"LAMAR, Texas — The whooping crane population has set another record with 270 of the endangered birds wintering on the Texas Coastal Bend.My earliest memories of the whooping crane were that the count was hovering around thirty. During the same time frame, the brown pelican was on the verge of extinction because DDT applications had weakened the shells of their eggs to the point where almost no young were being born.
The birds in the world's only wild flock spend each winter in the Aransas National Wildlife Refuge in Texas before returning to Canada and the Wood Buffalo National Park.
Tom Stehn, whooping crane coordinator for the U.S. Fish and Wildlife Service, said the flock size is up four from last year. The worldwide population, which includes both wild and captive birds, stood at more than 500 in September. The low for the species was 15 in 1941. ..."
The whooping crane and the brown pelican recoveries are two good examples of why environmental protection and mitigation are important.
