The Horseshoe Crab & Shorebird Connection

(click on image for larger version)

Here's an interesting website I found from the University of Delaware Sea Grant College about Horseshoe Crabs, but Of particular interest is the section on the connection between the crabs and shorebirds:

"In the last few decades, ornithologists have discovered that the spring migration of many species of shorebirds coincides with the arrival of the horseshoe crabs in Delaware Bay. Recent bird counts of migratory shorebirds have shown alarming decreases in numbers. Like the link between shorebird migration and horseshoe crab spawning times, many think there is a corresponding link between shorebird population declines and horseshoe crab over-harvesting."

Save the Red Knot!

The rufa subspecies of the Red Knot is in danger of extinction. In the July issue of Bird Calls (American Bird Conservancy) scientists say that Red Knots stopping at the Delaware Bay has dropped from approximately 100,000 in 1989 to fewer than 15,000 in 2004.
