6.13. The encounter body section

The body section encodes the fields common to new-band, unbanded, and recapture records. This section has a fixed number of columns in all cases. Some optional, free-form fields may follow the body section; see Section 6.15, “The 2006 tail section: free-form addenda to the body section”.

Here is the format of the body section. Where a field is blank on the data sheet, unless otherwise indicated, code that field with space characters in the input file.

4/6 Species code. For MAPS records, use the four-letter code based on the English name; see Section 2.1, “MAPS species code authority file (2004)” or Section 2.2, “MAPS species code authority file (1998)”. For MAWS records, use the six-letter code based on the scientific name; see Section 2.3, “MAWS species code authority file”.
3 Age code and up to two how-aged codes, left-justified. See Section 4.6, “Age group”. If the entire field is blank, code “9” (unknown age) followed by two spaces.
3 Sex code and up to two how-sexed codes, left-justified. See Section 4.8, “Sex group”. If the entire field is blank, code “X” (not attempted) followed by two spaces.
1 Skull ossification code; see Section 4.9, “Skull ossification”.
1 Cloacal protuberance code; see Section 4.10, “Cloacal protuberance”.
1 Brood patch code; see Section 4.11, “Brood patch”.
1 Fat code; see Section 4.12, “Fat codes”.
1 Body molt; see Section 4.13, “Body molt”.
1 Flight feather molt; see Section 4.14, “Flight feather molt”.
1 Flight feather wear; see Section 4.15, “Flight feather wear”.
1 Juvenal plumage code; see Section 4.16, “Juvenal plumage”.
3 WRP molt cycle code; see Section 4.17, “WRP molt codes”.
8/10 Micro-aging codes. Data sheets prior to the 2004 season use eight columns, while older sheets use ten. See Section 4.18, “Micro-aging fields”.
3 Wing chord in millimeters, right-justified. If omitted, code this field as three blanks, not as zero. If fractional millimeters are given, round to the nearest whole number. See Section 4.19, “Wing”.
4 Body mass in decigrams, right-justified. There is an implied decimal before the last column, so a weight of 123.4 would be coded as “1234”. See Section 4.20, “Body mass”.
1 Status abbreviation. Although this field has three digits in its output form, only a handful of codes are in actual use, so we use a single-character abbreviation that will be translated to the final three-digit value. See Section 4.21, “Status code”.
4 Date as mmdd; see Section 4.22, “Date”. Required.
3 Capture time in the form hhm, where m is the tens digit of the minutes. See Section 4.23, “Capture time”. May be left blank.

For multi-station data sets, enter the four-letter station code; it is required in that case. See Section 4.24, “Station”.

For single-station data sets, omit this field. The station number will be inferred from the name of the data set; see Section 6.2, “Batch file naming scheme”.

2/4 Net code. The corresponding output field has a capacity of four, and in MAWS sets the input field is also four characters. In MAPS sets, this is currently two characters. Some independent MAPS stations may use net codes longer than two characters; if desired, we can write a variant data compiler that accepts a four-character input field. See Section 4.25, “Net”.
1 Alignment check character. Enter a period (“.”) here so that the data compiler can use this as to check that the length of all preceding fields is correct.

Following the fixed-size body section, you may encode several other optional fields in free-field format. See Section 6.15, “The 2006 tail section: free-form addenda to the body section”.
