Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Pelecaniformes, Family: Pelecanidae, Genus: Pelecanus, Species: occidentalis
Family: Pelecanidae (Pelicans)
- Shape
- Asymmetrical vane with a narrower leading edge and a broader trailing edge; slightly curved with a rounded-to-blunt tip; lacks prominent emargination seen in higher primaries.
- Size
- Estimated 25-30 cm (10-12 inches) in length; consistent with an adult Brown Pelican primary which typically ranges from 20 to 35 cm depending on the specific position.
- Rarity
- Common; frequently encountered along the coastlines of North and South America.

Description
Large, iconic coastal bird with a long bill and expandable throat pouch. This feather is a deep, earthy brown, matching the primary plumage of an adult. Brown Pelicans are famous for their dramatic plunge-dives from heights of up to 60 feet to catch fish. They have a massive wingspan (6-7 feet) and a heavy body, requiring these strong, broad feathers for lift.
Colour & Pattern
Uniformly dark chocolate brown to silvery-grayish brown on the dorsal surface; the rachis is notably pale/creamy white near the base, darkening toward the tip; ventral surface is a more matte silvery-brown.
Barb Structure
Densely interlocked pennaceous barbs providing a rigid, wind-resistant surface for flight; minor plumulaceous barbs at the very base (calamus); barbs appear relatively intact though slightly worn at the distal tip.
Texture & Surface
Stiff and somewhat coarse; the surface has a matte to low-gloss finish; the vane is quite rigid to withstand the force of plunge-diving and heavy flapping flight.
Key Features
Large size, dark brown coloration, very thick and pale rachis at the base, and notable vane asymmetry characteristic of a primary flight feather.
Habitat
Coastal marine environments, including estuaries, bays, and beaches; rarely found far inland except during extreme weather events; nests in colonies on islands or in mangroves.
Geographic Range
Year-round resident along the Pacific and Atlantic coasts of the Americas, from Washington and Virginia south to northern Peru and Brazil; non-breeding birds may wander further north.
Ecological Role
Top-tier coastal predator acting as an indicator species for marine health and fish stocks; their nesting colonies provide nutrients to coastal island ecosystems.
Similar Species
Double-crested Cormorant (smaller, darker/blacker rachis), immature Bald Eagle (usually broader with different mottling), or various Gulls (usually smaller with more distinct white/gray patterns).
Interesting Facts
Brown Pelicans are one of only two pelican species that catch food by diving into the water from the air. Their populations plummeted in the mid-20th century due to DDT poisoning but have since made a remarkable recovery.
Condition Notes
Fair to Good; shows signs of natural wear (abrasion) at the tip and edges, likely from sand or salt spray. The calamus is clean, suggesting a natural molt rather than a forced removal.
