In an age-old pattern (think of the prodigal son in the Bible) the loudest mouth gets the attention.
In this case, he gets an article in the NYTimes announcing his retirement (plus I've seen tweets on the same subject).
Who is he? Diego, a turtle. Not just any turtle. but one of three males in an endangered species who were assigned the duty/given the opportunity to mate often with females in order to drive the numbers of the species above two digits.
He did, he performed admirably, siring about 40 percent of the 2,000 turtles in the species. He's described as having a big personality, charismatic.
It just so happens one of the two other males was firing blanks, leaving the third, the silent stalwart type, the one not seeking headlines, to sire the other 60 percent.
