I was even more delighted when I read this sentence:
At one pregnant moment, a point-blank house finch was shown that, to everyone's astonishment, threw back its head and belted out a beautiful morning warbler song.Perfect. A typo in an article poking fun at copy-editing errors. A meta-typo. For you non-birders, t'aint no such thing as a morning warbler. Try Mourning Warbler with the easy-to-read initial caps.
