Few birds are as strikingly beautiful as male puddle ducks in winter.<\/p>\n

And few are as scraggly as those same male puddle ducks in summer.<\/p>\n

That duller summer aspect\u00a0— whether you believe that it is an alternate plumage<\/a>\u00a0or a chronologically displaced\u00a0basic plumage<\/a> — has long been called “eclipse” plumage. And surprisingly enough, we know who came up with what is now\u00a0the familiar term for this “dingy garb<\/a>.”<\/p>\n

Charles Waterton certainly deserves his reputation for eccentricity. Remembered today almost exclusively for his absurdly acrimonious feud with Audubon and his slightly creepy whimsies — tall tales of saddling crocodiles, taxidermic hoaxes, that sort of thing — Waterton was also a serious\u00a0scientist and a truly undaunted explorer.<\/p>\n

One of the questions that attracted Waterton’s scientific interest was the “very remarkable change of plumage” undergone by male ducks<\/a> at the end of the breeding season.<\/p>\n

All speculation on the part of the ornithologist is utterly confounded [by] the strange phenomenon…. [that]\u00a0the drake, for a very short period of the year, should be so completely clothed in the raiment of the female that it requires a keen and penetrating eye to distinguish the one from the other.<\/p><\/blockquote>\n

Waterton refused to be confounded. Capturing two wild mallard drakes, he observed their plumage every day from mid-May to mid-October. To his satisfaction, he discovered that it was the dropping and regrowing of plumage\u00a0— molt — rather than any simple alteration in the color of the feathers that was behind the odd fact that<\/p>\n

once every year, for a very short period, the drake goes, as it were, into an eclipse [of] that plumage which, at all other seasons of the year, is so remarkably splendid and diversified.<\/p><\/blockquote>\n

\nIt took a while for Waterton’s felicitous coinage to catch on. Once praised by Alfred Newton in his great\u00a0Dictionary<\/em>, though, the term immediately became the standard, and we use it today without even pausing to think that someone, sometime, had to invent it.<\/p>\n
