text: 1. From a New York Times crossword puzzle buff here : Ooo...! 'n hey agin! Look at 30D (Like an ivory-billed woodpecker), RARE -- Extinct is not rare and the Lord God bird (Compephilus principalis) has not been proven to be rare (as in hens teeth, well maybe!) but more likely extinct (as in T-Rex); however, as the article states Who knows? I personally can't tell a parakeet from a vulture . 2. More discussion of plumage abnormalities is on a Birdforum thread here . A Tim Allwood post on the "wariness" hypothesis is here . 3. A Flickr photo group called "Campephilus Woodpeckers" is here .
