Interestingly there was an article recently in our local paper on the
decline of Little Penguins on Granite Island (Victor Harbor, SA). A census
has been done during August since 2001 and as you can see the numbers have
dropped dramatically by 90% since then:
2001 1548
2002 828
2003 588
2004 No valid data
2005 622
2006 586
2007 408
2008 354
2009 166
2010 146
No definite cause has been attributed to the decline but possible reasons
are climate change (seawater temperature changes) and the penguins have to
travel further for food sources, increase in the number of NZ Fur Seals in
the area and feral animals (cats).
