Hi Bev,
It certainly sounds like they had a good nesting year but I guess it could =
also be that there has been a reduction in bird feeding or natural sources =
of food in your area and now your feeders are the 'only game in town'. Do y=
ou have any idea from past years where else House Sparrows were being seen =
in the Glace Bay area in winter or has your feeder been the only winter foo=
d source for a number of years?
The other factor that works its way into the House Sparrow picture (and man=
y other bird species as well) is winter survivability. This is what a study=
in the United Kingdom found was a big problem. House Sparrows may raise lo=
ts of young but because adult birds didn't have sufficient protein in the s=
ummer (i.e. not enough insects) to feed young, the young were not very fit,=
even though they successfully fledged from the nest, and most died when th=
e weather became harsher.
I'll be interested in hearing how your flock makes out through the winter. =
Please keep us posted.
All the best,
Lance

Hi Everybody.
Yesterday, Wednesday, there were so many House Sparrows hanging around our =
feeders and the roosting bushes, that I thought we should give them a count=
. We got as close as we could - 90+!!! I could not believe it! We usuall=
y have about 40+ House Sparrows, but 90 is definitely more than usual. Did=
they have a good nesting year? Well, if their numbers are any indication,=
I say around here they did!
