BULLETIN 1268, IT. S. DEPARTMENT OE AGRICTJLTUEE 



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 (f), already explained, are as follows: 

 <? , male bird; $, female; juv., young (juvenile) ; im., immature.
