He suggested that this was an effect of global warning. 1) does anyone know about this study and where it was published? 2) what's been the historical range of Summer Tanagers in MD, and has there been an increase of nesters in the past decade or so? thanks, shireen -- Shireen Gonzaga Baltimore whimbrel@comcast.net ======================================================================= To leave the MDOsprey list, send e-mail to listserv@home.ease.lsoft.com with the following message in line 1: signoff mdosprey ======================================================================= =========================================================================
