Domestic and Feral Dogs Threaten Flamingo Populations on Holbox Island

Holbox Island, Quintana Roo — Residents of Holbox Island have reported that domestic and feral dogs are harassing and dispersing colonies of flamingos in critical resting and nesting areas, threatening the birds as they begin their annual arrival to the island.

The situation, attributed to irresponsible pet ownership and the absence of local regulations for responsible pet guardianship, leaves authorities without legal tools to sanction such behavior within the island’s Protected Natural Area.

The arrival of Caribbean flamingos is not only a visual attraction for visitors but also a key component of the local ecosystem and a primary economic activity linked to tourism on the island.

Witnesses documented two dogs with owners chasing and frightening the birds in critical feeding and resting sectors. While owners argue their pets are trained, ecology experts warn that the mere presence of dogs or cats—considered invasive species in protected natural areas—causes indirect disturbances to wildlife.

According to personnel from the National Commission of Natural Protected Areas (Conanp), the scent trail and proximity of these animals generate high stress levels in the flamingos, forcing them to abandon areas used for feeding.

“Ninety percent of reports of attacks or disturbances to wildlife on the island come from dogs with owners, not from stray animals,” sources from the commission said.

The situation highlights a structural contradiction: while the tourism sector promotes flamingo watching as a main attraction, part of the population and some businesses allow pets in restricted spaces.

The problem also has an administrative origin. During the previous municipal administration, an animal census began in coordination between Conanp and the Ecology Directorate with the goal of drafting responsible pet ownership regulations; however, the project did not advance and, following the change in administration, follow-up was suspended.

Island residents lamented that biodiversity protection depends solely on the will of pet owners due to the lack of coercive sanctions. They also noted that a lack of coordination between municipal authorities, tourism businesses, and civil society leaves park rangers in a vulnerable position, as their work is limited to issuing verbal exhortations that are frequently ignored.
