Ancient murrelet

Some ancient murrelets [[bird migration|migrate]] {{convert|8000|km|mi}} from Canada to winter near Japan and China, even though the climate is similar at the two ends. It is the only bird known to cross the whole North Pacific. They then start a return trip in February, flying four or five hours a day. Genetic evidence shows that the species originated in Asia and only recently colonized North America, so their migration takes them back to their original homeland.<ref>{{cite news|last1=Rachel David|title=Bird flies 16,000-kilometre Pacific circuit for no clear reason|url=https://www.newscientist.com/article/dn28018|work=New Scientist|date=7 August 2015}}</ref> In 2007, surveys off the [[Olympic Peninsula]] found unprecedented numbers of Ancient Murrelets with chicks, strongly implying local breeding.

Other ancient murrelets however fly south in winter as far as [[California]], and odd birds are found inland in North America, carried by autumn storms. The most remarkable record of this relatively short-distance [[Pacific]] migrant was a bird found on the island of [[Lundy]], in [[Devon]], England in the spring of 1990.<ref name=Waldon/> Even more remarkably, what was presumably the same bird returned to this [[Great Britain|British]] island for the next two springs as well.<ref name=Brown/>
