Close your eyes and let’s take a little trip today, from one landscape to another, discovering new birds calling in the wild. Particular birds are tied to their particular habitats. As these natural places go, so go the birds.
Thanks to radio transmitters, scientists have vastly increased their knowledge of Red Knot migration patterns. For example, the vast majority of Red Knots on the Pacific Coast rely on a small number of places to rest and feed during spring migration from Mexico to the Arctic. Those
A trip to the moon would mean a flight of 239,000 miles, roughly the same as circling the Earth 10 times. This Red Knot, named B95 for its band number, is nicknamed "Moonbird." Why? This male sandpiper was first banded in 1995 and spotted again -- on his migration through New Jersey -- in
Scott Weidensaul, author of Living on the Wind, says “. . . the longest, most amazing, most awe-inspiring migrations are the ones that are most delicately balanced. And if you perturb any of the supports on which it depends, the whole thing collapses like a house of cards.” Fortunately
Devices called geolocators are giving us new insights into how, when, and where birds migrate. They record daily changes in light levels at different latitudes and longitudes by recording the time of each sunrise and sunset. And by attaching them to migrating birds - like this Red Knot -
The Red Knot returns to the Delaware Bay each May to feed. These sandpipers are on their way to their nesting grounds in the northern Arctic and stop here to refuel - their stopover coincides with the spawning of horseshoe crabs. But beginning in the 1980s, vast numbers of the crabs were
