Controlling cats as bird predators

["michael norris" <>]

Hi Philip and all

Thanks for picking this up. Perhaps I could have stressed this, but all I 
mentioned was the value to cats of keeping them in at night.  The reason is 
that night is when most of the cat fights take place, leading to injury and 
disease.
Actually Ian Temby does mention in his book that cats are predators during 
the day as well as during the night. At night they just prey on different 
species.
Incidentally Ian works at the Victorian Department of Sustainability and 
Environment where his job is about feral and other animal problems.  A 
couple of years ago he completed a thesis on urban Silver Gulls and he used 
to contribute to Birding-Aus.  I envied his record of a Black-eared Cuckoo 
at his Melbourne home.
