加拿大采购需求：动物迁徙、动物行为、野生动物GPS追踪器、动物移动、节律行为、反向定位

I'm looking to source a GPS tracker designed specifically for lovebirds. Ideally, this device should provide real-time location tracking and have features that ensure the safety of these pets. It's essential that it is lightweight and can be easily attached to their harnesses. Could you provide me with details about the available models, including their features and pricing? I'm especially interested in battery life, tracking accuracy, and whether it comes with any mobile app support for ease of use. Looking forward to your prompt response so we can discuss further!
