Todays Quiz

Hi folks, I have been awol for some 10 days due to an unexpected admission to Hospital. Back now and feeling `Stir` - bird - crazy. Took an image of this old fellow on my grass and would ask the following questions as a sort of quiz.

(a) What is the British title of the above?
(b) How would it`s flight pattern set it apart from a Wood Pigeon as it flew towards you.

Lastly, my feeders are now inundated by a variety of tits, goldies, green finch et`c. but my nut holders are being emptied very quickly by at least two resident grey squirrel. At £2. 49p a kilo it is getting expensive. I have purchased a anti squirrel spray that is sprayed onto the feeders for 48hrs. This spray consists of chilli pepper and is having no detrimental effect on the birds. I am awaiting an early a.m. visit from my tree rats to see if the spray has any effect.
I am resisting getting a `anti squirrel` feeder as I am sure this will affect the regular visits from my family of GSW.
Anyway - feel much better after boring you with this `post` - lol.
