Horseshoe Crabs and Shorebirds
The Story of a Food Web

Horseshoe Crabs and Shorebirds

What it's about
A fascinating food web story! Along the shoreline of Delaware Bay, hundreds of thousands of horseshoe crabs lay eggs at just the right time in the spring to provide food for birds migrating north. When horse- shoe crab populations dwindles, this results in a decrease in migrating birds, powerfully demonstrating the tight interconnections in this ecological system.
Kids sometimes mistakedly simplify food chains and food webs into 'bigger animals eating the smaller animals that they happen to stumble upon.' This example tackles this misconception, showing that food chains and food webs often involve precise timing and specific predator/prey relationships.
