Some audio, taken two days ago, of two well-grown Long-eared Owl chicks calling from a wooded area near Newmarket. These are the chicks recorded in an earlier post HERE. Compare how much stronger their voices are after 18 days. The two are calling alternately from perches high in trees about 30 metres apart and the sound was carrying for almost 700 metres on this calm, still night.

The young owls are flying competently at this stage, and were well away from their nest.
