6.6. Encounter lines

For each sheetful of data, following the sheet header line, and the band prefix line if present, the lines used on the body of the sheet are coded as various types of encounter lines, distinguished by their first character.

In addition to the encounter lines, we strongly recommend the liberal use of blank lines to organize the data spatially. In particular, we recommend a blank line after every group of three lines on the sheet (where there is a thicker horizontal rule), and two blank lines after every group of nine (where there is an extra-thick horizontal rule).

Here are the types of encounter lines and their characteristic first character:

N New band in the same series as the last band prefix line. See Section 6.8, “New band encounter record”.
G New band, not in the current series. See Section 6.9, “The general (G) new-band record”.
U Unbanded bird, not banded. See Section 6.10, “Unbanded encounter record”.
D Band destroyed. See Section 6.7, “Lost and destroyed bands”.
L Band destroyed. See Section 6.7, “Lost and destroyed bands”.
R Recapture of a banded bird. See Section 6.11, “Recapture record (including changed and added bands)”.
C Changed band. See Section 6.11, “Recapture record (including changed and added bands)”.
A Added band. See Section 6.11, “Recapture record (including changed and added bands)”.
S Resighting of a color-banded bird. See Section 6.11, “Recapture record (including changed and added bands)”.

The initial “R” can be omitted from recapture records. Any record that starts with a digit, space, or question mark is considered a recapture. However, in MAWS sets, because there are numerous S (resighting) records, it is good practice to explicitly enter the R.
