All round East witton you will find walks that take you go down to the river where you may come across dippers,and grey herons ,kingfishers ,if you go up to the moors you may see red Legged Partridge ,red grouse, pheasant,soaring buzzards cerlew and oyster catchers..Jervaulx Abbey is not far and there are tea rooms there too as well as walks that take you to the river.I have just come back from Harmby which is just up the road.If you are going by car Nosterfield's just down the road or you could visit Foxglove Covert which is based in the army barracks at Catterick .It is a bird reserve for the army but you pull up at the gates and ask to see it and they will let you in give you a pass and tell you how to get to it .there i have seen deer ,grey wagtails ,all the normal birds like chaffinches, willow tits ,just dont go at weekends as they are usually netting as they do ringing there .You could vist Royal Studley that is near Ripon as the have three diffrent kinds of Deer and its also the home of Foutains Abbey.Hope this may give you a few ideas.Good luck.
