While I was away last weekend, one of our regular visitors phoned me with the news that two barn owl chicks had been seen in our triangular nestbox. GR8!
I had a look at midday today, and I could see two heart-shaped faces looking out, so you probably won't have to brave the midges and mosquitos at dusk to see them. They can be seen easily with binoculars, but of course a telescope would be even better.
Enjoy!
