Visit a Atlantic coast mudflat in August and I can almost guaranty that you'll see a Semipalmated Sandpiper. This species is one of the "peeps" - a group of very similar (in both appearance and behavior) shorebirds that scurry over the bits of mud at the margins of a continent. Semis are also likely to be found on exposed areas of large rivers or flooded grassy areas.
Despite their behavioral flexibility, semis are declining precipitously: 80% fewer in 20 years. This inspired a multi-organizational study of their movements and breeding biology. To understand movements, geolocators were placed on 192 birds on their breeding grounds in the Canadian tundra. After a year, thirty-five geolocators were recovered containing a log of coordinates recorded over their year-long exploits.
The story from one individual is remarkable. A male tagged in 2013 flew over 10,000 miles and included one flight bout 3300 miles. That's an incredible physiological feat and I'm looking forward to hearing more about this study.
