The fascinating debate about there being one or two Kentish Plovers at Old
Bar mostly centres around varying descriptions of plumage features.
I understand that this is only the second record of the KP for Australia?
Surely then, it is valid to question the statistical likelihood of two birds
of such a rare species independently turning up in Australia at the same
time at the same place? The answer has to be so close to zero that we can
take it to be zero.
If there are two birds, then they would have to have come together. Over
the time and distance involved, this implies a very close association
between the birds. However, by most people's observation, they would not
appear to be in such close association for most of the time at Old Bar?
Is there a reasonable explanation for this? (Being sick of the sight of
each other, or meeting new friends, is not the sort of answer I am looking
for).
