Lara, they explained long ago about the bands. The bands were not put there by Cornell.
Quote:
The female, nicknamed “Big Red” in honor of her alma mater, is slightly larger, with a darker head, nape and throat, and is banded on her right leg. From banding records we know she was banded in nearby Brooktondale, New York, during her first autumn in 2003, making her nearly eleven years old.
The male, named Ezra after the co-founder of Cornell University, is banded on his left leg. He’s a bit smaller and has golden-tawny feathers on his face and head, and a paler neck than the female. He is at least nine years old and was first banded in 2006 as an adult bird on Judd Falls Road near the Cornell campus.

I guess they banded them like the eagles were banded. Taken from the nest when younger, put in bags and weighed and banded. The eagles at Norfolk were banded before they could do much or even stand up. One whole day was devoted to it on the cam stream back then. Virginia biologists even put a radio on one eagle at this time to follow it as long as the thing stayed on and transmitted, to gather data on eagle ranges.
States here all have different laws and regulations about migratory birds. So banding is often done to see where they go and move around. If a bird ends up in a rehab center, it is most likely banded then.
