Good suggestions from others.
One thing I have not seen mentioned is the possibility that the camera's
exposure metering is being fooled by backlighting. If you take photos of
a relatively small object against a bright background - usually the sky,
but anything white or pale coloured - then any reflected light meter
(all cameras and most hand-held meters) will try to some extent to meter
the sky to grey. Thus the darker object (bird, plane, whatever) will
come out very dark.
In the absence of a flash, here is what I would do: Set a high ISO speed
- try 800 or even 1600. Set camera in Av (aperture priority mode) at
f/5.6; this will give you the fastest shutter speed you can get at a
reasonable aperture. (If you have a top-end L lens with f/2.8, you may
get away with this of f/4). Then dial in say +1.5 stops of compensation
(RTFM if necessary). Take photos and see if the bird comes out
reasonably exposed. Experiment with the compensation to see if +1 or +2
gives a better result, etc.
I don't think the camera flash will do a very good job in this
circumstance, but it might be worth a try. The great beauty of a DSLR is
that you get to do all this with no wasted film cost, and with instant
feedback on the results!
