Methods

From 1982 to 2010, data were collected on breeding territory density of land-birds with territory mapping and nest searching. The study area (36 ha) was intensively surveyed by 3-5 biologists 5-7 days per week from 15 March to 31 July annually, with daily 4-6 h censuses. The _x000c_nal territory maps for each season were determined by a combination of criteria, including counter-singing, breeding observations, nest locations, and clustering and timing of singing locations. The 7 species in this study occurred every year and represent a range of life-history strategies in the same broad guild.
