So went up to truman lake a was running lines for catfish and as I am drowning in sweat from triple digit heat I hear this awful noise sounded good to my ears for predator hunting, at first I kinda thought someone may have been calling around the bend but then it started moving as I got to the end of the line it landed in a tree, a seagulls has anyone heard these, the sound like a yotes dream I would think squaking around..
