Ice Stories:  Peregrine Falcons in Greenland (Clip)
Running Time:
00:02:14
While hiking back from a research site near Kangerlussuaq, Greenland, Ice Stories correspondent Billy D'Andrea happened upon a Peregrine Falcon scrape. Two falcons, not too thrilled that he was passing by their cliff-side nest, began circling and screaming to chase him off. In this video, listen for the sound of Wheatears (songbirds) chirping and yipping in the foreground.

Ice Stories:  Alkenones: Natural Thermometers (Clip)
Running Time:
00:03:36
To understand how Earthís climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae.

Ice Stories:  Sandpiper Egg Swap (Clip)
Running Time:
00:03:18
Dr. Bart Kempenaers, a behavioral ecologist from the Max Planck Institiute of Ornithology in Seewiesen, Germany, and his team fashion fake Sandpiper eggs, swap them for the real ones in the nest and incubate them in their lab at BASCís (Barrow Arctic Science Consortium) new research facility. Once the hatchlings emerge, they take samples from them to determine factors such as paternity. The chicks are then returned to the nest, without the mother batting a feather.
