In 2011, Ecostudies Institute, in partnership with the Florida Fish and Wildlife Conservation Commission, U.S. Fish and Wildlife Service, and the National Park Service, completed a 4-year study of the birds that breed in Florida’s mangrove forests. We estimated the abundance and mapped the distribution of mangrove landbirds, quantified habitat associations, and produced a series of recommendations for implementing a long-term monitoring protocol for mangrove landbirds.

Florida’s mangrove forests are home to several bird species – including Mangrove Cuckoo, Florida Prairie Warbler, Cuban Yellow Warbler, Black-whiskered Vireo, and White-crowned Pigeon – that do not occur anywhere else in North America. Prior to our research, very little was known about any of these species. The work we have done on this project is important because it provides information that is needed if we are to conserve populations of mangrove landbirds.

 

Key Findings

  • Red-bellied Woodpecker, Northern Cardinal, Florida Prairie Warbler, and White-eyed Vireo are the most common species. Of this group, only Florida Prairie Warbler is restricted to mangroves.
  • Black-whiskered Vireo was widespread but less abundant than Florida Prairie Warbler.
  • White-crowned Pigeon, Gray Kingbird, and Cuban Yellow Warbler were detected only in the Florida Keys and on the islands of Florida Bay, but were found in high densities where present.
  • Mangrove Cuckoo was found throughout the mangroves but occurred at very low density and at only a small percentage of survey points.
  • In the 10,000 Islands region, populations of Mangrove Cuckoos and Black-whiskered Vireos have declined by 87% and 64%, respectively, between 2000 and 2008. This work was published in the Journal of Field Ornithology.
  • Populations of all mangrove landbirds could be monitored by repeating these surveys every 3 years.
