Q1

Molting and migration are costly to birds physiologically.  Are there differences in how a hummingbird prepares and performs migration versus a red-tailed hawk? What impacts do these differences have on the birds ability to migrate?

Q2

What determines how long a bird stays in any stopover location along its journey to its wintering grounds?  Which one of these factors do you feel is more influential?

Q3

Warblers tend to migrate from their breeding grounds to their wintering grounds during August and early September.  Hawks migrate between late September and November. Why are there such differences in the time it takes for the two groups to leave their breeding grounds overall and the difference in when they migrate during the year?  Basically, what are the factors influencing their migration?
