Great Lakes Piping Plovers
Salvage Captive Rearing

Each season Piping Plover monitors are trained to recognize and watch for the signs that a nest will likely be abandoned. Unfortunately some nests are inevitably abandoned each season, most often when an adult plover is taken by a predator or when high water washes out a nest. When a monitor suspects that a nest has been, or will soon be abandoned, they get in contact with their supervisors and follow a specific protocol that details when eggs should be taken from the nest. Once a decision is made to rescue the eggs, they are transported to the University of Michigan Biological Station near Pellston, MI where the Detroit Zoo manages a captive rearing facility for Great Lakes Piping Plovers.

The Detroit Zoo, because of their expertise in bird care and incubation, has developed protocols to incubate abandoned eggs and then care for the chicks that hatch, until they are ready to be released back into the wild. They also oversee zookeepers from other AZA (Association of Zoos and Aquariums) institutions who spend two weeks or more of their summer caring for Piping Plover eggs and chicks.

Once the chick are able to fly well, they are released back into the wild on Great Lakes beaches. Whenever possible they are released near similarly-aged wild-reared chicks.

Many additional Great Lakes Piping Plovers, who otherwise wouldn't have survived, have joined the population because of the efforts of the Detroit Zoo and other AZA zookeepers. If you see a plover with an orange flag and a "split band" (two colors on one band), you will know you are seeing a captive-reared plover, a special part of our recovery efforts!

Release into the wild.

Captive rearing has been used in the Great Lakes as a last resort salvage effort in the event of nest abandonment since 1992. Many captive-reared individuals have bred successfully, contributing to the recovery of Great Lakes Piping Plovers. Although the post-release survival of captive-reared plovers is somewhat lower than wild chicks, fledging success among chicks in the captive-rearing program is greater than 90%, as compared with ~50% fledging success in the wild. This technique is an important tool for helping to increase the Great Lakes Piping Plover population.

One captive-rearing sucess story is that of "Little Cooper" (Of,L/OY:X,b)
