Tiny cell phones are being used to track migrating songbirds as they make their annual treks between North and South America.   The phones will act as transmitters rather than real cell phones since birds do not have the manual dexterity to dial those small keys.   The transmitters will communicate with cell phone towers and each bird's phone will have a unique signal so specific birds' routes and destinations can be tracked.

No consideration has apparently been given in regards to what happens when birds fly into or through dead zones or places where you cannot "hear me now."   It remains unclear whether these phones are only outgoing or can receive incoming calls as well.
