Thanks so much for sharing this link! Do you personally own one of these or have worked with them? How durable are these units? Wonder if the band that goes around the leg is reinforced with metal? To my understanding BOP beaks are more designed for ripping/tearing action, not so much a crushing action. A parrot beak can apply (say a large amazon, CAG or macaw?) up to around 700PSI of pressure for the largest macaw species. I am unsure the "crushing" weight of a hawk beak (looks like they use their feet and claws for crushing instead of their beak from what I can find on a quick google search), but parrots beaks are designed to crack nuts and chew out hollows in trees to build nests in. Wonder how these unit would hold up to a good chomp from a big parrot?
For anyone curious- this looks to have a minimum weight requirement of 400 grams, effective excluding all extra small, small and medium parrot species. Large species amazons, CAGs, eclectus, cockatoos and macaws would be the only parrots who would meet the specified weight requirements for this GPS unit. The unit states it weighs 8.4 grams, which anyone interested I'd love to know what an avian vet would have to say about the weight being on a parrots leg. FYI- parrot legs and hawk/falcon legs are different anatomically, with BOP legs being designed for grabbing and carrying away prey on the wing and parrot legs being significantly weaker.
This unit advertises a range of 60 miles and about 30+ hours per charge to locate your lost bird.
