Abstract
Monitoring the reproductive productivity of urban colonies of wild birds is paramount to understand their adaptation to anthropogenic environments. The White Ibis (Eudocimus albus) is a wading bird iconic to the Everglades ecosystem that has become ubiquitous to the urban landscape in south Florida. Despite having specific breeding requirements, the ibis has already established a few urban colonies. This study aimed at comparing the productivity of an urban colony of ibises to those in the Everglades. Nestling mortalities were also investigated and revealed three ibis with West Nile virus disease in 2020. The urban colony showed high Mayfield nest success rates in 2020 (70.8%) and 2021 (76.4%). The results presented herein suggest that urban colonies are potentially suitable for ibis breeding however, continued studies on additional urban rookeries are needed.
