Frank's response was, indeed, an excellent one.
I would like to point out that the same protocols apply to the
colour-marking, including the use of dyes etc, of birds. To mark the
bird/s you would require both state authority approval and approval of the
Australian Bird Banding Scheme. The reason for the latter approval is
that you don't end up using the same marking procedure that someone else
is using. Imaging how upset you would be if you were undertaking a PhD.
on the movements of oystercatchers only to find that someone else is
marking a completely different set of birds in the same manner as you are.
You would also find that to effectively dye the plumage of a bird the
beast would need to be caught first and the dye worked into the plumage.
There is a very limited range of dyes that can be effectively used on
feathers. Most simply do not last long enough to be of value.
Mind you, the type of marking you are proposing is rarely undertaken
nowadays.
Cheers
