6 BULLETIN 1268, U. S. DEPARTMENT OF AGRICULTURE 
Of death-dealing agencies, by far the most numerous are cats and 
shrikes, with squirrels of various species next. Accidents at trap- 
ping stations that may be attributed to carelessness, inexperience, 
or improperly constructed traps have been remarkably few. Natur- 
ally some accidents would occur where inexperienced persons began 
handling large numbers of small birds, caught in traps which in some 
cases were either purely experimental or crudely constructed. The 
fact that such mishaps have been so few offers abundant justification 
of the bird-banding method and shows the care and gentleness 
exercised by cooperators. Information as to the cause of the death 
of banded birds when forwarded to the Biological Survey yields 
interesting light on the subject of bird mortality and its causes 
and is thus available for study purposes. 
Symbols and abbreviations used in these tables, in addition to 
the asterisk (*) and the dagger (}), already explained, are as follows: 
¢, male bird; ¢@, female; juv., young (juvenile) ; im., immature.
