IN­CU­BA­TION

Bird Watching (UK) - - Breeding -

Barn Owl clutch num­bers vary be­tween two and six eggs, de­pend­ing on the avail­abil­ity of food. They don’t wait un­til they have laid them all be­fore they start to in­cu­bate, which means there can be quite an age gap be­tween the young. This is na­ture’s contin­gency plan – in times of food short­age, the youngest can be fed to the old­est to en­sure sur­vival of the stronger birds. In years of poor weather, they of­ten have small or un­suc­cess­ful clutches, some­times lead­ing to a ‘bumper’ year af­ter­wards to make up for it.
