The Changing Climate of the Delaware Bay: Knot an Easy Solution

The red knot is a robin-sized shorebird with one of the longest yearly migrations, traveling as many as 9,300 miles from its Arctic breeding grounds to the tip of South America. The Delaware Bay is important for red knots during their annual migration, because they depend on the energy-rich eggs laid by nesting horseshoe crabs to gain enough weight to complete the last leg of the spring migration to their breeding grounds in the arctic tundra. Unfortunately, the red knot population has declined by more than 75 percent over the past 30 years, prompting the bird to be listed as threatened under the Endangered Species Act. One of the many threats responsible for the listing is climate change, which is expected to accelerate as temperatures continue to rise, sea levels increase, and storms become more intense and erratic.
