Provide artificial nesting sites for burrow-nesting seabirds
A replicated and controlled study in 1980-84 on an island in Washington State, USA (Wilson 1986), found that rhinoceros auklet Cerorhinca monocerata nesting success was at least as high for individuals nesting in artificial burrows as it was for those in natural burrows (50-89% of 10-20 artificial burrows producing chicks vs. an estimated 53-56% success for natural burrows). No differences in growth rates of chicks in artificial and natural burrows were detected. Burrows were plywood chambers (23 × 25 × 71 cm) with a 91 cm long, 13-15 cm diameter entrance tunnel. Chambers were buried 15 cm underground after being filled with fresh soil and arranged so entrances faced the sea.
