Parrot Conservation and Extinction Risk: Developing a Modelling Framework


Parrots are one of the most threatened group of species on the planet, due largely to habitat loss and poaching for the pet trade.  The yellow-shouldered amazon parrot in Bonaire, Netherland Antilles, is a threatened species, but on an island where past research, government support and local interest make research into the factors underpinning conservation strategies and extinction risk very possible.

Building on several years of data on reproductive performance, an extensive ringing programme and detailed habitat and food use data, I will focus on constructing several mathematical models of population growth and extinction risk. I will extend these baseline models to consider the effects of habitat loss, tourism development, and climate change on population growth and extinction risk. The models will be further expanded to integrate socio-economic data to develop cost-benefit scenarios for conservation intervention.

The project is supported by the World Parrot Trust (; CASE partner) and will involve collaboration with both the Trust and the ECHO foundation on Bonaire (
