Cycling To Work Bird List

I cycle just over 1 mile to work every morning. Through the town, past the racecourse and into open countryside. A very rural setting of fields, hedgerows and mature trees here and there. I also pass over a small river..the Cod Beck.

So far, since I started to remember what i'd seen, I have sighted the following species...

Grey Heron (feeding in flooded field)

Mute Swan

Greylag Goose

Canada Goose

Mallard

Sparrowhawk (being mobbed by jackdaws and chaffinch)

Pheasant

Grey Partridge

Moorhen

Lapwing

Herring Gull

Common Gull

Black Headed Gull

Wood Pigeon

Collared Dove

Skylark (performing it's classic display song...towering until invisible before dropping like a stone whilst singing loudly)

Pied Wagtail

Wren

Dunnock

Robin

Song Thrush (rescued juv' from main road)

Redwing

Fieldfare

Blackbird

Great Tit

Blue Tit

Long Tailed Tit (highlighting the reported excellent breeding season of this bird...notable, roving flocks appear abundant)

Magpie

Jay (first one i've ever seen in Thirsk)

Jackdaw

Rook

Carrion Crow

Starling

House Sparrow

Tree Sparrow (good numbers of this declining bird)

Tree Sparrow (Passar montanus)

Chaffinch

Linnet

Goldfinch

Greenfinch

Bullfinch

Yellowhammer (abundant a-top hedgerows all the way along the Sand Hutton road)

Eurasian Jay (Garrulus glandarius)...another acorn for the buried winter stash.

It is estimated that a pair of Jays will bury upto 10,000 acorns in any one year. I wonder what percentage of these are eventualy eaten, if the ratio is higher in harsher winters and if the Jay can recall it's burial sites, accounting for every 'larder'?
