Fright, sudden chills or overexposure to hot sunlight may upset a bird
severely. When no more than fainting is involved, a few drops of water
sprinkled on the bird's head will bring it around, after which see that
it is allowed quiet, and treat it with extreme gentleness.
Under other conditions, a bird may suddenly drop off his perch,
unconscious, in the midst of a song or other normal activity. In these
cases the cause is usually quite different, and no treatment other than
correct diet can be offered. The pet may survive one or two such attacks
and live for years afterward.
