Wisconsin Kirtland’s Warbler

2017 Breeding Season Report

October 27, 2017


The 2017 Kirtland’s warbler breeding season marked the 10th year of Kirtland’s documentation and subsequent monitoring in Wisconsin. From only 11 Kirtland’s and three nests found in Adams County in 2007 to 53 individuals and 20 total nests among Adams, Marinette and Bayfield counties in 2017, the population has grown and geographically expanded in our decade of conservation work. Kirtland’s are responding to the efforts from dedicated partners and the numbers of individuals and nests in Wisconsin continue to increase.


On May 15, 2017, the first Kirtland’s of the season was detected at the Adams County site by Ashley Hannah (UW-Madison) and Barry Benson (USDA-APHIS). Over the course of the week more Kirtland’s were found and most of the color-banded males occupied territories that they held in previous years. This year, many returning males were unbanded. This may indicate a change in population structure with older males dying and younger males occupying the majority of the male age-structure in the population. It may also indicate an increase in fledgling success since 2015, with more birds returning to the site to breed.

Spill Exercise Aims to Protect Lower Green Bay

What do piping plovers, a tanker truck filled with diesel, Lambeau Field and more than 40 local responders have in common? These elements recently came together for a spill exercise in Lower Green Bay to further protection of the Cat Island Chain, an important habitat for migratory birds including the federally endangered piping plover.


The exercise simulated the release of 5,000 gallons of diesel fuel into the Duck Creek Delta, traveling towards the Cat Island Chain. The Service was represented in the exercise’s Unified Command, directing strategies for placing more than 1,000 feet of boom and protecting sensitive resources, including nesting plovers and their chicks.

In a Race Against Extinction, Rusty Patched Bumble Bee is Listed as Endangered

Just 20 years ago, the rusty patched bumble bee was a common sight, so ordinary that it went almost unnoticed as it moved from flower to flower, collecting nectar and pollen. But the species, now balancing precariously on the brink of extinction, has become the first-ever bumble bee in the United States--and the first bee of any kind in the contiguous 48 states--to be declared endangered.


The endangered designation is made by the U.S. Fish and Wildlife Service under the Endangered Species Act for species that are in danger of becoming extinct throughout all or a portion of their range. Service Midwest Regional Director Tom Melius said, “Our top priority is to act quickly to prevent extinction of the rusty patched bumble bee. Listing the bee as endangered will help us mobilize partners and focus resources on finding ways right now to stop the decline.”
