plural are "bigfoot" ike moose, deer, etc. and bigfoots are more of an acceptable phrase than bigfeet.
Cryptomundo » Bigfoot, Not Bigfeet! don't know if a group would be a called a herd. i would think being humanoid a group should be called a "crowd" like for people. but a group of apes are called a "shrewdness" or a "troop".
a couple of BF hunting tactics / equipment:
for a lure, i'd need an eternal out of focus camera. seems they know when your camera is on the fritz, and should be able to lure them out to taunt you.
for scouting purposes, flashy CDs hung from tree limbs (to draw in curious bigfoots to investigate the shine) with surveillance from game cameras to monitor activity on the CDs and any major game trails leading to them. this'll take 3-6 weeks, once the bigfoots realize there is no apparent danger they'll approach. perhaps build a BF nest or too around the perimeter, to further get the territorial juices flowing.
i thought of suspending fresh deer carcass or fruit over a deadfall for bait, but a bigfoot, apparently able to use their noggin, would find it peculiar that the bait was suspended and pick out the disturbance in the ground underneath. the only exception would be in cougar / mtn lion areas, the suspended bait may work and not be so out of the ordinary, and the disturbance underneath cause by creation of the deadfall may be viewed as the lion's struggle to get their kill up the tree. this'll help distract the bigfoot's attention from ground level, hopefully having them to extend their arms up (must have bait 25ft or so in the air above a game trail) exposing the vitals in centermass for a clear shot if the deadfall isn't an option.
also i imagine bigfoot is being of the thinking / predatory sort, scent control would be paramount. this rules out being too close to the bigfoot's lair. if using a rifle, .3006 or above for enough energy to get through the thick course hair, reported heavy muscle tissue, and any winter fat put on for this time of year. so i'm thinking .338 lapua running a 285gr barnes triple shock tips for good measure.
setup would have to be ridge to ridge shooting, just above the tree line using thermals and prevailing winds to the advantage of the shooter. first would be to drop a prey animal, hopefully on the sunny side of the opposing slope, and waiting for mr. B to show up. occasionally using a tree knock or two, maybe a howl or a feeding growl about every 1-2 hours to create more interest without too much commotion to give away location. the sunny slope should help to deter complete freezing of the carcass, and attract ravens / crows to feed, causing a natural dinner bell being rung for larger animals (bigfoot) to scavenge.
another theory is fresh roadkill or fruit dumped on remote road that has a high historic amount of sightings, a full tank of gas, and just drive back and forth taking the opportunity to take one with the fender. a 78 dodge power wagon with a confederate flag front license plate, empty beer cans in the back, a 8" lift kit with mud bogging tires, roll bar with big assed off road lights should be inconspicuous and blend in enough not to raise the bigfoot's suspicion.
also thought about a self contained helium balloon like a weather balloon, suspended / anchored above a bigfoot hot spot. it'd be silent, scent above the ground, used on moonless nights only. it would stick out too much during the day. this would need NV / thermal optics, probably a semi as that platform would have some motion to it a semi would be nice for quick followup shots if needed. drop down a bigfoot decoy with a remote speaker in it, silhouetted against the snow in winter to help draw that bastard out. touch off some feeding growls and small animal distress calls.
i'm thinking it would be mating season would be in august as the gestation period of a mtn ape is 8.5 months / human 9 months so it would make sense to have young the following spring when the living is good, plenty of fresh flora and fauna for the young to take advantage of or for the female to eat to provide enough milk (bigfoot decoys in the spring should be of a juvenile less than 4ft nature, creating an abandoned young feel, kicking in the mother instinct to adopt the youngster, coming out of cover to rescue it). but during mating season in august, have to use ape and human estrogen / pheromones as a lure, either for mating or territorial dominance to help draw them out. compliment that with softer "come hither" female mating calls.
another setup would be around the time livestock starts dropping their young, overwatch areas where wilderness meets ranchlands, particularly if there is a draw and stream on or close the bottomland's border. i figure bigfoots would take advantage of newborn sheep and calves, either taking them themselves, or driving off coyotes from a fresh kill they've made and taking the spoils, using the cover of the draw / streambed to mask their approach or retreat, and makes a natural ambush point.
i've thought of using salmon runs as a source, but then too much competition among bear that would gather in the same area. i think a bigfoot would win against a single black bear or grizzly, but not against multiple numbers of bear over food. i'm also thinking that while the bear are away the bigfoot will play and further pillage food sources the bear temporarily abandon for the salmon. so they should be able to be located easily in these temporary abandoned bear haunts.
so there you have it, plans are in place, just looking for sponsorship, or an opportunity to present my case on Shark Tank.
