Individual study: Comparison of the breeding success of collared flycatchers Ficedula albicollis nesting in nest boxes and natural cavities in Bialowieza National Park, Podlaskie, Poland

This study investigated the breeding ecology of collared flycatchers Ficedula albicollis nesting in nest boxes and natural cavities in an area of old-growth oak Quercus –lime Tilia–hornbeam Carpinus forest within Bialowieza National Park (52°41'N, 23°52'E), Podlaskie, north-eastern Poland.
During 1993–1999, active nests in boxes and natural sites were visited regularly to collect data on various reproductive parameters: first-egg laying date; clutch size; partial egg loss (the proportion of eggs that did not hatch in nests where at least one egg did); partial nestling loss (the proportion of nestlings that died before 14 days old in nests where at least on chick fledged); and the number of nestlings that fledged from successful nests (i.e. those from which at least one chick fledged). Breeding data from 1994 (when nest boxes were replaced) were excluded from analyses.
