Its real life angry birds in Denver Colorado this nesting season.

Residents near Sloan Lake have been attacked lately by nesting birds in the area.

Red-winged blackbird have been ambushing joggers and walkers alike as pedestrians have passed underneath nests.

No one has reported any serious injuries, encounters with these feisty feathered foes have startled many people in passing.

These attacks aren't malicious in intention though, but rather just a mother trying to protect her young.

So, until nesting season is over, enjoy the feisty encounters.
