DENVER (CNN) – Something is terrorizing walkers and runners at Denver’s Sloan Lake, but it’s not probably what you think.
Hanging out in the bushes, swooping down and surprising unsuspecting joggers and pedestrians – is a blackbird.
The bird flaps its wings and makes a noise that some people find unnerving.
A bird expert from Denver’s Audubon Society says it’s a male red-winged blackbird.
And while he says this behavior isn’t common, he says it’s not uncommon either, if the bird is protecting a nest.
