In 2022 our barn owl nest box was taken over by a pair of stock doves when the owls didn't visit the box for a few days. One smallish barn owl had been roosting there during daytimes pretty regularly, and wanted to continue doing so. By now the stock doves had two eggs.

One dove was sitting on the eggs when suddenly a large barn owl crashed into the box, seemingly summoned by the smaller owl, and smothered the dove briefly. Yet the barn owl did not seem to aim to harm the dove, and then flew away.

The doves did not succeed in raising their young - see video 'kestrel swoops on stock dove'. Neither did the owls breed here that year though they did in 2023.
