I just received an email from American Bird Conservancy about a program that will be showing (in selected areas) on the PBS program Nature this Sunday, February 10 titled Crash: A Tale of Two Species.

Knots, champions of shorebird migration, rely on Horseshoe Crab eggs on the shores of Delaware Bay for the energy reserves to complete the northbound leg of their migration and the first critical weeks of breeding season in the Canadian Arctic. Years of over harvesting of crabs - primarily for bait and fertilizer - have imperiled several species of shorebirds, but nothing like the 90% decline in the Red Knot population in about 10 years. Will the greed of a few humans wipe this bird from the planet forever?

(Some say the impact on the local economy from ecotourism - in the form of bird watchers - is said to far outweigh income from the crab harvest - I say let the fisherman find another job.)
