Brown Pelican (Pelecanus occidentalis) are dark and bulky. The sexes are similar in plumage and both are 4-4.5ft long. The huge naked skin pouch suspended from the lower half of the hooked bill holds 2 or 3 times more than the birds stomach. The pouch also pulsates in extreme heat to allow cooling,Pelicaniformes are the only birds that share in common a totipalmate foot,that is,one in which all 4 toes,including the hind one,are united by a web of skin.
