Dear Fredt
Hans Peter Thomsen, a zoology student whom I
know well, is aPplyiag to you for a banding
permit. He wants to do a very limited amount
of banding, I think on red-winged blackbirds
only, in connection with an important
ecological study of this species. W can get
the bands from Dr. Wolfe, but should of course
have a state and federal permit before setting
traps.
I recommend that if it is at all possible
his application be approved.
Will you kindly send the proper application
blanks?
Tours sincerely,
Aldo Leopold
Professor of Wildlife Management
