Now here is something to crow about: These critically endangered Mariana crows, released from a captive-reared program just a few days ago, are foraging in the wild for the first time.
For more than 2 million years, the native forests on the islands of Guam and Rota were home to several thousand Mariana crows, a species found nowhere else on Earth. But over the last 60 years this species has completely disappeared from the island of Guam and rapidly declined on neighboring Rota. Today there are only about 175 left on the planet.
Researchers, using eggs collected from the wild, have now successfully raised several Mariana crows past the period of highest mortality and released them. And because Mariana pairs will generally lay another set of eggs when a nest fails, the project could double the number of broods in a year.
