  • Have you ever had an encounter with a sasquatch-like creature?
  1. Out of curiosity, I briefly scanned the link to the permits. I work alone but believe there is a requirement for a nurse on 'group outings', regardless if they are profit/non profit. Does anyone know what the body count is to have a nurse? Is there risk to the nurse's credentials if they are busted for being in violation of the permit requirement? Does the nurse have to know how to deal with hurt feelings?
  2. Gigantor, I listened to the Cornell file. Very wimpy. I will try to record Sooty Grouse. The Sooty Grouse went away. Possibly shot since they are good tasting game birds. Might be awhile before I find more....... like summer. I have recordings of wicked Barred Owls from my area that are different than Cornell samples. Comparing audio from different habitats is interesting and takes a lot of time.
  3. Sooty Grouse are entertaining until they call back and forth across a watershed................all night. Not to be outdone by the Barred Owls.....all night long. Those who need help identifying a 'wildlife noise' can go online to The Cornell Lab of Ornithology & Macaulay Library.
  4. I do not pay attention to wood knock type sounds in the Western Washington areas where I research. I have books about animals and birds to assist me with my animal inventory. Several bird books have been very helpful. Years ago, I was hiking up a snow covered road to do a seasonal altitude check at a track way site. I was followed by 'wood knock type' sounds coming from behind and above me. A repetition rate of 5 'knocks' was repeated with a pause between sessions. The repetition was precise and seemed mechanical in the accuracy. This followed me up the road. I could not see the emitter. Too much snow for pursuit. This happened repeatedly. When all the snow had melted, I was at my relic track way and the 'emitter' visited me. A Sooty Grouse (then a Blue Grouse) dropped out of a pine tree like a dying 'Hail Mary' pass and landed several feet away from me. Interesting bird. A game bird that is very tame. The Sooty Grouse makes a series of deep 'hoots' that are loud and can be heard about 1/2 mile away. Older bird books describe the Sooty ( Blue ) Grouse as being 'ventriloqual'. However, ventriloquism is a human entertainment term and modern texts describe the vocalizations of the Sooty Grouse as 'difficult to locate'. The 'hoots' are loud and sound like wood on wood. If I heard he Dusky Grouse when I was in Eastern Washington I was not aware of the whoot. The Dusky Grouse makes single 'whoot' when they are displaying to a female. The whoot can be heard from a mile away. If you do not have eyes on the emitter, then you are guessing. My 'inventory' research book selection covers birds, mammals, reptiles, amphibians, fishes, insects and clouds. A lot of time can be consumed trying to identify a vocalization/noise. I have vocalizations that are older than 10 years that I can't identify. FYI: Santana is the Father of Wood Knocking
  5. You may want to consider that fairly well funded groups have nothing to 'share'.
  6. Not necessarily easy LCB. I am assuming that you set your unit to 'Auto Rec' or whatever the noise activated setting is to maximize run time. A company with a selection of battery packs typically used for video is "Bescor". A large selection and a battery run time feature. Their battery packs have 4 pin XLR plugs. You would have to adapt. Also, "PowerStream" has many batteries for your pack assembling future. Do you 'bag' your recorder to protect it from weather? An interesting de-humidifier is 'Humidisorb', from Trailcampro. I buy silica type de-humidifiers from Jake's Market Place. I have Bescor and PowerStream products. You will end up with big wall warts to recharge your batteries.
  7. Still having posting problems. Test post with chart. Moon and planetary illuminance chart shows what hits Earth. Check the wavelength 555nm. Many animals like that wavelength at night. Notice that there is no light coming from Uranus. Not sure why but in that area of the Gas Giants and Ice Giants, the planetary Methane is notable. 4% planetary composition of methane is a lot. Perhaps the methane has something to do with reflectance, absorbtion and emissivity of sunlight. The chart is from Bond & Henderson, 1963. above post to be edited that I forgot Neptune as an Ice Giant that does not send light to Earth.
  8. I an having posting problems. I put the blame on Win 8.1. Some listings of articles that are interesting: Atsko website; 'How game animals see and smell. "Pupil shapes and lens optics in the eyes of terrestrial vertebrates" Tim Malmstrom and Ronald H.H. Kroger. The Journal of Experimental Biology 209,18-25 (2006). "Multifocal lenses compensate for chromatic defocus in vertebrate eyes" R.H.H. Kroger, M.C.W. Campbell, R.D.Fernald, H.- J. Wagner J Comp Physiol A (1999) 184:361-369. "Nocturnal colour vision-not as rare as we might think" Almut Kelber and Lina S.V. Roth. The Journal of Experimental Biology 209, 781-788 (2006). No animals have infrared vision. Many have thousands more sensitivity levels for nocturnal vision than humans.
