This February 2015 video shows the adult little owl couple of the Beleef de Lente nestbox in the Netherlands.
From since the owlets hatched, now 1.565 preys have been brought in. Cockchafers, it’s no surprise anymore now, are still by far at number one with 798 individuals. In 19 days time, that is an average of 42 per day. Mice and shrews are only supplied piecemeal: 22 mice and 7 shrews. Less than one mouse and a half per day.
This past week we have seen the number of earthworms increase from 7 on June 2 to 25 yesterday.
