    2500-year-old bird's nest found

    "A 2500-year-old bird's nest has been discovered on a cliff in Greenland.

    The nesting site is still continually used by gyrfalcons, the world's largest species of falcon, and is the oldest raptor nest ever recorded.


    Three other nests, each over 1000 years old, have also been found, one of which contains feathers from a bird that lived more than 600 years ago.
    However, ornithologists fear climate change may soon drive the birds from these ancient nesting sites.


    Gyrfalcons live circumpolar to the Arctic. The birds range in colour from being almost exclusively white in Greenland to usually black in Labrador in Canada.


    Like many falcons, they do not build nests out of sticks and twigs, but typically lay eggs in bowel-shaped depressions they scrape into exiting ledges or old nests made by other birds such as ravens.


    But while stick nests are often frequently damaged, preventing their repeated use, gyrfalcons will often revisit some ledges and potholes from year to year.



    To find out just how long the birds return to the same site, ornithologist Kurt Burnham of the University of Oxford, UK and colleagues decided to carbon date the guano and other debris that birds leave at various nest sites around Greenland..."

    That's pretty interesting, because of the cold dry climate, the nests were able to decay much slower or something like that. Anyhoo, pretty cool stuff.

    Makes sense. There's probably only a few really ideal places and rocks don't break down like other materials. So, they just keep reusing the same places over and over. Pretty cool.

    That's damn good stuff.

    I never would have guessed that a nest could survive that long and what is really something is that the spot is still used by what must be descendants of the old ones.


    Found this and thought it would fit in with the topic.

    Just going to link it because of this blurb on the page:
