Our star species are some of the most interesting birds you may see on your visit to the reserve.
Look along the rocky stream for dippers' weird and wonderful behaviour. As their name suggests, they plunge underwater looking for insect food and fish fry before bobbing to the surface like a cork.
Hen harriers breed on the moorland here. You may see the ghostly grey males or rich brown females quartering the land in search of prey.
You can see ravens' plummeting display flights from late winter, through the spring and hear their gruff, ringing 'kronk' calls throughout the year here.
The red grouse here belong to the Irish 'hibernicus' race. Listen out for their sharp 'go back, go back' or watch them flying across the heather.
Skylarks nest on the moorland at Aghatirourke. Watch them displaying and singing overhead in spring.
