Wireless Camera for unique project

[scottmason]

Hi,

I need some advice. I train birds of prey to fly with paragliders in Nepal and i want to mount cameras on my birds and record never before seen footage as they fly with me in the Himalayas with wild Eagles and Vultures.

I'm looking for a small wireless camera, with good resolution and good range but most importantly is very lightweight, even with the battery. I know most of them are powered by 9V batteries but these are just too big. Is there a camera out there that is powered by smaller batteries.

I hope someone can offer some advice or suggestions.

Thanks

Scott
