Does this negatively affect the way a bird flies?
How dificult is it to install on a bird without using sedatives?
How many people have tried this mounting method so far?
I have a friend who says it's dangerous. Have there been problems?
Can the bird get hung up on something?
How long can it be left on my bird?
How hard is it to remove at the end of the season or if the fit is wrong?
"Thanks for developing the backpack harness and for sending the newest version. I love it. It fits well and seems to provide an easier platform for removing the transmitter. Both my tiercels finished the duck season with 32 and 35 respectivley. The RT+ was left on the one bird the entire time without consequence. The other bird was re-transmittered every day without incident. I will leave both backpacks on during the molt. I have had both birds examined under anesthesia and there is nothing to comment on concerning the use of this mounting method on these two birds.
"The old light colored bird, LittleChief, lost 2 decks, one 7 years ago. This and the problem with electrocution is my reason for changing to the backpack.
"I am completely satisfied with the method and can think of nothing negative to say other than I have experienced a couple of birds, and have heard of at least one more, that would not accept it initially (picking and getting beak caught). Your new crimping the metal sleeve eliminates the problems of removing stitches, which was the primary fault of the old methods."

"I’ve been wanting to get all the junk off my bird’s feet for years now, even going so far as to have totally removable jesses, but I still had some issues with getting the tailmount to work for me.
It’s now happened with the TrackPack mounting method. I put it on my new female passage prairie in early January this year and fly it with just one of your ultra-reliable RT+'s. The bird is flown every day now and two months later I still haven't had the low battery indicator come on yet! I just love to entire setup.
To any skeptics out there, I say: ‘You need to try this before forming an opinion.’ I think it’s the future of how we’ll be mounting telemetry on our falconry birds in the years to come. It’s just so obvious once you start using it. Thank you Marshall!"
"I have flown my Barbary about 5 days a week since June and have never seen him pay any attention to the harness or transmitter. I have never had such negligible effects from a telemetry system, and Al Ross feels the same way, even flying a PowerMax on his Merlins! My system only weighs ten grams total including the PowerMax, which you can just barely even see in this picture here.
"By the way, I just got back from a week of hawking with Harry McElroy. He flies every day, an Aplomado one day and a Harris’ the next. Both of these hawks crash the bush constantly. The desert mesquite has thorns and is wicked. I came out bleeding every day, but his hawks have never hung up with this system. We discussed this at night and he agreed that this is now the best system!"
"My 320 gram Aplomado carries about 10 1/2 grams of harness including the 7 gram PowerMax and in the process overtakes a share of mourning dove. The dove is not a slow creature. I estimate that she travels about 20 % faster than quail that she is chasing and that too would indicate good speed using the harness.
In the field the Aplomado flew right past my left shoulder and I thought how she was free of anything that I could see. Her tail was in perfect form too."
"Nicky, my tiercel Peales, killed a Hun on his 1st flight the next morning with his new backpack you installed for me at the Canadian Meet."
"I must admit, it feels like guilty pleasure just putting on one transmitter each time out in the field, having the PowerMax on the tail and the new RT+ on the back, and then just tapping them with the magnet to turn on the two transmitters right before the flight. I just leave the RT+ on 24/7. No fight, no fuss, no bitten fingers right before the flight."
"Unfortunately I won't be able to do a long-term test on the backpack as my bird was killed by a chicken farmer. The best thing about the backpack was the ease of putting on and taking off the transmitter. Most birds do not like the tail mounts, well maybe not the tail mounts but the process of putting them on and taking them off. The worry with the fit was certainly eased by watching another bird be fitted, the hands on is the best way to go. Perhaps you could do a little video about it. The more people that have seen it done and can pass on the correct way to do it the better. You coming to the Canadian meet and going to the NAFA and CHC meet will spread the good word.
"I can't wait to get another bird to put my backpack to good use."
"I now use a backpack on both passage Merlins and it’s just great. These are birds that are flown every day and catching game. Even the smallest transmitters are an nuisance and hinderance when leg mounted on these tiny birds. Being up on the back out of the way to keep the feet free is such a great improvement. I recommend it to everybody."
"I like mine. It’s been a good idea."
"I believe this is one of the best leaps forward in terms of finding a new and safer method for putting and keeping transmitters on our birds.
"I now use it on both my Merlin and the big bird."
"I really think this will come to be another one of those innovations that we can't live without. I love my experience with it, especially this year.
"Last year my anatum's harness didn't fit quite right and she fought it. But this year, no problems, and I feel much safer with it. Skeptics just need to see it done and in use like everyone else did at the Canadian meet. Thanks again for helping so many get started. You made a lot of New Believers."
"The backpack has worked fantastically....
"It completely disappeared into her plumage the next morning after she bathed. And she flies like it doesn't exist."
"I hear some say that they’d never consider it because they’ve heard of the mortality experienced by some researchers who used harnesses with the large GPS transmitters. I can say that I don't think any falconer who uses it does so knowing he is hurting or effecting his bird in some negative way or other. Yes, fit is important but just because some early research designs might have been poorly made and fitted is no reason to judge the current style adapted for falconry. A bit like comparing the risks of the early airplane designs with those of today.
"I started pursuing this because I cared about my bird and wanted to find an alternative to leg mounting. I have now used this for nearly 3 seasons and will never go back!"
"I have a little cassini tiercel that’s on the wing all day long on sort of a 'tame hack.' He comes in at the end of the day and is put inside for the night. He’s just catching starlings and caching them in different places like a wild bird. I have a BackPack Harness on him and it’s just no problem. He is totally fit and flies around here like it not even there. It's really something."
