As mentioned earlier, the purpose of the blind is to hide the raptor bander and his helpers from raptors passing through the area or checking out the lures and decoys. In addition the blind serves as a calm environment for processing the captured raptors.
To the casual observer, the lure bird and trap controls inside the blind look like a tangle of cords and strings, but are actually logically and efficiently arranged to rationally aid operation.
Note the colored cords hanging from nails inside the blind. These cords run out holes at the bottom-front of the blind and are used to manipulate the lures and trigger the bow traps (and other active traps) within the trapping station.
