B95 (bird)
B95 (born c.1993), nicknamed Moonbird, is a red knot celebrated for its longevity as the oldest known member of its species.
The bird, a male of the ''Calidris canutus rufa'' subspecies of the red knot (a species of shorebird in the sandpiper family), was banded in Río Grande, Tierra del Fuego, Argentina in February 1995 by Patricia González, an Argentine biologist. It has been resighted many times since then, most recently during May 2014 by González in the Canadian Arctic. It also has been recaptured at least three times—the last time in 2007 (aged approximately 14) when it was found to be "as fit as a three-year-old". It is not known how long red knots typically live.〔
==Migration==
Although more formally known as B95 (from the "B95" label on the orange band on its leg), it is nicknamed "Moonbird" because its annual migrations along the Atlantic Flyway between Tierra del Fuego and the Canadian Arctic have in total exceeded the distance to the Moon. It flies approximately a year.〔(【引用サイトリンク】url=http://news.mongabay.com/2013/0522-b95-returns.html )〕
In its migration from Tierra del Fuego, B95 stops off in Delaware Bay in the Northern Hemisphere in spring to feed on horseshoe crab eggs, before proceeding to breeding grounds on an island in the north of Hudson Bay.〔 The red knot population has declined since the 1990s because of the harvesting of Delaware Bay's horseshoe crabs for bait; hence restrictions on harvesting have been put in place.〔〔(【引用サイトリンク】url=http://articles.philly.com/2014-05-29/news/50152660_1_red-knots-shorebird-scientists-shorebird-researchers )〕 Migrating back to Tierra del Fuego in November for the Southern Hemisphere spring, red knots feed on mussels in the restinga tidal flats there.〔
