Adorable New Arrivals: Flamingo Chicks Hatch in Mérida Zoo
The Bicentenario Zoo Animaya in Mérida has announced the birth of six flamingo chicks, a significant achievement for the facility in its role as a Wildlife Conservation Center.
The fledglings are in good health and are quickly being integrated into the rest of the colony, marking a new chapter in the zoo’s ongoing efforts to protect this iconic species of the Yucatán Peninsula.
A Dedicated Flamingo Breeding Program
Since 2016, Animaya has operated a formal reproduction program for the American flamingo (Phoenicopterus ruber). This species is not only emblematic of the region but is also classified as threatened under Mexican official norms. The successful hatching of these six chicks underscores the importance of such conservation initiatives in safeguarding the species’ future.
The breeding season for flamingos occurs during the spring. Each pair lays a single egg, and the zoo’s staff plays a proactive role in preparing for this event. Early in the year, zookeepers construct mud nests, which dry before being placed in the nesting area.
The breeding pairs then select a nest and construct it themselves, a process that mirrors their natural behavior.
Nesting and Early Life
Flamingo nests are distinctive pillar-shaped mounds built from mud, stones, grass, and feathers. Both parents collaborate in building the nest and share incubation duties. The chicks are precocial, meaning they are relatively mature and mobile from the moment they hatch. They abandon the nest within a few days of birth.
Despite their early independence, the young flamingos are entirely dependent on their parents for food. They are born with straight bills that are not yet functional for filtering food from the water.
To nourish them, the parents produce a nutrient-rich substance known as crop milk or “líquido ingluvial,” which they feed to the chicks beak-to-beak. This intensive care comes at a cost: during the rearing period, the parents lose their characteristic bright pink coloration.
The vibrant pink hue of adult flamingos is not present at birth. The chicks hatch with soft white down, which they later molt into grey plumage. They acquire their famous pink color over time from the algae and crustaceans that make up their diet.

The Challenges of Captive Breeding
Breeding flamingos in captivity presents unique challenges. One of the primary difficulties is the size of the flock. In the wild, flamingos are highly social birds that live and breed in massive colonies, sometimes numbering tens of thousands. This communal living and synchronized breeding behavior are difficult to replicate in a zoo setting.
Furthermore, flamingos are exceptionally sensitive to environmental changes. In their natural wetland habitats, excessive rainfall can alter salinity levels, flood nests, drown eggs, and dilute or disperse their food sources.
Conversely, reduced rainfall increases salinity, decreasing food availability and limiting the mud needed for nest construction. These same environmental sensitivities mean that zoos must meticulously manage habitat conditions to encourage breeding.
Engineers of the Ecosystem
Beyond their aesthetic appeal, flamingos play a crucial ecological role. They are considered the engineers of coastal wetlands and mangroves. As they filter water and mud with their specialized bills, they oxygenate the soil and regulate populations of microorganisms and small crustaceans. This activity helps keep the water clean and suitable for other species, highlighting their importance to the overall health of their ecosystem.
Visiting the New Arrivals
The new residents of Animaya can be visited from Tuesday to Sunday, between 8 a.m. and 5 p.m. In addition to the flamingos, the park offers other attractions such as the Felinario, the Estela, and the Botanical Garden. The arrival of these six chicks is a testament to Animaya’s commitment to wildlife conservation. It offers visitors a unique opportunity to witness the early stages of life of one of Mexico’s most treasured bird species.
Seeing Flamingos in the Wild
For those wishing to observe flamingos in their natural habitat, the Yucatán coast offers several remarkable sites. The two most prominent are the Biosphere Reserves of Celestún and Ría Lagartos, both of which are vital sanctuaries for the American flamingo.
Celestún, located roughly 90 kilometers (56 miles) west of Mérida, is considered the region’s most important sanctuary, with large concentrations of birds typically seen there between November and March.
As the seasons change, the flamingos migrate eastward towards the Ría Lagartos area and the nearby pink lakes of Las Coloradas, where the breeding and nesting season generally takes place from March to September.
Beyond these two main hubs, flamingo colonies can also be spotted in other coastal ports and estuaries, including Sisal, Chuburná, Telchac Puerto, Xcambó, and El Cuyo, making the entire Yucatán shoreline a potential haven for these iconic pink birds.
