Migration. — Yv^hile the species is resident over a very large por- 

 tion of its range, there are many areas where it is not of regular 

 occurrence throughout the year, and in other regions it may be tem- 

 porarily absent (or unnoticed) for a month or more, usually during 

 the winter season. This subject might be discussed at length, but it 

 seems desirable to limit the treatment of the migration of the marsh 

 hawk to that portion of its breeding range that is definitely north 

 of the northern limits of the winter range.
