    • Survivorship data were based on resightings of color-banded individuals (n = 151 birds in Jamaica; n = 550 birds in New Hampshire). Populations at each site were censused annually, returning marked birds were considered "resighted," and unmarked individuals were captured in mist-nets and given a unique combination of colored leg bands. Warbler abundance at both sites was stable (R. T. Holmes and T. W. Sherry, unpublished data). Sex and age ratios at both locations were comparable; about 60% of birds were male and 57% of birds were 1 year old or older. Warblers banded at the New Hampshire site have never been resighted on winter quarters, nor have birds banded at the Jamaica site been resighted in breeding areas.

    • We documented the fate of all nests found and recorded the number of young fledged annually per warbler pair (n = 488 pairs) within a 64-ha plot in New Hampshire. All nestlings were weighed and banded on day 6 after hatching, the last day to safely handle young during the 8-day nestling period without causing premature fledging. Therefore, the mass on day 6 was used as the estimate of mass at fledging. Annual mean fledgling mass was computed by first averaging mass on a per nest basis (n = 392 nests) and then averaging means for all nests per year.

    • Availability of lepidopteran larvae was quantified on biweekly censuses. A census entailed visually inspecting 8000 understory leaves on transects through the study plot and recording length of each larva present. Larval lengths were converted to biomass using length-mass regressions.

    • No banded fledglings from the 64-ha plot in New Hampshire have returned to the plot as breeding adults, nor have any been resighted on winter quarters. Thus, the relations between annual fecundity and recruitment documented here represent warbler population dynamics occurring at a larger, regional scale.

    • 1. Recapture probability was modeled as either constant or as dependent on year. We did not model age-or sex-related differences in these parameters because of small sample sizes from Jamaica. Identical but separate models were run for the Jamaica and New Hampshire populations. Model details can be found at Science Online at www.sciencemag.org/features/ data/1049756/shl.
