Banded Bird Discomfort

I know oh too well, that bird ringing/banding plays an important part in ornithology but I do look forward to a time when it is replaced by a much less intrusive technique. This Semipalmated Sandpiper I saw during the Global Shorebirds Count was clearly show signs of discomfort and sadly it was not the first banded bird I have seen showing behavior like this.  I do hope it quickly becoming a thing of the pass.
