Some species have already started breeding, as soon as the cameras turn on, for example, you can see that the tawny owl is already sitting on an egg. “The tawny owl is an early brother, there has been an egg in their nest since the beginning of February,” says Louis van Oort of the Bird Protection. The cameras at the little owl, stork, barn owl, peregrine falcon and white-tailed eagle will also be switched on from today, but they have not yet laid eggs. “The barn owl is already busy mating, so we expect an egg to be seen there soon. Swift enthusiasts need to be a little more patient. It usually starts breeding at the end of April or the beginning of May.”
