The evidence was so convincing - the characteristic nasal "kent" call and double raps on a tree - that Dr. Prum and Dr. Robbins withdrew their challenge.

"The thrilling new sound recordings provide clear and convincing evidence that the ivory-billed woodpecker is not extinct," Dr. Prum said in a statement.

I'm ridiculously happy about this.
