Dear Robert and all,

I would also like to know uses for a GPS in relation to birding. I bought
myself one for Christmas, but still haven't gotten out to use it. I know
they can be used in nest surveys, i.e., to refind nests on successive
trips. I would think they might be used somehow in locating telemetry
birds, i.e. in population/migration studies, but I don't know. Any
information would be most welcome.
