Great Lakes Piping Plovers


Bird bands have been used for hundreds of years and have led to much of the bird knowledge we have today. Each of our banded Great Lakes Piping Plovers receives a USGS aluminum band with a unique 9-digit number. This number is unique to that bird and will identify it throughout its life. We also use color-band patterns to allow recognition of individuals from a distance. This makes it possible for observers in different locations to piece together information about the lives of individual birds using only binoculars, spotting scopes and digital cameras.

It is estimated that 96-98% of the Great Lakes population is banded and therefore able to be extensively monitored every year. If you’re in the Great Lakes area or somewhere on their wintering grounds, look for orange! Banded piping plovers that are part from the Great Lakes are easy to identify because orange is the unique color band identifier for this population.

Banding Chicks

Great Lakes Piping Plover chicks are banded between five and fifteen days of age. Since shorebirds are precocial (Like chickens, Piping Plover chicks begin running around, feeding themselves within hours of hatching), these chicks have well developed legs, which makes it possible for us to band them at a young age. The bands we use are made of either plastic or aluminum, which makes them extremely lightweight. 

Every sibling in a family gets the same color and arrangement of three or four bands (depending on the combination used). This is called a "brood-marker combination". There aren't enough combinations available to give every chick their own unique identifier from hatching, but by giving the chicks from the same family, or brood, the same combination we can study such things as parental success, fledging rates, and return success. We use specific colors to identify breeding areas so we can usually tell where a chick hatched. Since the number of possible brood-marker color combinations is limited we reuse them in subsequent years.

Since 2006 we have begun using additional unique identifiers on chicks. We now put a colored dot (red, blue, green, or yellow) on the orange bands. Most combinations also include a colored band with a three-digit number on it. The combination of the color of the numbered band and the number on it is unique. The colored dots are very useful in counting and identifying chicks before they leave their hatch territories, but once they fledge and leave, the color-dots don't usually give a unique identification. With the advent of high-quality digital photography and digi-scoping observers are often able to read the color-band numbers and sometimes even the number on the aluminum USGS band. We are learning a great deal more about the first years of our plovers' lives through the use of these identifying numbers and with the invaluable help of observers throughout their range.

Chicks usually have colored dots on their orange band.  These are the colors used.

Banding Adults

Once a Great Lakes Piping Plover chick becomes an adult and a breeder in the Great Lakes, they get re-banded. This time the bird gets their orange band replaced with an orange flag (we currently use flags without the numbers or letters you might see on plovers from other populations) and a new pattern of color bands that's unique to them. They retain the USGS metal band that was placed on their leg as a chick and receive two color bands below the joint on the side of the orange flag and one below the joint under the USGS band. Thus, each breeding adult gets marked in a way that distinguishes them from every other Piping Plover. Once an adult bird has their unique combo they are not captured again. Only visual observations are necessary in subsequent years. This is to reduce disturbances and interactions with the birds as much as possible. They are handled only twice in their life. Because of these brief banding encounters we can learn much about their entire life history through observations and reports of their unique band colors, and through that information take action to protect the species.

Placing color-bands on legs

The banding crew is made up of trained professionals. We also are approved and follow all Institutional Animal Care and Use Committee (IACUC) guidelines as well as hold both state and federal bird banding permits. The safety and best interest of the birds is always the first priority. We guarantee that while the act of banding may be briefly intrusive or stressful to the birds, the bands themselves do not largely impact them. Multiple studies have supported that the reproductive success, flight ability, overall well being of the bird, survival*, and more are not significantly influenced by wearing one or multiple bands.
