Not that I know of but I've often see owls perched on fence posts by the side of the road and buzzards on top of telegraph poles so I'd assume each species has its own preference and will thrive if you create the right habitat for whatever species it is that you have. I've seen the owls using the poles that support my tree guards and they're only around four and a half feet to five feet high. That is what I've been putting into the fields where I've been planting year old trees as whips (also called maidens because they've not forked yet)
I can only suggest that you get the binoculars out and do a little observation, then recreate the habitat that you see the birds using.
Will do. I know there's kestrels and something bigger, not sure what. Owls I've no idea, there must be some as there's a little copse at one side and plenty of hedgerows. I'll have to give fishing a miss one night and do a reccy.
The local buzzards also perch on anything and from time to time surprise us by flying up out of the undergrowth. Mike - don't forget to listen aswell as look. Buzzards and owls have characteristic sounds which you can find out about by googling the relevent species.
Birds of prey have differing perches depending on where they are in their hunting territory, but they prefer to be high up to take advantage of their superb eyesight. Owls, although having excellent sight, have incredible hearing and tend to perch lower to the ground which is why you often see them on fence posts. The only way to attract birds of prey is to unfortunately have a healthy supply of Voles & other Rodents to attract them in the first place.
PS. Owls ears are at different positions on their heads, which is why you often see them tilting their head when hunting. This allows any noise to arrive at their ears at slightly different times, allowing precise prey location even in the Dark, Owls....you gotta love em.
There's Barn Owls up at the Farm, I've often seen them quartering the fields beyond the lake and Kestrels. My next project then is to install some poles of various height. No fence posts to speak of as the farm has no livestock.
