Early in January I photographed an American Coot being chased by two Mallards for the food it carried in its bill. American Coots are both intraspecific and interspecific kleptoparasites meaning that they will steal food from their own species and other species, I see that kind of behavior from them often with their own kind, less often with other species. Some ducks are also intraspecific and interspecific kleptoparasites.
In this photo the coot knew it was being chased and was swimming to the shoreline with its bill filled with aquatic vegetation as fast as it could with the two mallards on its tail. As the coot moved through the water the mallards were snatching up bits of the vegetation with their bills that fell out of the clump back into the water.
The coot had done the work of bringing the food to the surface, the mallards gained food without much effort on their part. The coot didn’t look very happy that the mallards were chasing after it but to be fair coots kind of look grumpy most of the time.
Life is good.
