Hugo, we had lots of them up at the lake, and they put on quite a display when the security light came on, but no problems from them coming into the house, the nearest we got, was young owls sitting on our kitchen barn door.
Last week I spotted a Peregrine Falcon sitting on our garden fence, it stayed for awhile, until it was knocked off by an attacking Magpie,
this according to my search later is not uncommon, we also had a visit from a long nosed Bee Fly? hovering over our doorstep Buddleia.
Dark-edged bee-fly Ref Wildlife Trust
About. The dark-edged bee-fly, or 'large bee-fly', looks rather like a bumblebee, with a long, straight proboscis that it uses to feed on nectar from spring flowers, such as primroses and violets. It is on the wing in the early spring, when it can often be seen in sunny patches.
