True. I was thinking of cats wandering around in daylight when birds can see them.
Peter Shute
Cats are pretty silent and are stealth hunters. Still the presence of a neighbour’s cat in our courtyard provokes furious alarm calls from nesting Blackbirds and from Red Wattlebirds with dependent young. So a cat when seen really does worry birds. And wild ferqal cats are very efficient predators.
Many years ago I recall someone writing in ‘The Bird Observer’ how they had observed a small dam in dry woodland in northern Victoria over some days. All sorts of wildlife came to drink and bathe, from tiny birds up to large kangaroos. Someone else came and parked a caravan next to the dam and tethered a very small dog, Australian terrier type outside it. It didn’t bark much, but all the time it was there, on a very hot day, no birds or animals came to the dam.
Obviously, this could affect survival of many species.

Cats tend to be pretty silent predators in general so I doubt the birds would hear them very often?
