bird conservation news - inside and outside our borders

See recent news from BirdLife International at this link; and more recent news from the National Biological Information Infrastructure (NBII) at their site, here.

There's more, too, from the Association of Fish and Wildlife Agencies, at their site, here - which is a site worth checking now & then. Although this link mentions information linked here previously, it's both worth repaeating as well as worth leading you to the sitre for future reference.

shorebirds: news, info, & conservation - within & beyond our borders

See this recent news on the World Waders site, for a start.

Then, news from the International Wader Study Group is posted here.

If you're REALLY into shorebirds, become part of the IWSG listserv, by going here.

And, eBird has a page devoted to the International Shorebird Survey - see it here.

Although it is a little dated, this publication from USGS shows info on North American shorebird populations.

shrubland bird species

"According to the Breeding Bird Survey data from 1966 to 2003, 50 of 78 shrubland species are declining, and there is no trend information for 29 species." See more at this link. Plus additional information is at this link.

Our recent exchanges about bobwhites have me thinking about this group.

The partial list given at the first linked page above is dominated by western species, but some familiar WI species are on the list as well.

Along with ongoing declines, however, may be some range expansion of some shrubland species resulting from a warming climate in the upper Midwest. This summer I have already heard a few more reports than usual (for June) of White-eyed Vireo (the usual locations in Dane or Green counties, plus a report of a possible pair for the 2nd year in a row near the Ozaukee-Washington county line, and now a possible Milwaukee County bird). I had one along Milwaukee's Menomonee River in September last fall; where was that individual en route from? And this species is fairly regular not far south, in locations about 100 miles from the WI-IL border (I had them reliably near Joliet, IL, in June last year). Will we see (or mostly hear) more in future summers?

But what of the other declining species in this group: how will they fare in Wisconsin in the coming decades?

Months ago I posted on the decline of the bobwhite in Wisconsin. Here's more information from the WDNR quail survey, at this link - see especially the regression graph (Figure 2) on page 2.
