I have set my newer camera up on the same tree as the main camera and have it pointing down at right angles to the view of the other, this is to look at how many move away from the path and to catch and behaviour.
Obviously, at this time of the year, the entirety of the clips are of Grey Squirrels, although this week I did get a Badgers rear end and a Muntjac. More excitingly is the grainy few of the behind of a bird species I have only ever seen very briefly as I flush it from the undergrowth, a Woodcock. The footage isn't great, it's short and it never turns enough to show its longer beak, there is also over exposure from the IR bulbs, but you can see diagnostic black patches on the rear of the head and neck as well as patternation on the wings.
To end with we have the squabbling squirrels
