I have had cause to travel on the road from South Scarle to Eagle several times recently, the road passes along the edge of Eagle Hall Wood (it's only just in Lincolnshire) SK865655. On most occasions I have seen at least one , maximum 5 Blue Pheasants. They are called tenebrosus pheasants, they can appear to be black from a distance but if you get the light right they are deep blue or an irridescent dark green. the article that I found at
http://www.gobirding.eu/Photos/Pheasant.php suggests that they are mostly confined to Norfolk, but there is obviously a population in the area around Eagle Hall Wood.
Has anybody seen any anywhere else in the county ?
Best Wishes
