Peak District Retreat Blog: Wildlife and general news about the Retreat and its environment

This evening, for the first time, the fourth and youngest owlet, 54 days since hatching, has managed to fly up from the base of the nest box and gain purchase on the exit hole. Its first three siblings have been exiting the box for a few days now, particularly the first two, achieving this for the first time at 56 days, 56 days, and 55 days respectively.

The first two hatchings have quickly become confident flyers. The third-hatched, at the right of the group (with its first outing being only two days ago, and still quite downy on the abdomen) is less confident but is nevertheless flying around.

At 56 days since hatching, the first hatched owlet has managed to fly up the box exit for the first time. It didn't venture out on to the ledge - it just clung on to the exit and looked around.

The parent twice brought it prey and tried to feed it as it clung there, but both times the prey was dropped onto the ledge. Perhaps the owlet was too focussed on clinging to the exit to manage to coordinate a food pass!

Soon it will be venturing out onto the ledge, and starting to fly around. It will return to the box, because barn owl parents only feed those at the box, not any that have left and not returned (even if they are stuck on the floor and can't get back to the box).

Expect a second owlet to also achieve this same milestone in the next couple of days.

The barn owlets are developing well and the first fledging is expected in around ten days.

To exit the nest box they need to be able to fly up to the exit hole which is about 60cm above the floor of the box. The box depth is calculated so as to be difficult for them to exit before 56 days old. This is because if they leave the box too early, before they are good enough at flying to get back to the nest box, they will starve. Barn owl parents do not feed their young on the ground, they feed only those in or on the box. (This is different to tawny owls who find their young and feed them wherever they are).

The eldest owlet will be 56 days old just nine days from now. Expect to see a lot of wing exercising and attempted flying between now and then. Already I've seen the eldest one leave the bottom of the box briefly by flapping its wings.
