BBS Web Site Updated
The latest Breeding Bird Survey (BBS) methods paper has just come out.
(Analysis of the North American Breeding Bird Survey Using Hierarchical
Models. 2011. John R. Sauer and William A. Link. The Auk 128(1):87-98)
The paper justifies the switch from estimating equations to hierarchical
models for the analysis of BBS trends. That publication freed John Sauer
to update the BBS web site (http://www.mbr-pwrc.usgs.gov/bbs/) with BBS
trends through 2009. You get two trends now - 1966 through 2009 and 1999
through 2009, so we get a check to see if a long-term trend is still
continuing. A great feature is that the 1966-2008 trends are available
in a comparative analysis, so you can see the differences that are
caused by switching trend analysis methods and can separate those
differences from those caused by the new years of data.
Wisconsin has a rich tradition of doing a terrific job using a suite of
volunteers to survey all of Wisconsin's 92 routes each June. In recent
year, Mark Korducki has been Wisconsin's route coordinator. Extensive
use of BBS data was made in the Breeding Bird Atlas book.
Noel Cutright, Ozaukee County (eagerly anticipating opportunity to once
again run 'my' routes this June)
