I was having a look at the bird feeders this morning and remembering how I had seen several of the familiar species in other far flung parts of the world. Great Tit (pic 1) is a species that i have seen in many parts of Eurasia, India and the Far East. Geographical variation across it's range is highly complex (over 30 races are described in HBW) but in the UK, newtoni is the sub-species.
Tree Sparrows (pic 2) occur across the whole of Eurasia and the Orient and they have also been introduced to Pacific islands and Australasia.
Chaffinch (pic 3) is a more restricted range species occurring mainly in west Eurasia and parts of North Africa and also Macronesia (although introduced to a wider area including New Zealand). There are up to 14 races including a very distinctive form which occurs in my foreign patch- the Azores. 'Azorean Chaffinch' (winter male for comparison in pic 4) differs from the Chaffinches at Beddington in having a green mantle instead of brown, peachy underparts and face instead of rusty-red and extensive grey on the flanks and vent. There are also structural and vocalisation differences.
PS. I was ponsing about in the obs this morning and missed a Waxwing which flew southeast which I need for my Beddington list.
