Imagine flying to the moon and back four to six times in one lifetime. Wisdom, a banded 62-year-old Laysan albatross, has traveled enough miles—up to 3 million—to cover those trips and still have miles to spare.
Wisdom repeats her 50,000-mile trip across the Pacific Ocean each year to the Midway Atoll to hatch a chick. She has probably raised at least 30 offspring during her lifetime, and the most recent hatchling was born in February.
This is just one of the amazing stories to come out of the U.S. Geological Survey Bird Banding Laboratory in its 93-year history.
The Lab was established in 1920 as a result of ratification of the Migratory Bird Treaty Act, and it is located at the USGS Patuxent Wildlife Research Center in Laurel, Md. BBL issues permits to band birds, provides the metal bands used by bird banders, and manages more than 72 million banding and 4.5 million band encounter records. Additionally, the Lab works closely with the U.S. Fish and Wildlife Service to develop regulations for the capture, handling, banding and marking of birds.
Bird bands provide a treasure trove of information for research as well. The information from banded and marked birds allows researchers from the USGS and other governmental agencies, related nonprofits and the academic community to gather information on dispersal and migration; behavior and social structure; life span determination; population studies; survival estimation and productivity; toxicology and disease research; and the management of more than 30 migratory game bird species.
Over time managers and researchers use this information to monitor populations, set hunting regulations, restore endangered species, study effects of environmental contaminants and address issues such as avian Influenza, bird hazards at airports and crop depredations.
Captured birds are fitted with aluminum bands that are etched with a unique code and are then released. When banded or marked birds are discovered, spotters can report them by calling 1-800-327-BAND or visiting www.reportband.gov. Some birds go through many bird bands in their lifetime. Wisdom, for example, is on her fifth band.
When a person reports a sighting, he or she will be provided with the details of when and where the bird was originally marked. A copy of the report will also be sent to the researcher who banded the bird. The USGS BBL and the Canadian Wildlife Service’s Bird Banding Office maintain the records cooperatively.
7,000 Miles in 9 Days
The success of the bird-banding program has yielded astounding results about the bar-tailed godwit, a species of shorebird. Researchers from the USGS Alaska Science Center have successfully placed satellite transmitters in the godwits, tracking them since the early 1980s. The research demonstrates that godwits are capable of migrating from Alaska to New Zealand in a single flight — a flight that covers more than 7,000 miles and takes about nine days.
The godwits complete this amazing feat each autumn, migrating between breeding and nonbreeding grounds, and they do no eat or sleep.
Generally, birds migrate to take advantage of beneficial resources such as food, nesting habitat or warmer temperatures at widely separated sites. If, unlike the godwit, they rest during their migration, they will also find refuge and food at stopover sites.
Similarly, the tiny rufous hummingbird is capable of flying great distances. A female who was banded in the winter near Tallahassee, Fla., was captured the following summer in southeast Alaska. Her flight covered more than 3,000 miles in a single spring migration, in which she stopped a number of times along the way.
Over the course of 93 years, the BBL has evolved to keep pace with the wealth of knowledge it receives, as well as technological advances. In 2008, an increased demand for banding activities led to a Federal Advisory Committee review that listed six broad goals that were broken down into 23 objectives. The BBL’s five highest objectives are to ensure a continuing and adequate supply of federally issued numeric bands; improve mechanisms managing bird band data; accommodate recapture data; ensure that bird banders are adequately trained to carry out bird-banding functions; and to encourage the development of bird-banding programs in Latin America and the Caribbean.
To achieve these goals, the BBL maintains a two-year supply of all band types, converted its banding data submission process to an entirely electronic processing system, is developing an electronic permit renewal process, and it is closely coordinating with the Mexican government to develop a Mexican bird banding program.
Another major highlight includes the digitization of 4.5 million paper and microfilm encounter records, which is a major success for the BBL. Six high school students and 3 contractors were hired to prepare the documents for digitization, a process that took nearly one year. The BBL also launched an entirely online band reporting system that may eventually allow it to move away from the toll-free telephone system also used to report bird bands.
Wisdom’s commitment to her yearly transpacific journey remains a remarkable feat that continues to rewrite the record books. The USGS Bird Banding Lab is dedicated to capturing Wisdom’s remarkable journey and to the science that leads to effective conservation of migratory birds — especially species of concern – such as the Laysan albatross.
