"Bird-watchers love to see vagrants, or birds that have traveled far outside their range. But scientists say they have a lot to teach us in a world facing ecological change."
"From what we can tell, the Steller’s sea eagle trekking across North America does not appear homesick.
The bird has strayed thousands of miles from its native range in East Asia over the last two years, roving from the Denali Highway in Alaska down to a potential sighting South Texas before moving eastward and back north to Canada and New England. Its cartoonish yellow beak and distinctive wing coloration recently attracted crowds of rapt birders to Maine before turning up on April Fools’ Day in Nova Scotia.
“We live in a world of very little surprise,” said Nick Lund, the outreach manager for Maine Audubon and creator of The Birdist blog. Catching a glimpse of a far-flung bird in one’s backyard, he said, “is like the purest form of joy.”
But the rogue Steller’s sea eagle isn’t just a lost bird: It is an avian vagrant, a term that describes birds that wing their way well beyond their species’s normal range of movement."
