Provide artificial nesting sites for burrow-nesting seabirds
A replicated trial on an island in Washington State, USA, in 1989-91 (Wilson 1993), found that rhinoceros auklets Cerorhinca monocerata used an average of 91% of 40 artificial burrows provided, with 58% of burrows (64% of occupied burrows) producing chicks. There were no differences in use or productivity between burrows in areas occupied by glaucous-winged gulls Larus glaucescens and those without gulls. Artificial burrows were of the same design as in Wilson 1986, with 20 spread over approximately 300 m of cliff.
