American Flamingo
Where and when to see the American Flamingo
DraftMostly in Yucatán state
It lives in shallow, salty coastal lagoons, feeding with its head upside down to filter the mud. From Cancún the nearest are around Holbox; the big flocks are at Ría Lagartos and Celestún.

Filters small crustaceans and algae from shallow salty lagoons with its head upside down. The peninsula's flocks breed at Ría Lagartos and spread along the north coast, including the lagoon behind Holbox.
- Identification
- A very tall, slim wader that is bright pink all over, with a long neck, long pink legs and a pink bill with a black tip. In flight it shows black flight feathers. Immatures are paler and greyer.
- Voice
- Goose-like honking and cackling, which carries a long way from a large flock.
What the photo doesn’t show
DraftRed milk for the chicks
Both parents feed their chick crop milk, a fatty secretion from the upper gut, for up to six months. In the first weeks it is bright red. That colour comes from a carotenoid pigment called canthaxanthin, not from blood. 1
Nesting east, wintering west
The Yucatán flock nests at Ría Lagartos and spends the winter mostly at Celestún, about 280 km west. Chicks banded in the colony turn up at Isla Pájaros, Celestún once the winter northerlies (nortes) arrive. 2,3
Mexico’s first Ramsar site
The flamingo colony near El Cuyo is why Ría Lagartos was first protected, in 1979. When Mexico joined the Ramsar wetlands convention on 4 July 1986, Ría Lagartos was the only site it designated. 4,5
Best seen from a distance
The Ramsar sheet for Ría Lagartos names tourists getting too close for photos as the main impact on the flamingos. Flamingos spend about 48% of their time feeding, and boats that flush them cut that time down. 4
