Your friend needs to be smart, set the camera back up during the day, camo it with a new sim card. Place it towards your trail entrance, to see everyone walk by it. Go during the day, bring a girl if you have one, nature walk. Bring a nap sac with picnic shit in it, food, drinks, snacks, CONDOMS?!. A Bird book, binoculars. A little journal with bird sketches in it and a pencil. Nothing with grow materials, nutes, or water.
So you are just a hobbyist looking for a rare bird in you area, your a amatuer artist.
