It was back in July 1997 when a curious snippet that apparently featured a while earlier on the internet (possibly in the Virtual Bigfoot Conference website) was brought to my attention by English palaeontologist Dr Darren Naish. However, its mysterious claim is still unverified today, so I'm posting it here on ShukerNature in the hope that readers may be able to help me finally resolve this very curious but highly intriguing crypto-dilemma.
As far as Darren could recall, the snippet claimed that several sightings had been made, the most recent during 1975, of a 7-ft-tall bird in the Mount Adams area of Washington State, USA, and which had been likened to a giant brown bird, called the pach-an-a-ho' (variously translated as 'crooked-beak bird' or 'rough-looking bird'), from traditional Yakima legends.
In addition, a party of Native Americans apparently visited a certain American museum not long before the snippet appeared online, and became very excited when they saw a life-sized reconstruction of a giant species of flightless, putatively predatory anseriform bird from prehistoric (mid-Eocene) North America called Diatryma [aka Gastornis] giganteus, because they claimed that this was the pach-an-a-ho'.
Sources informed me that issue #20 (August 1992) of the Western Bigfoot Society's newsletter, The Track Record, may include details concerning all of this. However, in April 2010 I learnt from American cryptozoologist Chad Arment that in fact this issue does not contain any mention of such a bird.
As for Diatryma reconstructions, the only one that I am aware of in the USA was a diorama featuring two adults and a chick that was housed at the California Academy of Sciences, but it is no longer on display there.
Needless to say, I don't believe for one moment that there is a contemporary Diatryma dynasty stalking the slopes and environs of Mount Adams in scientifically-undisclosed seclusion, but the whole saga is undeniably intriguing - curiouser and curiouser, in fact, as Lewis Carroll's Wonderland-exploring Alice might well have said, had she been aware of it. Consequently, if any ShukerNature readers can shed further light upon this mystifying case, I'd greatly welcome any details.
For an extensive chapter devoted to Diatryma and other gastornithids plus the formidable phorusrhacids or terror birds, see my latest book The Menagerie of Marvels: A Third Compendium of Extraordinary Animals, to be published this coming autumn by CFZ Press, and featuring a spectacular wraparound cover by celebrated artist Anthony Wallis showcasing a pair of monstrous terror birds in all their magnificent ferocity!
