Some wildlife experts say they're noticing an increase in feisty fowl across parts of Illinois, thanks to a delayed nesting season.
Authorities say the long winter and spring floods washed out some nests, which means geese and other birds are getting a later-than-usual start laying eggs.
The (DeKalb) Daily Chronicle says that means the animals are becoming increasingly protective of their territory -- and their young offspring.
At the Oaken Acres Wildlife Center in Sycamore, one long-time volunteer was attacked by an angry goose last week when he walked by an area where the bird was nesting.
That man, David Bythewood, says people should maintain eye contact with an angry goose and raise their arms to protect themselves.
