Rat Predation Is A Major Factor In The Decline Of The Oriole In Recent Years. Known To Attack And Kill Mountain Chicken (A Near Endemic Giant Frog) Though The Population Impact Is Not Known (Mendes, S. (Unknown). Compiled database on Montserrat invasive species. Dataset); Ongoing Rat Control (Of Both R. Rattus And R. Norvegicus) In An Experimental Area Has So Far Resulted In A Steady Increase In The Abundance Of Tree Frogs And Dwarf Geckos Since Rat Control Began In 2006, Though The Data Have Not Yet Been Formally Analysed (Mendes, S.

Likely To Be Significant Predators Of Other Birds And Herptiles (Some Endemic), And To Affect Forest Ecology Through Predation Of Seeds, Fruits, Flowers, Seedlings And Invertebrates. Rats Are Also Considered To Be Major Agricultural And Public Health Pests. (Mendes, S. (Unknown). Compiled database on Montserrat invasive species. Dataset); Invasive.
