Hi, I own several Pekin Ducks as pets. How does a leg band work and are they a gps tracker? I live on a huge lake and there is no public access to the lake so my ducks are safe. Everyone loves them since they are so pretty But at times they do not come home for dinner and I worry. I need to find a way to keep track of them.
Hi Adriana,
They are not GPS trackers. They are just aluminum metal bands, that we can stamp with your custom information. We have had a few customers buy GPS trackers and glue or tape them to our metal bands. But as far as I know, there are no GPS leg bands out there. https://atstrack.com/animal-class/avian.aspx

I could not find Wild Turkey on your list. Is there a reason its not included?
Hello!
Wild turkeys will be about a 7/8″ diameter band, or NBT size 28.
I have Pekin ducks. The measurement around an ankle (just above the foot) is snug at 2 1/8”. Some ducks measure larger. What size butt band do you recommend?
Hello,
If the circumference of the leg is 2.125 inches, then the diameter would be 17.18 mm. Our Size 22 butt-end band would be the best size at 17.48 mm.
