South Island 1080 bird counts
Only the nine most common species were analysed in the paper; this data file contains all species. The file contains the following columns:
- species - the name of the species for which the "cards_marked" relates to
- Area - whether the site was on the West or East Coast of NZ.
- Site - the name of the site. There were four sites, two on the East Coast and two on the West Coast
- treatment - whether 1080 was applied ("treatment") or no 1080 was applied ("control"). Of the two sites on each coast, one was treatment and one was control.
- Season - the monitoring period, which consists of the Austral season, and the year.
- Transect - the transect monitored within each site.
- Station - within each transect birds were monitored at regular intervals, termed "station" here.
- Date - date of measure. In the format dd/mm/yyyy.
- Time - time of measure (several measures were undertaken each day). Time is given in 24hr format (hh:mm).
- Observer - initials of the person undertaking the bird count.
- count - number of distinct birds of that species seen or hear within 200 m of the bird count station over a five minute period.
NB the following data columns follow Dawson & Bull (1975)
- Sun - the number of minutes of sunshine on the canopy overhead during the five minute bird count. Ranges from zero to five.
- Wind - A modified Beaufort scale of wind intensity during the five minute bird count. 0 = no wind; 1 = slight movement of branches or leaves rustle, 2 = moderate movement of branches and leaves and limbs move on trees; 3 = trees sway from side to side
- Rain - Ordinal scale of rainfall during the five minute bird count. 0 = none; 1 = dripping foliage; 2 = drizzle; 3 = light; 4 = moderate; 5 = heavy.
- Temp - Ordinal scale of temperature (estimated) during the five minute bird count. 1 = freezing ( 22 degrees C).
- Noise - Ordinal scale of ambient noise during the five minute bird count. 0 Leaves still or move without noise (Beaufort 0 and I); 1 = Leaves rustle (2); 2 = Leaves and branchlets in constant motion (3 and 4); 0 = no noise; 1 = slight noise eg small stream nearby; 2 = moderate noise eg larger stream or waterfall; 3 = loud noise e.g. helicopter.
