Automation has come to the world of biologists who study bird migration, taking away some of the hard labour involved in studying tiny creatures that live in treetops.

This is a happy change for York University’s Bridget Stutchbury, who has chased songbirds through forest canopies for decades.

In the old days, she would put a tiny geolocator on a bird — a device that recorded where it went. The drawback: She would send birds south with these tiny backpacks, but she had to catch them again the next spring to extract the data. That meant putting out nearly invisible nets and waiting for the bird to fly into one.
