The radioed crane pictured is 2010-05, notated as (a)g/y. That translates to aluminum over green over yellow on the right leg. Radio on the left leg. Chick banded in August, 2010 in Wood Buffalo NP.
They've been bouncing back and forth between San Jose Island and the refuge this winter.
This means that the young bird has made one very long migration and many daily jaunts with the leg hardware, which is clearly not bothering it or hampering its flight.
