File List capthist.txt<br> Description The file capthist.txt contains resighting histories for 829 individually color-banded Black-legged Kittiwakes observed from 1991–1996 at the Shoup Bay colony, Alaska. Resighting histories with this format are suitable for multi-state mark-resight modeling with program MARK. Individual birds are identified by their right and left leg band colors according to the abbreviations below. Bands are listed in the order with which they appear from top to bottom on the tarsus. Commas separate bands, and dashes indicate that one band slipped on top of the other (in which case the bands are listed in alphabetical order). -- TABLE: Please see in attached file. -- Birds of known sex (F = female, M = male) are identified as is the year sex was determined. Capture history abbreviations are as follows: A = manipulated breeder (observed with eggs, eggs removed), B = unmanipulated breeder (observed with eggs, eggs not removed), C = nonbreeder (observed, but without eggs), and 0 = not observed.
