Brown Pelican - a group of pelicans has many collective nouns, including a brief, pod, pouch, scoop and squadron. They can hold about three gallons of water (and fish) in its pouch. The Brown Pelican incubates its eggs in an unusual manner, it covers them with its webbed feet. This practice was detrimental to the species when the pesticide DDT was in common use. This pesticide caused thinning of the eggshells resulting in so many broken eggs that the species became endangered.
