An evening set aside for ringing juveniles of the year with ERB. The Barn Owls in their specially build shed have three young in the box, between 4 and 5 weeks old. Two adults emerged as we entered the shed and although these evaded the hand net at the access hole of their box the nestlings were quickly ringed. Barn Owl hatching is asynchronous so ages of owlets can differ by up to three weeks. Incubation starts with the first egg with additional eggs laid over the next 8 to 21 days.
The third and oldest owlet had primary feathers emerging
So apart from the Barn Owls we were unsuccessful but we had an unexpected bonus, successfully observing the female Beaver feeding on the opposite bank of the ditch. In a year of monitoring the birds in the beaver enclosure, this is our first clear sighting of beaver.
