The Brown Pelican is a large water bird famous for its distinct body shape and dramatic feeding habits. Known for their habit of diving headfirst into the water to catch fish, they are a staple along the coasts of the southern United States.

Appearance: Brown Pelicans are easily identifiable due to their long, curved necks, stout bodies, and large bills with a stretchy pouch. As their name suggests, they have brown and gray body feathers, with a paler head and neck that can become yellowish in breeding season.

Found on every continent except Antarctica, the Osprey is a cosmopolitan species favoring habitats near water bodies such as lakes, rivers, and coastal areas, reflecting its piscivorous diet. This bird has a diet almost exclusively of fish, making it a unique member of the raptor family and often referred to as the sea hawk or fish hawk. They locate their prey from the air, often hovering before plunging feet-first to capture a fish. When it comes to breeding, Ospreys are monogamous, often mating for life.

They construct large, bulky nests made of sticks, lined with softer materials, and prefer elevated or isolated areas such as treetops or artificial structures like utility poles. Both parents share the responsibility of incubating the eggs and rearing the chicks.
