insect declines and their effects


A new paper on insect declines has sparked worldwide interest:

More than 75 percent decline over 27 years in total flying insect biomass in protected areas

 http://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0185809

 And more than that, how it influences bird populations, and why we're interested: https://wglbbo.org/aerial-insectivores

more about Chimney Swifts

 
Nesting Chimney Swift: ph. USNPS, Wikim. Commons


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.)
