We have a Muntjac deer that seems to have moved in to the front garden next door.  The house is currently empty, so are not being disturbed.  I think it is a she - as not antlers.  Sorry the pictures are not very good, as they are through the window, she soon runs off at the slightest noise.
Now my neighbour over the road has said that she looks big...and maybe pregnant.....haven't spotted her today, so need to get some more photos to see if she is increasing in size!
