Bird banding is used to study the movement, survival and
behavior of birds. The Bird Banding Laboratory Site has links to
the value, procedure and history of bird banding, how to report
bird bands (English & Spanish), and resources for birders. Links
to bird banding manual, banding associations, equipment and
suppliers, bibliography, band size lookup, recapture database,
bander services, aging and sexing birds, longevity records,
Canadian atlas of bird banding and other resources. Combined
with supporting research in reproductive physiology,
identification of spawning habitat, and early life history this
result provides new understanding of environmental factors that
might affect reproduction of this endangered species. Report on
the captive breeding program at Patuxent Wildlife Research
Center to help save endangered whooping cranes. Site links to
natural history information on whooping cranes, why they are
endangered, cool facts on cranes, and a photo gallery.
