NFWF Grant Profile

Evaluate suitability of artificial predator-proof nest modules for ashy storm-petrels (ASSP) breeding at Santa Cruz Island, California. Project will measure the effectiveness and functionality of modules by evaluating: ASSP visitation/occupancy, the number of breeding sites, breeding success rates and by comparing abiotic data between artificial and natural sites as well as recording interactions of ravens with modules and assessing ASSP depredation rates.
