I got a couple of good shots of two different Green Jays this morning, showing their leg bands. Both jays have a silver band on the left leg. One of them has a black band on the right leg, while the other has a green band on the right leg:
I assume it’s worth our keeping track of the banded birds we see, especially for species of interest in the shifting-breeding-range study (like the Green Jay).
Update: Dr. John Rappole commented as follows in a later email:
Silver left, Green right and Silver left, Black right were both part of a group of six birds that were captured on 30 April at 0700h near the feeders. All six are probably non-breeders (unknown sex and age with no brood patch or cloacal protuberance), probably young of the year from last year.
