Provide artificial nesting sites for burrow-nesting seabirds
A replicated study in 1986-95 on an island in British Columbia, Canada (Gaston 1996), found that ancient murrelets Synthliboramphus antiquus used artificial nest boxes installed in May 1986, but that it took several years for them to regularly use them (7-14% of 26 nest boxes occupied in 1987-9, with eggs laid in only a single burrow each year vs. 67% of 21 boxes occupied in 1995, at least seven rearing young). Nest boxes were 40 x 40 x 13 cm and buried 100-150 m from the sea, within an area used by approximately 5,000 ancient murrelets
