Location of the Hutton's shearwater (Puffinus huttoni) colony, darker shaded region south of Tarahaka Peak (2,283 m above mean sea level, black triangle), at Shearwater Stream in the Wharekiri catchment (white region to the north of the Kaikōura township) in the Seaward Kaikōura Ranges, New Zealand (42.2 o S, 173.8 o E), in relation to the local elevation (LINZ 2014), its nominal tributary of the Wharekiri watercourse (solid black lines, LINZ 2011a) and the Jordan Thrust (dashed black lines), which ruptured during the 2016 Kaikōura earthquake. Base map of New Zealand sourced from LINZ 2011b.

... rock substrate of the site of the Hutton's shearwater colony at Shearwater Stream ( Fig. 1) is a mixture of argillite and sandstone dominated sequences of Torlesse (Pahau) terrane 'greywacke' (Rattenbury et al. 2006). The headwaters of the catchment drain from the main divide of the Seaward Kaikōura Ranges, from an unnamed peak (2,414 m) and Tarahaka (2,283 m), before joining with the larger Wharekiri Stream at 1,050 m ...

... spatial heterogeneity in burrow density and burrow occupancy The following statistical analyses were carried out using the statistical software R v4.0.2 (R Core Table 1. Visit dates and sample sizes used to measure breeding success of Hutton's shearwater in sub-colony 5a at Shearwater Stream (see Fig. 1). burrow density, and burrow occupancy using subcolony specific parameters. Appropriate values for burrow density and burrow occupancy were assigned to unvisited sub-colonies based on detailed descriptions provided by MM following both aerial assessment and a qualitative comparison of these sites to those where burrow density was ...
