I find it astonishing that people argue of whether feral cats are bad for birds in North America. The plethora of approaches to the feral Cat problem is not an outcome of a diversity of great ideas; it is the ugly chimera of inappropriate compromise among biased and often poorly informed stakeholders. Which would be even worse.
Well, not quite like clockwork, because this year one pair of Pied Oystercatchers on Cable Beach laid their first clutch of eggs a bit earlier than normal. This year the first clutch was laid at the end of May and this is the first time we have had eggs laid in May along Cable Beach since 2000. Pied Oystercatchers feeding alone.
We have often suspected that the Sand Goannas would steal eggs as a food source from the Pied Oystercatcher nests if they found them. The two pairs should have been close to hatching their eggs from their first clutch. The pair of Pied Oystercatchers to the north have now laid a second clutch of two more eggs.
We have been busy walking the beach and keeping an eye on our local Pied Oystercatchers and the two pairs that laid their eggs earliest for the 2018 breeding season and successfully hatched out their chicks have now lost their chicks to predation. They have only laid one egg so far and another may be laid within a day.
An empty Pied Oystercatcher nest should mean that there are now chicks and that the parents have been sitting on a clutch of two eggs for twenty eight days. Some nests had clearly been there for some time and had contained eggs until recently. Pied Oystercatcher chicks can swim, but maybe feral cats will too if they are hungry.
European Red Foxes were brought into Australia in the 1850′s for recreational hunting and soon spread rapidly. Feral cats have been able to adapt very well in Australia and have grown larger over the years and can survive in areas that you would not expect. Feral cat predation on Pied Oystercatcher eggs.
The tiercels (young Peregrines) must deal with Golden Eagles, Ravens, adult Peregrines, and foxes; they must also learn to navigate the skies and make their own kills, luckily these skills appear to be innately learned. It’s not easy. Well-researched and footnoted, these sections never feel disconnected from the more personal sections.
Rats arrived on ships and cats, foxes and rabbits were all introduced and they were all detrimental to the bird population. Foxes have also been known to take their eggs and there are now numerous local groups who endeavour to help the populations of Hooded Plovers along their local coastlines.
