Birds are monitored by putting a ring on their leg. The ring can then be used to identify the bird if it’s captured or seen with a telescope/binoculars/camera by someone else, or if their carcass is found. Typically it’s just a small metal ring but these days multiple colored rings can also be used, those are put into a public database that anyone can use to identify the bird and see where it has been spotted, when it was ringed, how old it is etc.

A lot of you probably already know about this one but here’s Mozillas privacy not included blog where they review smart devices/services based on how much data they collect about you. A lot of car manufacturers at the very top of the most creepy ones.
