Subject: [Tweeters] @#$%^ starlings & population dynamics

People's emotion and concern for individual birds and other creatures have
motivated much good--conservation organizations, reserves, legislation,
wildlife rehabilitation facilities, etc.--and shouldn't be pooh-poohed.
BUT, we shouldn't ignore the realities of populations and their dynamics.
For example, when each female robin lives for several years and raises one
or more broods of four each year, all but two of her youngsters must, on
average, perish, else we'll be up to our eyeballs in robins.
Most of us share a revulsion against causing unnecessary suffering to any
living thing. However, our extreme focus on individuals rather than
populations has gotten us in to trouble, not only with starlings but in such
matters as urban goose populations that are exploding in the absence of
predators and sea lions that are decimating some salmon runs. The "public"
but humane eliminating of a few individuals has its place.
