A replicated study in 1996-2001 in marl prairies in Everglades National Park, Florida, USA (Baiser et al. 2008), found that as water level was increased, predation rates on Cape Sable seaside sparrow Ammodramus maritimus mirabilis nests increased. Of 429 nests found, 210 failed whilst 219 produced at least one fledgling. Nest predation accounted for 97% of failures. Early nests had higher success (47% chance of at least one fledgling/clutch) than those initiated later (1%).
