Summary
Provide artificial nesting sites for ground and tree-nesting seabirds
A study in 1997–2009 in northeast England, UK (Turner 2010) reported that a specially designed tower supported breeding kittiwakes Rissa tridactyla. The tower was erected in winter 1997/1998. It supported ≥18 occupied nests in 1998, and 131 occupied nests in 2000. The tower was moved 1 km in winter 2000/2001, but this did appear to affect nesting behaviour: it supported 112 occupied nests in 2001 and 73–143 occupied nests/year in 2002–2009. Across all years, productivity was 0.3–1.1 chicks/nest. The tower supported a three-sided, metal-framed structure with 24 wooden nesting ledges ≥10 m above ground level. Clay decoys and disused nests were placed on the ledges to attract kittiwakes. Nests and chicks were counted in summer each year from 1998.
