All:

I was asked by a colleague about trends in Eur. Starling, and was surprised=
 to see that they had steadily declined to about half their late 1960s popu=
lation levels throughout the N. Am. Breeding Bird Survey area, and similarl=
y locally (NS + PEI). Along with the sharper decline of House Sparrow, does=
 this indicate that our human-dominated landscapes have become inhospitable=
 to these highly tolerant immigrants?  Seems almost as scary as the decline=
s of many less immediately impacted species.
