In no particular order ....
Both types of common pigeon - the wood pigeon and the feral pigeon (aka town pigeon or rock dove). The former had a wihite neck band, the latter an iridescent green.
One of the two common sparrow varieties - the house sparrow. I am not sure if we have had a tree sparrow, which is trying to make a comeback in this area; the jury's out because they look so similar to the house sparrow.
Robins and wrens. Quite often a pair of males, despite the fact they are so territorial.
Blackbirds, song thrushes and (more rarely) starlings. If we do get starlings, it's usually a flock of juveniles!
Greenfinches and goldfinches. Not frequent, but again usually a flock. I remember motoring into the drive last year, opened the car door, and about 20 of them suddenly exploded from a nearby bush
Great tits, blue tits, and I think I spotted a coal tit a couple of months back.
We had one balmy evening last year when a flock of house martins descended on the close after insects; tremendous flying display for about a half-hour.
Our famous yaffle (Woody the green woodpecker). A reasonably regular visitor, but only one sighting so far in 2018.
A couple of sightings of a sparrowhawk
Likes to sit on our back gate, according to our neighbour; we can't see it, but the neighbour can!
We are next to the local country park, through which flows a small river. There's a resident flock of mallards, who have visited the close on occasions, and I've also seen more than once a little egret (this is probably a winter continental migrant, although they do breed in Poole Harbour), plus a tree-creeper and a lesser spotted woodpecker.
No Ostriches ...
Bird food is a major item on the budget. We must have the fattest sparrows in Dorset .....
Cats are not so much an issue as rats here, though, Meriad - the sparrows are very messy feeders and scatter the seed widely on the ground. The pigeons hoover up the spillages, but we do have to be careful we don't attract rodents.
The blackbirds are very noisy, Woody's distinctive cackle can be heard at quite a distance, but the flippin' pigeons, who croon romantic melodies down our chimney, can be a right pain!
