Learn about Chimney Swifts this fall - go the website of the WI Chimney Swift Working Group, at http://www.wiswifts.org/videos-from-swift-night-out-events/ and see video of swifts at autumn roost locations.

Learn about Chimney Swift towers - replacements for capped chimneys: http://nc.audubon.org/news/build-your-own-chimney-swift-tower

In Wisconsin and other northern states, two things can help your tower to be more successful
a) insulation (Due to our frequently-cool spring weather, tower designs from southern states are often not sufficiently insulated. To offset this, add insulation in your tower design-and-build phase.)

b) use of playback recordings as an attractant (As with Purple Martins, starting a new colony/swift nesting site can be greatly aided by deploying a recording of swift vocalizations.)

Nighthawk watches this week Tues and Wed - Forest Beach Migratory Preserve

Join us at 6:50 pm on either or both Tuesday or Wednesday evenings (Aug29 and 30), at the Bill Cowart Memorial Raptor Watch platform, at Forest Beach Migratory Preserve. In the parking lot just south of the building, there will be a map posted at the kiosk, with the location of the raptor watch platform (for anyone who has never been here before). Large flights of nighthawks have already been seen in areas north of us, and this last week of August is usually the peak time at our location. (26 August was a good night in 2013, for example:http://futureofbirds.blogspot.com/2013/08/nighthawk-watch-aug-26-2013-forest.html). Other species already on migration may also be seen.

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.

Butterfly Count this Memorial Day weekend


Please consider joining the North American Butterfly Association!

You can participate in a butterfly count on Memorial Day weekend - The NABA Memorial Day Count (in the United States) will be held May 27-29, 2017.

All you need to do is to observe butterflies at one or more of your favorite butterflying localities (such as your own backyard) this coming Memorial Day weekend and note what butterflies you’ve seen. There are no requirements regarding how much time or area you cover.

Then go to the NABA web site, www.naba.org, and from there to the Recent Sightings (sightings.naba.org) web page and enter your report, filling in the location, date, and butterflies seen.


Our good friend Mike Reese is a coordinator for these counts. See his website and contact him at https://wisconsinbutterflies.org/

Red-headed Woodpecker population status

Red-headed Woodpecker population numbers continue to decline, but some local populations have rebounded a bit.

Here is the BBS trend graph for the Prairie Hardwood Transition Bird Conservation Region (southern WI is in this zone):
Here is the trend graph for Wisconsin alone:


 These two graphs look very similar. They point to continuing long-term decline.


Birders see a few individuals here and there, and there are some very localized increases. That provides very little real information about their population as a whole, but the expanding use of eBird, and the unfolding Wisconsin Breeding Bird Atlas II will gradually fill out this picture. The decline is occurring in many areas of their geographic range, including but not limited to Wisconsin.

Here are some articles with much more information:
