iband7: IBP banding data entry system

Encode recapture records on a line starting with “R”, followed by all nine digits of the band number:

Rnnnnnnnnn…

where the rest of the record is described under Section 6.13, “The encounter body section”.

The initial “R” code may be omitted for sheets containing only recapture records. In the few cases where banders place recaps on new-band sheets, be sure to use the initial “R” to distinguish that record from the new-band records.

If any digit of the band number is illegible or left blank, code it as a question mark (“?”). For example, if a bander saw that the last three digits of a band number were -376, and then the bird escaped before they could read the rest of the number, code that as “??????376”.
