The foraging behavior of two waterfowl species found in the marsh region of Lake Lagunita, the Mallard duck and the American coot, was observed for a total of four days. At each time interval of 6 am, 8 am, 10am, 12 pm, 2 pm, 4 pm, 6 pm and 8pm, the percentage of foraging birds within each species was recorded in order to determine at which time of day the American coot and the Mallard duck foraged most intensely. Although the results were not statistically significant, qualitatively the American coots were found to forage most intensely at noon and the Mallard ducks foraged most intensely at 6 am. By concentrating their intense foraging activity at different times of the day, I conclude that the Mallard duck and the American coot use different temporal foraging niches to avoid interspecies competition.
