Bitterns

American Bittern

There are two bittern species in the United States, the American Bittern and the smaller Least Bittern.  Both species are generally shy and spend most of their time in weeds and cattails in wetland areas.

While American Bitterns have a strong affinity for wetland areas they can show up in some strange locations during migration. They also have a very unusual call.

Why are they attracted to my adult chickens.

@Tracy- It's hard to say but as with most wild animals, bitterns and other birds are usually attracted to food, or, the possibility of food. They might find some bugs or other small animals near the chickens, or, might try and snatch a young chick (yikes!). Or, the heron might be attracted to the sound and movements of the chickens in general and associate that with the possibility of food.
