A bird of the Yucatán coast
The flamingo you'll see in Yucatán is the Caribbean flamingo, also called the American flamingo, Phoenicopterus ruber. According to Mexico's National Commission of Natural Protected Areas (CONANP), it ranges along the entire peninsula coast, but its key sites are two biosphere reserves: Ría Celestún in the west and Ría Lagartos in the east. Both offer shallow, brackish water for feeding and resting.
Why flamingos are pink
Flamingos aren't born pink; chicks are grayish. The color comes from their diet. CONANP explains that the pink plumage is linked to what they eat: small organisms in brackish water loaded with pigments that build up in the birds' feathers.
That's why the shade can vary from bird to bird. The wingtips are black, which you only really notice when a flamingo takes off.
Size and appearance
CONANP puts an adult flamingo at roughly 0.8 to 1.5 meters (about 2.6 to 5 feet) tall, with males usually larger than females. Long legs let it wade through shallow water, and its bent bill works like a strainer: it dips its head upside down to filter food from the water.
Where it nests and how far it travels
The Caribbean flamingo nests on the peninsula, but the exact spot shifts with weather conditions. CONANP names Ría Lagartos, Ría Celestún and San Crisanto as nesting sites.
It also moves with the seasons. In winter, the biggest regional concentration is between Ría Celestún and Los Petenes in Campeche; toward summer, many move to Ría Lagartos and Yum Balam in Quintana Roo.
Thanks to banding programs, CONANP has recorded Yucatán-banded flamingos turning up in the United States, Cuba, the Bahamas and the Cayman Islands.
A 25-year conservation program
Since 1999, CONANP has coordinated a regional monitoring program. Between 1999 and 2024 it recorded 154,446 chicks hatched and banded 7,142 birds. Counts vary from year to year; they describe specific periods, not a fixed population.
That variation is exactly why no tour can promise flamingos: they depend on each season's water, food and weather.
Seeing flamingos from Mérida
Mary Tours offers three ways to look for flamingos in their habitat: the Celestún boat tour through the estuary, the Las Coloradas and Río Lagartos trip with a ride through the mangrove channels, and the Sisal kayak trip through the coastal wetland. On all of them, sightings depend on the season and happen at the distance the reserves require.
The office is on Calle 61 in Mérida's historic center; schedules and prices are in the booking section.
