Abstract
Movement of tree swallows (lridoprocne bicolor) between successive breeding sites and pair bond formation was analyzed from data collected between 1965 and 1978 in central Minnesota. A lasting pair bond did not seem to exist between breeding pairs. The majority of the breeding pairs were found to separate after one year. Those that did remate usually did so in the same or an adjacent nest box. Age and reproductive success did not appear to affect whether a pair remated or divorced. Movement of the male and female the year following their mating did seem to be a factor. Males tended to have a stronger homing tendency than females. First-year swallows dispersed farther from their banding site than birds banded as adults. Two cases of inbreeding and two instances of apparent polygyny were observed.
