It's almost time for the autumn migration of Common Nighthawks.

We'll be seeing them moving south in the evenings in late August and into September. Occasionally they continue movements into the daytime hours as well.

Here are some resources about this iconic, but declining species:

Nighthawk Watches to start in about 26 days - Ozaaukee County

Join us to view Common Nighthawk migration at the Bill Cowart Memorial Raptor Watch platform at Forest Beach Migratory Preserve, starting in late August, and lasting through mid-September, when weather and a sufficient number of observers "line up" on the same evenings. For updates that include dates, times, directions, please e-mail wmueller@wglbbo.org

Additional information and updates will be posted along with news on our aerial insectivore activities and initiatives at  https://www.facebook.com/groups/1581381955435390/

bumblebee conservation

Over the past two decades, bee declines worldwide have drawn international attention. Managed honey bee (Apis mellifera) colonies decreased by 25% over 20 years in Europe and 59% over 58 years in North America, and many bumble bee populations in Europe and North America have gone locally extinct, resulting in dramatic range contractions. It is important to note that not all bees in all places are declining. Some populations are actually growing, and there are many more for which data are insufficient or nonexistent.

Sponsor a Species for the Wisconsin Breeding Bird Atlas II

 Learn how you can support the Atlas with a species sponsorship!
There are 40+ Wisconsin breeding species yet to be claimed through the Sponsor-a-Species program, a major source of support for the Atlas. Popular species like Northern Saw-whet Owl and Ruby-crowned Kinglet remain, and every dollar of every sponsorship helps support this important citizen science project. We’d love to see every one of our remaining species go to a good sponsorship “home” this summer.
