Hi Heidi, one site is a quarry surrounded with open moorland and a couple of lone oak trees,a nest site they used some four years ago ,another is is a non working farm with small fields with good dry stone wall as borders ,,the other is again farmland with disused farming machinery and a load of old quary rock that got dumped...we had a regular fox that used to use a large hole in the bottom of the quarry and in winter he usd to come out as i was watching the birds come out at dusk,now this year ive not spotted it,its that 7 days were they branch out if they can get passed that they can fly to evade predators not great and its low but they can do it ....four is a great result...all sites have some form of old farm material knocking around ,i did post a shot titled .little owl enviro shot were it shows the owls territory
