Sometimes the researchers contact you after you submit a banded bird, and I did get a response about this one! Hatched in 2013 or earlier, banded in 2015 in Louisiana. He was somewhat off the normal migration track I guess, so the researcher contacted me to confirm my information.
I have never been so close to red knots before, so I took a lot of photos today! Unfortunately red knots are disappearing at an alarming rate and are now a federally protected threatened species.