  9. BigTreeWalker. Color and shape of game cams is a big problem. In the forest 'early/late' light conditions have the residents shifting their vision from scotopic--mesopic--photopic (early, reversed for late). Their best dark adapted vision shifts from greenish-blue to greenish-yellow. I believe that we can not imitate a 'biological' green color during this transition and a 'green' plastic box is way too out of place. The phony camo on game cams looks suspicious. We paint our housings grey, black and brown or put camo fabric over them.
  10. Twist Animal vision is complicated and you will have to Google the respective animals color vision. There are good articles on Deer vision at the 'Atsko' web site. Research Journals have many articles on the evolution of vision, testing of vertebrates and non-vertebrates. Some info is free & some are pay-per-download. I am a trade worker. I do not have any degrees or certifications. I might be certifiable though. I am house trained. Decades ago I had training in camera operation, black & white developing and printing and color printing. I do not watch TV or sports. I do a lot of research and have trick tools and meters. I do weird science. I try to do weird science everyday. If there was a degree program in weird science, I would be teaching. Stay tuned.
  11. BigTreeWalker. I have been busy and just saw this post. I will go through my notes and try to put something together. The above link in your post is about aquatic animals. The graphs are charting illumination with photons per square centimeter. Not much light there. I have seen a photograph of a single photon, back in the 70's. Interesting side story. Here are 2 citations that discuss cone vision: American Journal of Primatology 59:67-91 (2003), Research Article, Colors of Primate Pelage and Skin: Objective Assessment of Conspicuousness. Petroc Sumner & J.D. Mollon. Clin Exp Optom 2004; 87: 4-5: 230-238 Ecology and evolution of primate colour vision. Misha Vorobyev PhD. That will get you started. I have more references. Sometimes access to Journal articles costs money. That is the way it is. It gets spendy. I have bears looking at the camo I use to cover my game cams. I never use bear boxes.
  12. Bear. I am surprised the bear image has surfaced. I have had images of mangy bears, bears with nice fur, bears walking forward, backwards and standing. Bear with me on this on. Have you noticed that there is nothing further from Mr. Jacobs?
  13. BigTreeWalker, this thread has wandered quite a bit so I will be brief. I am not able to PM. Bond, D.S. and Henderson, F.P. (1963), The Conquest of Darkness. (AD 346297) Alexandria: Defense Documentation Center. Not on NTIS database. Google that and you will see references to journal articles concerning the light hitting earth from planets and stars. Also "The Color of Light in Forests and Its Implications". John A Endler. You did not mention the type of game cam that you use in the way of IR with red glow or filtered to non-human visible. Your raccoons are considered to be color blind but have nocturnal vision (starlight and planetary light). You did not indicate a baiting arrangement in the camera trap area. Raccoons with great smell and the ability to hear earthworms do fine in darkness. I will cut it off here. Lighting conditions and nocturnal mammalian eye structure should be in a different thread ( soon ).
  14. Game cams and the mounting hardware are difficult to conceal. First off, there is a reoccurring belief that there is infrared light at night. False. There is no, repeat no infrared light at night. We have known this since about half way through the previous century. No infrared light at night. There are no animals on this planet that have infrared vision. Not all animals have trichromatic vision like humans. We see red at the high end. Sasquatch may see red. Period. Game cams and mounting hardware can absorb smells. Olfactory signaling can be very bad for your presentation. The worst aspect is noise, both audible and electronic. Some have filter holders that slap back and forth. The loudest is the ultrasonic noise from operation and especially the capacitors during charging and release for the flash. The ultrasonic noise pattern can be considered as 'spherical projection' type. Some have LEDs that flash when you arm the camera. A mis-aligned filter over the LED board will 'leak' light. A huge problem area is with magnetic fields. Magnetic fields at the batteries are a favorite homestead area for spiders and the like. Biggest problem is the switching regulated power supply. It produces fluctuating DC and AC magnetic fields. We were advised about the power supply many years ago. Few payed attention. They are very noisy boxes. Not easy to deal with.
  15. ^^^ Excellent questions from Drew. From member emotional states to parasites. Smaller than a member, but little things may eat you up: ticks, fleas, flies, flying stinging insects. Your selection of repellents will have a toxicity factor. Jungle rot on your feet can take you out of action. Food can be a huge factor. Are you going to get MRE's? Where is your water coming from?
