He gave it to Sydney, bonded. then left 8:18. She ate it forthwith.
He returned 8:53 with 2nd treat – rabbit. She placed it in the pantry straightway. She stepped out for her FFN 9:28-9:32.
Syd consumed the rabbit 2:44. Mel landed on the roof 3:00 deeting. Henry flew by 3:01. Mel promptly gave chase.
How many of us spent the day looking at Syd's tail feathers waiting for a fifth impending egg? (Guilty)
We are all hoping that four eggs is the completed clutch for Mel and Syd, a much smaller clutch and less "asynchronous" hatching dates (ages) between them will help insure that they all will make it to fledge without the fierce competition for food between them.
Barn Owl Trust - Clutch size and brood size are directly related to food supply - the more food the adults have the more young they produce. Food supply is affected by habitat quality, prey density, the weather and the experience and behavior of the individual adult owls.
