No other common Gull possesses a red bill – making it easy to identify Heermann’s Gull. They are also the darkest of the common gulls. Heermann’s Gulls kleptoparasitize Brown Pelicans by snatching fish from their pouches. Brown Pelicans are so successful at catching fish, Heermann’s Gulls are thus more likely to attack them. Such is the life a bird!
