  1. Provide artificial nesting sites for burrow-nesting seabirds

    A replicated controlled trial in 1992-4 on Cabbage Tree Island, New South Wales, Australia (Priddel & Carlile 1995), found that Gould’s petrel Pterofroma leucoptera leucoptera breeding success was comparable or higher in artificial burrows, compared to natural cavities (36-63% breeding success for 14-19 pairs in artificial burrows vs. 23-31% success for natural cavities in previous years). The number of birds using artificial burrows increased over time, from 53% of 90 boxes visited but no eggs laid in 1992 to 19 eggs laid, and 13 chicks fledging in 1994. Burrows consisted of a 20 × 25 × 52 cm polyethylene box, accessed through a 40 cm long tunnel of 10 cm diameter PVC piping. In 1993, many eggs rolled into the entrance tunnel, so a 4 cm barrier was added at the nest chamber entrance in 1994.
