Description
<p>On September 2, 2015, a Pintail Snipe Gallinago stenura was caught and released in a bird-banding operation at Lake Tofutsu in Abashiri, Hokkaido, Japan. This individual had 22 tail feathers. We checked the roots of tails and there were no missing tail feathers and no growing feathers. The length and shape of the outer tail feathers of this individual were consistent with the tail characteristics of the Pintail Snipe, and it was identified as a young bird of this species by comprehensively judging it on body measurement values for the species. In the past, one case of an individual with 22 tail feathers was found in Kagoshima prefecture, but the founding individual was reported in academic research. This paper is the second record of 22 tail feathers in Pintail Snipe and is considered to be the first academic report of this phenomenon.</p>
