巴基斯坦采购需求：腿环

I'm looking for advanced tracking rings designed for real-time monitoring of birds. The primary purpose of these rings is to enable precise tracking of bird movements in their natural habitats. Therefore, I'm particularly interested in products that offer features such as GPS functionality, durable materials for outdoor use, and user-friendly access to tracking data. Additionally, it would be great to know about the battery life of these devices and how they're affected by environmental conditions. If there are options compatible with various bird sizes or specific functionalities, such as alert systems for certain behaviors, please include that info. Looking forward to your details and any recommendations on this!
