With regards to the osprey question, it has always intrigued me how differently
"Australian" Ospreys behave compared to the ones common to my area in British
Columbia, Canada. My observation is that Ospreys in Australia are almost
exclusively salt water fishers, and that they frequently build their nests
relatively close to the ground. I have seen nests on large rocks etc. Here in
BC, Ospreys are almost exclusively fresh water fishers. Even those that live
close to the coast frequently fish in fresh water. They nest well above the
ground, traditionally in trees (always at the very top, with no branches above
the nest), but more recently on man-made structures such as electricity
transmission poles. Statistically, most nests in BC are between 10 and 20m
above the ground. My home is on the side of a long narrow lake; there is a
transmission line running along the edge of the lake for about 55 km. In that
stretch, between 15 and 20 pairs of Osprey nest on the poles every year. If
behaviour is a clue to species status, then Osprey is a candidate!Gary

That assumes that the aim of bird watching is somehow connected to what is a
number on a "current life list". That would be a very sad state of the
interest in birds. That approach misses out that there is not much variety
of behaviours between subspecies. So in terms of learning about birds,
regarding two subspecies as equalling interesting (if someone chooses to
call them different species) is not going to expand you knowledge of birds
very much. For example someone decided to call our Osprey the Eastern
Osprey, is it really a different creature from whatever the other Ospreys
are called that are not Eastern Ospreys?

I began to lose interest in actually going to various parts of the world
when I realised that I could increase my current life list without leaving
home just by looking at the latest world checklists. Subspecies become
species at the blink of an eye. Absurd when you consider that scientists
can't even agree what a species is.
