Asian carp spawning moves closer to Lake Michigan (Milwaukee Journal Sentinel): New evidence shows that spawning Asian carp have been found nearly 100 miles upstream from their previous spawning sites, putting them closer to Lake Michigan. Last month, President Obama introduced efforts to protect the Great Lakes from Asian carp, including upgrading electronic barriers.

Huron Pines receives grant to help fund Kirtland warbler efforts (Alpena News): Huron Pines has received a $171,000 grant to continue its work building a support network for the Kirtland’s warbler. The organization will use the funds to continue to build relationships between federal, state, regional and private partners to support the bird when it’s removed from the Endangered Species List.

Lake Erie algae bloom intensifying (ABC 13): A new report shows that the algae bloom in Lake Erie is intensifying. At Ohio’s Maumee Bay State Park, a health advisory posted at the beach indicates there are unsafe levels of bacteria in the water. This bloom is not as large as Lake Erie’s 2011 bloom, but it is larger than last year.

Speed limits affect birds’ behavior (Conservation Magazine): A new study shows that European birds fly away from cars sooner on roads with higher speed limits. The study, conducted on roads in France, observed 134 flights by birds from 21 species, mainly carrion crows, house sparrows, and common blackbirds. It was noted that the actual speed of the vehicle did not affect the birds’ flights.

Catch a close view of some iconic fish (Up North Live): On Friday, August 30, the Black River sturgeon hatchery will be offering public tours from 9 a.m. to noon. During the tours, researchers from the DNR and Michigan State University will discuss lake sturgeon biology, reproductive ecology, and research. The hatchery is located in Cheboygan County on the Upper Black River. Tours are free of charge.
