The California condor is the largest bird in North 
America and is endangered but recovering. While 
down to only a few individuals in the latter 1980's,
all of the birds were moved to captivity so that 
chicks could be raised. Re-introduced into the wild,
there are now 273 birds. In 2006, a pair of condors
were spotted near Big Sur; in 2007, a condor nest
was found in Baja California with an egg. It seems 
condors might spread throughout the West, their 
habitat before the 19th Century.
