I go with the Buzzard, thankfully more widespread now. Red Kites still tend to be West Country or Wales, Buzzards and Kestrels are common, Hen Harriers up here in East Anglia. Did get to see a Golden Eagle above Coniston a few years back, and one in Scotland last year. Sea Eagle at Portree on Skye as well.

Judging by your handle, you live near Woodbridge, lucky sod, I’ve never seen Hen Harriers in East Anglia, where do they hang out then. Marsh Harriers as you probably know are always a fantastic sight at Minsmere and I’ve even seen one well inland in the Stour Valley north of Colchester.
I once saw a Red Squirel in Rendelsham Forest, but my recent attempts at seeing one have come to nought, do they still live there or did the destruction of the forest in the hurricane of 87 drive them away.
My greatest ever sighting in Minsmere was during a visit to the Eels Foot pub one evening, during one of our continously frustrating walks along the levels to spot an otter, we came apon a sluice that was literally crawling with eels, not just in the water, but all over the bank, did I have my camera with me, of course not, an incredible sight.
A bird of prey that does seem to have become fairly common in these parts is the Sparrow Hawk, on Xmas Day we were round at the in-laws when one took a blue tit off the bird table in front of us and proceeded to eat it on the branch of their Horse Chestnut tree, my youth has a great picture of this taken with his mobile phone, but how do I download it.
We are fortunate in having a wild river setting at the bottom of the garden, despite living on the edge of Braintree, the bird and wild life around here is fantastic, the other night our dogs were having a row with the local fox over the fence, it was quite something, he eventually retorted by having a dump on the front lawn, I love foxes, I’ve noticed a considerable number of them dead on the roadside recently, it upsets me a lot, how can these scumbags want to hunt them down and kill them, or am I moving into dangerous territory here, as usual.
