AUDUBON’S WOODPECKER. 
Picus Auduboni, Trudeau. 
PLATE CCLSY. — Adult. 
My talented and amiable friend Dr. James Trudeau, has described this 
species in the seventh volume of the Journal of the Academy of Natural 
Sciences of Philadelphia, where he says, “ Hunting in a wood fifteen miles 
from New Orleans, on the 26th of April, 1837, my attention was attracted 
by a very extraordinai-y note, aud after some difficulty I succeeded in getting 
possession of the bird from which it proceeded. It was very wild, running- 
on the trunks and limbs of trees with the agility peculiar to the family, 
always contriving to keep on the side of the trunk most distant from its 
pursuer- It was the species ‘here described. I have frequently examined 
the spot in hopes of getting more ; and although I have often heard its note, 
the bird has, in the very thick woods, eluded my pursuit. The sportsmen 
with whom I have spoken of it, suppose it to be a common species. It is 
probable that this curious bird, respecting which I have learned nothing 
farther, has escaped the observation of naturalists on account of its resem- 
blance to the two species already named (the Hairy and Downy Wood- 
peckers).” 
The specimen mentioned above was presented to me by its discoverer, 
my obligations to whom, on account of the honour which he has conferred 
upon me, I now gratefully acknowledge. My friend Mr. Swainson has 
also named after me a Woodpecker, procured in Louisiana, but which I 
believe to be only an immature specimen of Picus pubescent.
