Sooty shearwater breeding survey, Kidney Island, January, 2017

In January 2017, a survey was undertaken to estimate the number of breeding sooty shearwaters on Kidney Island, the distribution of their burrows and their breeding habitat preferences.

Lineage A total of 66 study plots were randomly assigned by projecting a regular grid (cells of 50 metres) over a polygon indicating the vegetated area of the island. At each grid node a circular plot of 2.5 m radius was set out. The number of burrow entrances in each were then recorded. The minimum width and height of the entrance and presence of breeding signs (fresh tussac fibre, guano or feathers) was recorded for a random subsample of less then or equal to 5 burrows in each plot. In addition, the mean tussac height and density, soil moisure, aspect and slope were all recorded. Burrow occupancy was estimated at a subsample of 18 plots as follows: On 2017-01-17 wooden cocktail sticks were set up 10 cm inside burrows in less then or equal to 5 burrow entrances within each plot. These were then revisited every two days on the 12, 14, 16, 18, 20 of January and disturbance of the sticks recorded. Sticks were re-errected on each visit. On the last day, 2017-01-20, relative burrow depth of occupied burrows were recorded.
