Need help.

I have been hunting an area where I was initially seeing many deer on a consistent basis. I am hunting a funnel with many heavily traveled trails between a cron field and a bean field.

The last four times I have not seen anything. I always hunt in the evening. I am very careful not to disturb the area and to the best of my knowledge have not been seen by any of the deer in the area.

Yesterday I went into the woods and a doe was moving at 3:00PM. This is much earlier than usual. Usually I see the deer moving late in the evening as they work their way to the corn field.

Any thoughts on why I am not seeing deer. Are they moving earlier? Have they caught onto me? We have had some significant weather changes too, can that make a difference?

My concern is that I thought I would see more deer as the rut approaches, not less.

Thanks,
