Great observations Branta! Always noticed how the late season birds were always resting/sleeping in the fields. Went by one of my fields yesterday and there were about 300 birds in it (5 orange collars I could see). I would say 3/4 of the birds were sitting and feeding/resting with head tucked in. GHG decoys makes a great looking shell that is in the sleeping position. Will definitely invest in some of those for next year.
