colorado. They are permanent residents in most local parks, including Cherry Creek State Park, where I captured one of them while it was singing to attract a female. Spring is a great time for birds in Colorado, except when it gets very cold. It snowed today in Denver and the temperatures dropped below 40F, which is not abnormal for Colorado in April :)
Hoping for a sunny day next week, so that I can get out and do some spring birding!
Captured with Nikon D3s and Nikon 300mm f/4.0 AF-S + 1.4x TC.
