Available at: https://doi.org/10.15468/ex7uxv);. Uproot Patches Of Heliconia Caribbea Lants, The Main Nest For Montserrat Orioles Ad A Valuable Food Source For Nectarivorous Birds And Insects. Loss Of This Plant May Also Increase Soil Erosion And Flooding Downstream. Mendes, S. (Unknown). Compiled database on Montserrat invasive species. Dataset; Believed To Trample And Predate Turtle Nests. In Medium Term They Are Likely To Have A Very Major Impact On Forest Ecology, In Particular Through Arresting Tree Succession By Eating Seedlings. They Are Thought To Predate Slower Moving Herpetofauna Such As Mountain Chicken And Perhaps If They Enter Its Range The Endemic Montserrat Galliwasp Diploglossus Montserrat (A Lizard). Often Reported As Eating Large Numbers Of Arthropods (Though Population Impacts Are Under Recorded) And Likely To Directly Destroy Mountain Chicken Nests By Their Extensive Digging And Wallowing Along Watercourses. May Also Disperse Seeds Of Invasive Plants Such As Psidium Guajava And Transmit Wildlife Diseases. (Mendes, S. (Unknown). Compiled database on Montserrat invasive species. Dataset);. Invasive.

Feral population is established from farm stock, and there are still periodic releases/escapes from farms. Became feral in mid 90s during the collapse of agriculture following the volcanic eruption. (Mendes, S. (Unknown). Compiled database on Montserrat invasive species. Dataset);
