Invasive Animals

Common redpoll

Carduelis flammea

The common redpoll is a small brownish-grey finch with dark streaks and a bright red patch on its forehead.  It has a black bib and two pale stripes on the wings. They are primarily seed-eaters, and often feed acrobatically. 

Common snapping turtle

The common snapping turtle is a large freshwater turtle. Adult snapping turtles are large, 20-37cm in carapace length, and males are larger than females. They are omnivorous. In early spring, when limited aquatic vegetation exists in lakes and ponds, they may primarily eat animal matter, however, when aquatic vegetation becomes abundant, they become more herbivorous.

It favours urban gardens and parks as well as agricultural regions where they feed on a variety of insects, fruits and seeds. This starling is very distinctive as breeding adults have a white-flecked appearance with bright yellow bill and glossy purple plumage around the head and shoulders.
