Temporarily, all of the recognized people had been grabbed using a combination of baited mist nets and you may Potter traps. Everyone was banded which have serially designated material groups and you may an alternative mixture of color bands getting individual identity on the planet. Birds had been old having fun with a mixture of draw-recapture investigation and you will plumage and eyes coloration ; birds were classified because the first year or after first year breeders. Away from April 15th off each other ages, regions was basically featured each day in an effort to locate all the nesting efforts. After a colony is located, the fresh new social pair is understood, in addition to colony is tracked on nesting duration to the a great regular plan; having details look for [step 3, 43, 44]. A portion of studies used in which investigation try compiled as the part of a much bigger endeavor examining the matchmaking anywhere between women behavior, reproductive profits, and hormone profile, that are shown elsewhere [step three, eleven, 41, 45].
