Male barn swallow phenotypic & reproductive data

Data file with maximum tail streamer length, right wing length, and tetrahedral color measures for 4 ventral patches for male barn swallows from the Czech Republic, Romania, Turkey, and Israel. Clutch initiation date is provided for all populations but Romania. There are two years of data for the potential contact zone in Turkey. Color patch codes: T=throat, R=breast, B=belly, and V=vent. Also included are rotated factors summarizing phenotypic characters which were used in analyzing divergence in phenotypes and selection pressures: [BodyBrightness], [ThroatBrightness], [Saturation], and [StreamerLength]. Age is denoted for individuals we could confidently assign to a first-year or older age-class (i.e. which we had banded as a hatchling or which was an unbanded breeder at a site where we had banded all adults the previous year.)
