Hi Jacob

I didn't think that birds would be directly affected by temperature
change like turtles, alligators or other reptiles. To me, what happens to
the birds are indirect affects, caused by what's already happened to
turtles, reptiles, fish and others that are lower on the food chain or
Animal Kingdom. Two of the definitions of "skewed" are crooked or out of
position. I would say that this definition is what has happened to the life
cycles of these turtles, alligators, fish or anything else similar to them
subjected to similar conditions.
