Can You Overfeed Wild Birds?

As a general rule, wild birds eat only until their stomachs are full.


Wild birds rarely lose the ability to find their own food.
Most birds have what is known as a crop—a tube in the throat that allows only a certain amount of food to reach the stomach at any given time. .

When feeding birds, ensure that food is not stale or rotten, as this can be far more harmful to the birds than overeating. According to Colorado State University, the digestive enzymes produced by a bird's pancreas may not react well to rotted food.


It is generally difficult to gauge how fat a wild bird is by its appearance. Most wild birds are so heavily covered in feathers that it is impossible to determine the body weight with a visual inspection.
