> To: [log in to unmask]
> For the seventh year in a row a Cerulean Warbler has arrived in the
> woods above our home on the southern end of Snake Mountain in
> Bridport/Cornwall. Here are number of males recorded during those years
> over a transect of 3200 feet from my place north to Mountain Road. Also
> given are first and last days observed.
> 2008 - 2 June 3 to June 13 (likely arrived mid-May; limited
> observation by me)
> 2009 - 3 May 21 to June 8
> 2010 - 10 May 11 to June 26 (presumed "typical" breeding year)
> 2011 - 5 May 13 to June 25 (presumed "typical" breeding year)
> 2012 - 2 May 7 to July 7 (big windstorm broke canopy branches early
> June; likely attempted second brood)
> 2013 - 1 May 10 to May 30 (unsettled behavior the entire time
> present; perhaps reflecting events of 2012)
> 2014 - 1 May 13.
> Note that a "presumed typical breeding year" is a little over six weeks,

> Nice to have them back. I wasn't so sure based upon the limited
