Dr. Mary Jamieson, instructor of the Conservation Biology in Practice course at the University of Michigan Biological Station, took this photo of a Kirtland’s warbler on Monday, June 8. The class took a field trip to Hartwick Pines State Park in the Grayling area. The management of jack pine forests helped rescue the famously recovering bird species from extinction.
Students in the Conservation Biology in Practice class used binoculars to spot Kirtland’s warblers, one of the rarest migratory songbirds in North America, under the guidance of Dr. Dave Ewert, pictured on the left in a baseball cap in the second photo. Ewert is a senior conservation scientist with the American Bird Conservancy.
Hartwick Pines State Park is one of the last remaining old growth forests, conserved by being protected from logging during the 20th century. Many of the pines in the park are over 200 years old and preserved by the state of Michigan.
