Hi Wayne and others,
As with many declining species, there are 'strongholds' where the species i=
n question holds its own or even increases, at least for a time. Congratula=
tions (or should I say condolences) on living in one such area for European=
Starlings.
In addition to better building techniques as Randy suggested I'd suggest th=
at they are impacted by a decline in naturally occurring cavities in the ar=
eas they inhabit as well and perhaps the same decline in aerial insects tha=
t is affecting House Sparrows and other birds. There is also a phenomenon (=
I'm dredging this up from a long past course in Ecology I think) which desc=
ribes the large expansion and growth of a species new to an area and then a=
decline to lower levels as time passes.
In a quick look I've found that numbers in Scotland have dropped as well.
All the best,
Lance

Subject: EXTERNAL: RE: [NatureNS] Starling Declines
Hello Ian et al.
The starlings in our area do not seem to have heard that they should be dec=
lining. at least in winter. Our Kingston Xmas Bird Count had a record high=
of 3684 in 1995, with a new record of 3883 in 2012, which jumped to 5614 i=
n 2015. Perhaps it is the decline in other species that has caused observe=
rs to pay more attention to starlings in recent years.

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.
