West Cornwall Buzzing Team: Barn Owl 2022 upgrade


It’s been an unusual summer season for great deals of our normal tasks, with fanatic climate, bird influenza and also residues of Covid still making life hard. Several of our birds have actually made out especially severely, with Kittiwake minimized to simply one effective sitre throughout Cornwall, a sobbing embarassment.

Our Barn Owl tracking proceeded basically untouched though and also in spite of the dry spell, birds in fact appeared to do OK. The job remained to expand and also we directly went to over 100 boxes for the very first time, which is no mean task. Regardless of clutch dimensions being second best, birds endured fairly well and also had to do with standard.

It did appear that sets along the north coastline made out the most effective though (typical brood dimension of 3.7), complied with by Reptile and also
Penwith (3.4 ), main Cornwall (3.0 ), whilst those in the eastern of the region endured
most in the completely dry climate (simply 2.3).

We proceeded our run of unusual motions too, with a non-breeding man (with a normal woman) in a recognized website in Penwith having actually been ringed as a chick in 2017 in Northumberland. This is our outermost activity to day (at 587km) and also it’ll interest see if it remains to reproduce currently.

We regretfully likewise got 3 records of ringed birds dead on the A30 throughout the year, all on the open double carriageway in between Carland Cross and also Fraddon. Together with a bird that needed to be placed to rest after coming to be twisted in a barrbed cord fencing, this was an inadequate year for our chicks.
