My apologies if any of this material has appeared before. Our mailer's
connections with Usenet have been exceedingly erratic for the past 3-4
weeks and most of the material I posted during that time got lost in the
Internet ozone.

To repost this information yet again:
The California Condor (Vultur californianus) has a wingspan of 3.05 m
(120 inches). The Andean Condor (Vultur gryphus) is the same. The latter
is probably heavier weighing in at up to 11kg (24.3 lbs).
The two largest albatrosses are the Wandering Albatross (Diomeda exulans)
and the Royal Albatross (Diomedea epomophora). Both have wingspans of
3.3 m (130 inches). The Amsterdam Albatross (Diomedea amsterdamensis) is
slightly smaller.

I'm no expert on this, however, Peter Harrison in his Field Guide to the
Seabirds of the World (1987) gives no morphometric data on the Amsterdam
Albatross and writes:
"Recently discovered species, perhaps averaging slightly smaller overall
than Wandering Albatross."
He follows Roux, J.P., Jouventin, P., Mougin, J.L., Stahl, J.C., & Weimerskirch,
H. (1983) Oiseau 53, 1:1-11 in which the preliminary accounts of
the species was published. His superb book Seabirds: An indentification Guide
(1983) which has detailed descriptions and morphometric information was
published before the Amsterdam Albatross had been described.
Perhaps some pelagic ornithologists on rec.birds have more recent information?
Other large neotropical flying birds include the Central American Jabiru (Jabiru
mycteria), a big stork standing 1.35 m (53") and weighing up to 6.5 kg. and the
splendid and unfortunately rare Harpy Eagle (Harpia harpyja). Females are 1.07 m
long and can weight up to a whopping 7.5 kg. (males are smaller,
weighing in at 4.5 kg).
The male Greater Rhea's (Rhea americana), a flightless bird which stands 1.4 m
(53") tall, can weigh in at up to 25 kg (55) lbs making it perhaps the heaviest
neotropical bird.

Thanks to Bob McKay <rim@csadfa.cs.adfa.oz.au> for pointing out that the metric
and Imperial units do not match (can't understand what happened there; it
wasn't even late at night that I was composing this post!). For the record, the
Imperial units are correct. Thus the paragraph should read:
Past eras featured some really massive birds such as Teratornis merriami
from the Pleistocene in California which had a wingspan of 3.7 m (12') or
Osteodontornis orri from the Miocence in California which had a wingspan of
more than 4.9 m (16').
In the course of ferreting around I discovered what may be a contender for the
the largest flying bird of all time. H. Howard (1952) in an article entitled:
Preghistoric Avifauna of Smith Creek Cave, Nevada, with a description of a
new gigantic raptor (Bull. So. Calif. Acad. Sci 51:50:54) formally describes
Teratornis incredibilis, a Quaternary vulture which may have had a wingspan
of 5.2 m (17') just edging out Osteodontornis orri (a toothed seabird if I
recall correctly, descibed by Howard himself later in 1957)!
Anyone else have any more massive contenders?
Cheers!

We just had a flock of four wild turkeys
wander up the driveway, past the barn,
and into the woods.
They are quite magnificent birds, and
their iridescent plumage in the morning
sunlight was very striking.

FYI, Benjamin Franklin wanted to make the Turkey our national bird instead
of the bald eagle.
