I hunt the jungles of the west coast on the ground 100% . One of the most important things I’ve learned is where ever you choose to set up, do it in the shadows. Often times you are much better off using your blind as a back drop behind you, and have it shade you, and help obscure any slight movement you make. Your silhouette is your worst enemy. Right up there with getting winded.
Getting busted in a ground blind typically happens from animals approaching from behind you, or winding you. If you are hunting creek bottoms your scent typically goes down stream. Set up below the trail crossing in the shadows. If you choose higher ground, use your blind behind you to break your silhouette.
I used one of those leafy camo curtains like you posted for turkey hunting before, and the movement of the blind spooked the birds too much, and they went wide around the blind every time. I was in an excellent spot not far from their roost, and the birds traveled heading for water every day at the crack of dawn. But… That blind changed their pattern, so I just left it up and moved to another bunch of brush 50 yards away the following day. The birds were so busy keeping an eye on that fluttering blind they walked right into me…… I had fun with that….
Good luck! Kirk
