Re: Yellow wader watch

["David Geering"<>]

The question regarding differential predation of colour-dyed waders is an
interesting one.  The gut feeling is that these birds may well be subject
to higher predation.  I was wondering how best to test this as birds would
just drop out of the population with little, if any, direct evidence for
the cause or, indeed, any indication that they had perished at all.

Hugo then suggests that an analysis of recapture rates might provide the
answer.  Indeed it may and I would suggest that the AWSG should make it a
priority to have a look at the data to address the issue.  It is always
reassuring to know that what you are doing is proving important information
but also that it is not unduly affecting the animals chances of survival.
