I've not shot many reds Pete,seen falow munty and roe all close eyes and all also sort of wet their nose with the tongue also a bit of head dipping. All behaviours of utterly wild deer trying to work out what it is clicking at them. Pete these observations are mine as are the conclusions. They are not from a book and there is no science behind them,but they all do it and so regularly there has to be a tie in to a certain set of circumstances. IE me pretending to be a tree and them not quite able to work out what they can hear. IE your circumstances.
Mate normally I see both eyes close and together at that, not a wink but a blink,whether that has significance I know not,I suspect it might have????
T'other thing is your buddy has closed the eye that is on the sun side,the brow has shaded the other open eye . Maybe fella can try see you better like this?
Peter I'm a bit OCD I guess,I sort of wear camo for a pastime so if i'm chasing deer tis likely i'm head to toe glove head covered the whole shebang. . The first thing they spot is a moving human shape,the three white blobs of hands and face mean they have you a field away,lesser with those covered. They will see a standing human but it's a struggle,munty will have you first fallow next roe can be silly blind up close if one is a tree or trying to be one. So I'm a bit unsure as to reds,because I don't interact with them..... see them. watch them................. ha
try to make a piccy, at the same level as the other species. I know hand on heart the species I see, see me in slightly different ways. So logically red might differ somewhat.
how did ya make these images..... landscape or portrait??
Just thoughts Peter, god knows if any help......... could be as simple as a fly in the wrong place
I don't think anyone could give a definitive to cause of the eye being shut but there are def behaviours shared betwixt the species of deer in how they react to an image maker stood stock still
take care
