McGILL BIRD OBSERVATORY

RECOVERIES

One of the objectives of any banding program is to recapture previously banded birds.  Often these are locally breeding, wintering, or year-round resident individuals, and their recapture provides much valuable information about longevity, site fidelity, timing of migration, and more.  However, occasionally a previously banded bird has a more exotic origin - i.e. it was banded somewhere other than where it was recaptured.  This is quite a rare event, but nonetheless, such encounters help provide us with a cumulative picture of the nature of dispersal and migration for each species.  On this page we summarize the foreign recoveries that have involved MBO.
