This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
|Range Description:||This species is found in the Americas, breeding along the Pacific coast from California (USA) to Chile and along the Atlantic coast from South Carolina (USA) through the West Indies to Venezuela, ranging as far as Canada and Tierra del Fuego (Chile) in the non-breeding season (del Hoyo et al. 1992).|

|Population:||(Wetlands International 2006)|
|Habitat and Ecology:||This species inhabits shallow inshore waters, estuaries and bays, avoiding the open sea. Its diet is comprised mostly of fish, causing great congregations in areas with abundant prey. Prey species include sardines and anchovies, but has been seem to take shrimps and carrion, and even nestling egrets. It regularly feeds by plunge-diving and is often the victim of kleptoparasites. The timing of breeding varies depending on latitude, breeding in spring in the extreme north of its range compared to all year round in the tropics. Brown Pelicans are colonial, with some colonies being maintained over several years. It mostly nests on the ground, sometimes on cliffs and less often in small trees or bushes. Movements and migrations depend on local conditions (e.g. northern populations migrate south) (del Hoyo et al. 1992).|
