I have, in the past, been advised not to use a body harness when putting a tracking device on albatrosses. I also am aware of a fatality arising from this system on a tern species. But are there examples of safe harnesses for other groups of seabirds? Is there a general view about this, or are shorter-winged seabirds (alcids?) OK to have body harnesses fitted, but albies not? Other heuristics?
I am aware of the weight issues with tracking bird, this query is specifically about body harnesses. A second, related query, is about other options for long-term attachments - if body harnesses don't work, what else has been tried/is known to be acceptable?
