two questions?

[skeet]

I read somewhere that if they fly straight through they can make it in from 36 to 48 hrs.....some less of course according to where they summer and winter. Most do not fly straight through..they come south a ways and feed for a while and then move on again. Geese however quite often make the flight straight through from the Ungava area to the Chesapeake area. And boy do they get up there..quite often a mile or more. No on the hummingbirds. There usually isn't an interaction between species although the Disney people would have us believe so.
