Back from brink of extinction, whooping cranes face a new threat – sea level rise

This article talks about how whooping cranes were rescued from extinction, but now they face another extinction event – their winter homes will soon be underwater.

Every winter, snow white whooping cranes wade in the shallow waters and tall marsh grasses of the Aransas National Wildlife Refuge. This area on the Texas Gulf Coast is critical habitat for these tall, regal birds, which were on the brink of extinction just a few decades ago. Today there are six hundred whooping cranes in the wild and most of them winter here. The threat is two-fold: drought threatens the supply of fresh water for these marshes, where salt and fresh water mix. If the water gets too salty, it cannot support the crabs and mussels that the cranes depend on for food. And then comes sea-level rise.
