Arctic Terns over Darley Dale

In the early hours of Sunday morning Simon recorded Arctic Terns calling as they flew over Darley Dale using his nocturnal audio recording set-up.

Although Arctic Terns are recorded regularly on spring passage at both Carsington and Ogston reservoirs they are rarely recorded away from these water bodies, although they must clearly pass over inland areas as they travel to and from the coast.

This is another example of continuous audio recording giving an insight in to nocturnal movements of birds which we would otherwise be unaware, like that of migrating common Scoter which has been noted previously.

You may need to turn your speaker up to hear what is clearly more than one individual calling (© Simon Roddis)
