Is a secretary bird bigger than a andean condor?
No. They are much more slender than a condor.
The largest flying bird in the world is the Andean Condor. Argentavis magnificens was the largest bird ever to have flown EDIT: Incorrect. The Andean Condor is not the largest flying bird currently living. The Dalmatian Pelican has a bigger average wingspan and a larger average weight and is the largest flying bird currently living.
