Red deer
The native Irish red deer in Donegal went extinct around 1860 and were re-introduced in the 1890s. Due to interbreeding, most deer in the county are now a Sika-Red deer hybrid. The Wild Ireland wildlife park near Burnfoot showcases some of Donegal's historic animal species that were hunted to extinction, including brown bears, lynxes and gray wolves. In 2001, the golden eagle was re-introduced into Glenveagh National Park and is currently Ireland's only breeding population.
