Owl Calls

Owl expert Chris Sperring uses his own methods to hear different owl calls.

Chris visits an area of woodland to look for tawny owls and discusses learning to make their call. He also explains the problems of over-using calls when looking for owls.

Chris delves into the role of calls when young owls look for new territory, and how it functions in nesting and territorial behaviour.

Plus, the difference between male and female calls.
