White-faced Ibis range map credit https://www.allaboutbirds.org/

Scientific Name: Phoenicopterus roseus

Average Length: 110 - 150 cm (43 - 59 in)

Average Wingspan: 140 - 165 cm (55 - 65 in)

Average Weight: 2 - 4 kg (4.4 - 8.8 lbs)

The Greater Flamingo is the largest and most widespread species of the flamingo family, instantly recognizable by its long, thin neck and legs, and its vibrant pink feathers.

Appearance: Greater Flamingos have a distinct appearance, characterized by their long, curved neck, sticklike legs, and pinkish-white feathers. Their bill is pink with a distinctive black tip. The legs are also pink, adding to their flamboyant look. They are the largest flamingo species, standing about 3.9 to 4.7 feet tall.

Diet: Greater Flamingos primarily feed on small organisms like crustaceans, mollusks, and microscopic algae. They use their unique, specially adapted beak to filter these tiny creatures from the water. The pink coloration of their feathers comes from pigments in the crustaceans and algae they eat.

Reproduction: Greater Flamingos are monogamous birds that breed in large colonies, sometimes numbering thousands of pairs. They build mounded nests from mud where the female lays a single egg. Both parents share the responsibility of incubation, which lasts around 30 days. The young flamingo is fed a nutritious milk-like substance produced by both parents.

Its large surface area and ecological richness make it an ideal stopover for migratory birds.

  2. San Francisco Bay: Known for its rich estuaries, it’s a prime location to spot Double-Crested Cormorants, American Avocets, and other waterfowl. The Don Edwards San Francisco Bay National Wildlife Refuge is a particular hotspot, where you can find diverse bird species year-round.

  3. Mono Lake: This ancient saline lake located in Mono County is famous for its tufa towers. The lake is a crucial nesting habitat for California Gulls and is also known for its population of phalaropes and grebes. Its unique ecological features provide a haven for various bird species.

  4. Sacramento National Wildlife Refuge: The refuge offers a great diversity of bird species, especially during winter. Northern Pintails, Greater Scaups, and White-Faced Ibises are among the species seen here. The refuge’s wetlands, grasslands, and riparian habitats support a myriad of water birds.
