  1. Reduce predation by translocating predators

    A before-and-after trial on Santa Barbara Island, California, USA (Millus et al. 2007), found that the proportion of Xantus's murrelet Synthliboramphus hypoleucus eggs predated by mice was significantly lower in 2004, when approximately 1,650 deer mice Peromyscus maniculatus elusus (endemic to the island) were translocated away from the colony, compared to the 1993-2005 average, excluding 2004 (21% of 73 eggs predated vs. an average 37% of 64). In addition, the productivity/nest was higher (1.11 vs. 0.93), but hatching success was not significantly different (56% vs. 54%).
