WI songbirds in late July/early August -- a 2nd brood, or only one?

If you're wondering whether the species you're looking at here in WI in late July or early August is in the process of raising a 2nd brood, or if the species typically has only 1 brood, here's a list of some common WI species and the number of broods they have. Keep in mind that many species will start a 2nd clutch of eggs and raise that brood if they lose the first clutch through predation or some accident. These numbers are different for many species whose range also covers southern states, where the same species that is single-brooded in the north, may have 2 in the south:

most Neotropical flycatcher species - 1 brood
E. Phoebe - 2 broods
most swallows - 1 brood, Barn Swallow - 2 broods
Blue Jay - 1 brood
Gray Jay - 1 brood
Am. Crow and Com. Raven - 1 brood
chickadees & titmice - 1 brood
nuthatches - 1 brood
House Wren - 2 or 3
Carolina Wren - 2
Marsh Wren & Sedge Wren - 2
kinglets and gnatcatcher - 1 (GCKI may have 2)
E. Bluebird, Wood Thrush, Hermit Thrush - 2
Am. Robin - 2, sometimes 3
catbird & thrasher - 2
Cedar Waxwing - most often 1
most vireos at our latitude - 1, some exceptions
most warblers - this is still poorly-known for some species, prob. 1 (Yellow-r. Warbler, Com. Yellowthroat & Ovenbird may have 2)
grosbeaks, bunting, cardinal - 2 (cardinal may have 3!)
Dickcissel -1
Scarlet Tanager -1
E. Towhee - 2
Grasshopper, Henslow's, Vesper, Savannah, Song, Field, Chipping, and Swamp Sparrows - 2
Lark Sparrow - 1
White-throated and Lincoln's Sparrows - usually 1
both Meadowlarks - 2
Red-winged, Yellow-headed Blackbirds - 2
Brewer's Blackbird - 1
Baltimore and Orchard Orioles - 1 
Am. Goldfinch - 2, sometimes 1

two excellent bird conferences in WI this fall

It's not too soon to start planning. We sincerely hope you will strongly consider attending both of these excellent conferences this fall:

2016 State of Stopover Symposium - A Great Lakes-wide Symposium on Migratory Bird Stopover Ecology and Conservation of Stopover Habitats

This is the first region-wide conference on the stopover ecology of migratory birds.

WGLBBO and Dr. Amber Roth, coordinator of the Midwest Landbird Migration Monitoring Network, will host one of the three workshop tracks at the State of Stopover Symposium. We hope you will join us. 

2016 WBCI Annual Conference – October 27-29, 2016 (Protecting birds through action & art)

This combined WBCI and BCW conference is shaping up to be one of the most unique bird conservation meetings in years. 

These meetings will provide great opportunities for learning the latest information on bird conservation, migration ecology, and connecting with colleagues from both the Midwestern United States and Canada, and from across the country.

how citizens - and birders - can use the 2016 State of the Birds report, and take action

Many people think bird conservation actions are beyond their ability - that those actions can only be taken by agencies, non-governmental organizations, or other large entities. But here is a list of actions any individual can take:

Businesses can also play a role:

With one-third of our birds needing conservation action, we need everyone to get involved on some level. Learn about what you can do to help protect our birds!

grassland birds in northeast more affected by climate change

A new paper published in the journal Landscape Ecology looks at how birds in various habitats may respond to the effects of climate change. The authors (M.A. Jarzyna of Yale, B. Zuckerberg of UW-Madison, and A.O. Finley of Michigan State University, and W.F. Porter) conclude that birds in forest habitats may be somewhat "buffered" from climate-related effects, but that species found in open habitats, especially those that are fragmented may experience more severe effects.
The paper is published in the journal's June 2016 online edition, with the title:
Synergistic effects of climate and land cover: grassland birds are more vulnerable to climate change
