As the A DC Birding Blog reports, there may be trouble again for Red Knots visiting Delaware Bay on migration, as there is a new appeal to overturn the ban on Horseshoe Crap harvesting.
Delaware Bay is the largest spawning ground for Horseshoe Crabs. Red Knots feed on the eggs of the Crabs. As Horseshoe Crabs have been harvested too intensely, the number of available eggs have become less and less and so reducing the Red Knot population.

According to this
press release by Defenders of Wildlife, the North American subspecies of the Red Knot faces extinction.

Let’s hope that the ban will stay, or it might be too late for the Red Knots in North America.
