[net.rec.birds] Swans & Geese

wmartin@brl-tgr.ARPA (Will Martin ) (10/18/84)

I just ran across one of the strangest ads I've ever read; it is in a
magazine for lawn care professionals (which a local library receives but
discards each month; I pick it up for a neighbor who is a gardener) called
Weeds, Trees & Turf. This ad is on pg. 42 of the October issue.

It is an ad for swan decoys or replicas, called "Sentinel Swans", which
are advertised to "Keep the Geese Away"; they are supposed to ward off
or deter Canada Geese. Now, I like both geese and swans. I'd like to
see lots of them around everywhere (well, outside, I guess...). So I'm
not too sympathetic with the aims of people who want to scare geese away.
(They give various reasons in the ad, seemingly related to maintenance
problems caused by goose droppings and shed feathers.)

Anyway, the point of all this is: why would the sight of swans deter or
intimidate Canada Geese? (And would the sight of geese inhibit swans,
in the same way?) I suppose they occupy similar ecological niches, so they
compete in some fashion. Do swans habitually attack geese? What's the
explanation here?

St. Francis would never have approved of all this interspecies hostility...
