Golondrinas Database - Boxes

General Guidelines

It is extremely important that we know what potential nesting locations were available to the swallow population each year. To this end, a variable in this data set will be used to substantiate the status of every box (‘USECODE’).

In the first year that a box location is discontinued, it must be included in the data set, with the appropriate code for discontinued use. That location can then be deleted from the data set in subsequent years.

All relocated boxes in Golondrinas sites must be given new numbers.

Mist net locations must also be entered here using ‘mist’ for the field ‘BOXID’. This can be done once per research site (use coordinates for approximate center of site), or for specific netting locations if these are a substantial distance from the research site

These data must be submitted each year.

Variable Name

Description, definitions, values and examples

SITEID
[txt]
Research site identifier (e.g. ‘hillbank’)
BOXID
[txt]

Box identifier - unique within each site

‘mist’ entered if mist nests used at this site, or ‘mistxx’, where ‘xx’ is a value identifying multiple netting sites uniquely.

YEAR
[int]
Four-digit year i.e. 2008
USECODE
[txt]

Code for the availability of the box during the current breeding season

  • Open= available for nesting
  • New= a new nest box location, available for nesting
  • Closed= location not available for nesting, but is not discontinued
  • Remove= location (box) removed
LAT
[double]

Latitude coordinate of box or netting site

In decimal degrees to six digits of accuracy for the fractional portion

LONG
[double]

Longitude coordinate of box or netting site

In decimal degrees to six digits of accuracy for the fractional portion

ACCURACY
[int]

Accuracy of coordinates

  • 1= topographic, by hand
  • 3= GPS (preferred method)
  • 4= low quality (street map, etc.)
  • 5= topographic, online
