The BTO recently published its 2010 nest records data and the results revealed that the brood sizes for Barn Owls was 10.8% down compared to the average of the previous five years. In fact the data shows us that the average number of chicks per brood was the third lowest on record.

Today I came across our first breeding female of 2011. She is two years old and I had ringed her last year (second bottom picture to compare with today's bottom picture) when she was paired up with a male bird although they did not breed.
She is proudly sat with five eggs and her partner is providing well for her, as the cache of field voles awaiting consumption demonstrates.
If all goes well her chicks should be ready for us to ring in June.

Following a call from Tom at Higher Whitley I called tonight with Roy to check one of our Tawny Owl boxes. Inside were three very young birds with a good cache of food to keep them going. We have arranged to call back in a few weeks time to check upon their progress.
