The Cozumel thrasher (Toxostoma guttatum) is a bird from the mockingbird family (Mimidae), which is endemic to the island of Cozumel off the Yucatán Peninsula, Mexico. It is believed to be the most critically endangered species of bird in Mexico – if it indeed still exists, which is probable but not certain.
This bird is closely related to the long-billed and brown thrashers. It has been generally described as shy, but there have been descriptions to the contrary. It was once abundant throughout Cozumel before two hurricanes greatly affected its numbers. Invasive species are also thought to have impacted the population of the thrasher.
