Found the cause of tweeting in the shed.
Five hungry little robins.
Update 15 May. Success as all five fledge and leave the nest.
The female’s sitting down a lot.
Tada! This is why.
Over the next few days more appear.
That should be all. It’s more than we normally have and they probably won’t all hatch, and the ones that do certainly won’t all survive.

Spring is late, the pond is still full and not much is growing yet.
Last month a lone female took a liking to the new owl box and quickly settled in. Not long after, she started bringing a fella back and they are now officially a couple. No signs of eggs yet but it shouldn’t be long.
19 March 2023. Having set up a third camera on the ledge we’ve managed to work out the leg ring numbers on each owl. The male is a young barn owl, hatched last year at a site five miles from here, and the female much older, almost five years old and has come from a site about nine miles away.
A tawny owl takes an interest in the nest box but realises it’s already occupied.
And the frogs and toads are gathering. The toads have appeared first, in great numbers, as they head towards the pond. Some can’t wait until they get there.
A gang of male common frogs writhing around a lone female (somewhere in the middle).
We’ve taken advantage of the nest box being empty over the winter to replace it with a new one, and have updated the cameras too. Now we wait…
We didn’t have to wait long, two owl pellets appeared overnight: proof of an owl visiting to check out the new accommodation, which must smell strange to them as it’s so new.
The visiting heron took advantage of us being away for a few days. A beautiful sight but oh, the poor fish!
The older owlet has already dispersed and the younger one comes back occasionally to the nest box, but doesn’t stay. The end to a difficult but successful breeding season.
This evening the younger owlet found enough courage to leap off the nest box ledge for the first time, though rather inelegantly flew straight into a bush. She made a good recovery though and has now flown off to shelter from the rain in a nearby oak tree.

The older owlet has already learnt to fly and last night spent most of her time away from the nest box, leaving her younger sister alone to sit on the ledge in the early morning light, before going for a solitary daytime sleep.
