Female kestrel

I have covered eagles, hawks, and  falcons in past Bird Sighting columns dating back to 2021. The most common eagle in Denver is the bald eagle, the most common hawk is the red-tailed hawk, and the most common falcon is the American kestrel. The  kestrel is the smallest among these raptors, about the size of a starling or a robin. I can’t believe I have not shared this ubiquitous bird of prey with you yet.

Male kestrel

Despite its small size, the kestrel is a fierce predator. It perches on wires or poles to hunt for insects and small rodents in open territory. You may  see it hovering during hunts by flapping its wings and adjusting its tail to stay in place. Recent population declines of this year-round resident of Denver have been noted, though nest boxes may reverse this trend.
