We studied the nesting success of Kentucky Warblers (Oporornis formosus) and Hooded Warblers (Wilsonia citrina) in 15 bottomland hardwood forests on the Savannah River Site, South Carolina, during 1993-1994. The Mayfield success rate for Kentucky Warbler nests (N = 26) and Hooded Warblers nests (N = 33) was 34.7% and 28.7%, respectively. The daily survival rate for Kentucky Warbler nests (0.952, SE = 0.018) did not differ (P = 0.157) from that for Hooded Warbler nests (0.941, SE = 0.014). Successful Kentucky Warbler pairs fledged more (P < 0.001) young (3.7, SE = 0.2) than Hooded Warbler pairs (2.7, SE = 0.2). Hatch-year birds comprised a greater (P < 0.01) proportion of captured individuals for Kentucky Warblers (hatch-year:after-hatch-year = 2.2) than for Hooded Warblers (hatch-year:after-hatch-year = 0.4), possibly reflecting the greater number of young produced per successful nest for the former, and suggesting differences in post-fledging survival or in fledgling behavior between the species.
