Birding the DIA Raptor Alley (Co-sponsored trip with DFO)

If you had attended a similarly named trip in November, December 2025; January or February 2026 , please do not sign up for this trip as well, in order to allow others to experience what you had . This is an exploration of Denver’s eastern prairie for raptors. This trip will focus on raptor ID and it will be a good opportunity for those who want to go to the next level of identifying the species in greater detail, such as aging individuals, determining sex, and identifying individuals to subspecies. For example, determining adults versus juveniles when they are distinctive (e.g., accipiters, Golden Eagle, Ferruginous Hawk, falcons); males versus females versus juveniles (e.g., Northern Harrier); identifying the Eastern borealis versus Western calurus and Harlan’s harlani subspecies of Red-tailed Hawk; identifying Bald Eagle to a specific age from juvenile to fifth-year; identifying dark morph raptors if we are fortunate enough to see them. Of course, this trip will cater to beginners as well. We can talk at different levels to different levels of birding. We will be stopping at Barr Lake later so if you have a State Parks pass, that would be helpful. Bring binoculars, scopes and cameras (if you have them), snacks, water.

This trip is led by Ajit Antony and Liza Antony.
