Progne problem?

Dave:
I'm not sure Black-and-white Warbler is really greatly in
trouble. I don't think it ever was a really common breeder in the
southern third of the state. Red-headed Woodpecker is a totally
different story, however. As you may know, I county list the entire
state. I use the original breeding bird atlas publication as a guide to
finding birds in summer. Red-headed Woodpecker and Purple Martin are
the two most different in their 1980s and their current distributions.
Both have obviously declined greatly. Two other which have also greatly
declined (although not as much) are Henslow's Sparrow and Ruffed Grouse.

Subject: Progne problem?
During summer 2006, I surveyed nearly all the Breeding Bird Atlas
priority blocks in Kent and Montcalm counties (about 40 blocks). Many
of these blocks contained prime sites for martin colonies, such as
inland lakes surrounded by residential areas. Most lakes had one or
more lakeside residences with apparently suitably-mounted martin housing
installed. I put in reasonable effort to document martins during my
surveys by scanning existing martin housing on accessible lakes, and
listening for their flight calls overhead at all survey points.
Although I lack knowledge of historical martin populations in the
regions I surveyed, what I observed was pretty bleak. I only recall
observing martins in around 5 of the 40 priority blocks I surveyed in
these two counties. All but 1 of the active colonies I found seemed to
be minimally maintained, with lots of House Sparrows around, etc.
While we're on the subject, I also am quite concerned about Red-headed
Woodpeckers and Black-and-white Warblers, based on my survey results for
Kent and Montcalm counties. I recall finding them in approximately 8
and 1 block(s) out of the 40, respectively.
We'll have to wait until the 2nd Atlas is published to get real
quantitative data for the entire state and all observers. By the way,
does anyone know the projected publication date?
