Barn owls are comparatively common. Farmers are learning to understand better their great usefulness, and at least to leave them alone. Some, indeed, do more than this, and I know of two cases where the pigeon cote in the hay-loft has been given up to them. Through the back door of one of these cotes I have been able to see at my ease the funny little round-faced hissing young ones, and I was quite surprised to find how very long it is before the fully-fledged birds turn out of the nest. My friend at Heatley was one of those who entertained the owls, and he told me that if an old bird accidentally dropped a mouse as he made his way into the loft, he never by any chance attempted to recover it. He said he used on winter evenings to see the owls fly along the eaves of the neighbouring houses and inside the roof of a hayshed close by, beating with their wings to drive out the sparrows that were roosting there, and he found the remains of a great many sparrows in their casts. A barn-owl appeared in the garden one day in May, 1899. It did all it could to hide itself in the bushes and thick Scotch firs, but in spite of its efforts the birds in the neighbourhood, led on apparently by the blackbirds, found it out again and again, and kept up a ceaseless noise and commotion as long as it was here. (I noticed that the fowls, both cocks and hens, joined in the general clamour.) In December, however, I have seen an owl fly into one of the out-houses in the middle of the day, and even sit calmly in full view on a leafless tree without attracting the least notice from any bird. The keeper tells me that brown, long-eared, and short-eared owls are all to be found in Warburton at times, brown owls nesting here regularly. Sparrow hawks come to us occasionally, but not so often as kestrels. The difference in the behaviour of small birds with regard to these two hawks is remarkable, and plainly shows that they have, as a rule, little to fear from kestrels. One November day, for instance, a sparrow hawk appeared in a tree just opposite my window, causing the greatest commotion and consternation among sparrows and all other birds. A week later a kestrel came to the same place at the same time of the day and stayed about for a considerable time, but none of the small birds took the least notice of him.
