Classic low-frequency haunting trilling calls from mother Screech Owl Live From the Nest Box - March 24th. Her whole body will shake as she make this rhythmic call about every 45 to 60 seconds. Sitting on three eggs all day - Mother owl will be ready to leave the nest box briefly around dusk and meet the male who will be waiting for her with food. Before she leaves you will hear them call each other and make contact. She will go back and forth to the nest a few time during the evening and the male will likely bring her food several times. Some nights they can be a bit chatty, but mostly for now her focus is on incubating the egss. Hatching of the three eggs is expected to begin around March 29th.
