Barn Owl
I was out walking locally yesterday afternoon and watched a Barn Owl hunting in broad daylight. I took a series of shots but I liked this one framed by the hole in the wall. I live in the Yorkshire Pennines and this was above 800 feet above sea level. I mentioned the altitude because Barn Owls are typically a lowland owl as they are not good at surviving where there is prolonged snow-cover, like the uplands. So Barn Owls usually only appear on the high ground after a run of mild winters Historically Barn Owls could survive snow by feeding on rats and mice inside barns. But rodenticides and grain silos mean the food isn't as plentiful so their chance of survival in a snowy winter is less. I looked at the populations of the British owls on the BTO website www.bto.org/understanding-birds/birdfacts/find-a-species and it surprised me. Tawny is the commonest with 50,000 pairs with Barn Owl second at 9000 pairs. Perhaps the next commonest will surprise many as it is Long-eared Owl with 3900 with Little Owl close on its heels with 3600 pairs. Little Owl also surprised me as I expected it to be commoner than Barn Owl as it certainly is near me. Finally comes Short-eared Owl with a quoted population of 1410 pairs. But Short-eared is almost totally dependent on Short-tailed Voles as prey, which have population cycles. So in boom vole years Short-eared Owls can be common while after bust years they are rare.
