It is likely that the Fall issue also will be delayed as the WSO Board searches... Read More   

It was a cold and wet month that triggered a late migration. The first big warbler waves were behind schedule this May with many areas not seeing a good flight until May 15.

Of the 30 or so nest sites I monitor, there were a total of 80 eggs under incubation at 21 sites by mid April with... Read More
