BREAKING NEWS:
First Successful Loon Nesting in Southern Massachusetts in a Century

BRI announces the successful results of its long-term loon translocation and restoration project Restore the Call: A male loon chick that was translocated in 2015 from the Adirondack Park Region of New York to the Assawompsett Pond Complex (APC) in southeastern Massachusetts returned in 2018 to the region from which it fledged, and now in 2020 has formed a territorial pair, nested, and successfully hatched a chick in Fall River, Massachusetts. The identification of this loon (through color bands) marks the first confirmed nesting pair in southern Massachusetts in more than a century.

Loon Translocation

LOON TRANSLOCATION

A Summary of Methods and Strategies for the Translocation of Common Loons

Translocation involves multiple teams conducting source population surveys, capture and transport, and safely rearing the chicks. This brochure outlines the major steps to develop a viable translocation and restoration process. In addition, we document loons that have returned to their release lakes.

Methods: Translocation and Captive Rearing

Methods: Translocation and Captive Rearing

In the first phase of this project, BRI researchers developed the techniques and methodology to create a safe and replicable approach for translocation and captive rearing of loon chicks—moving them to a new lake location and confirming that they fledged from that lake.

2014-2016
During the 2014, 2015, and 2016 breeding seasons, BRI researchers, in cooperation with the Minnesota Department of Natural Resources, successfully translocated 17 chicks (five in 2014; seven in 2015; five in 2016) from the large breeding populations in northern Minnesota to unoccupied lakes south of the Twin Cities, Minnesota. Chicks translocated in the first two seasons ranged in age between 6 and 9 weeks old; those in the third season were older than 9 weeks.

2015-2017
In 2015, in collaboration with the New York State Department of Environmental Conservation and the Massachusetts Division of Fisheries & Wildlife, BRI successfully moved seven chicks from New York’s Adirondack Park to a lake in the Assawompsett Pond Complex (APC) in southeastern Massachusetts. In 2016, BRI translocated nine chicks to the APC (four from New York; five from Maine) with assistance from the Maine Department of Inland Fisheries & Wildlife. In 2017, eight chicks were translocated from Maine to Massachusetts. Overall, 24 chicks were successfully translocated to Massachusetts.

2017-2020
As of spring 2020, nine adult loons returned to the lake area in Massachusetts to which they were translocated and captive-reared, and then from which they fledged. Their return marked a major milestone in the efforts to translocate Common Loons.

BRI is proposing to translocate up to 24 more loon chicks from Maine.
