Hi Andrew and Philip,

Andrew, first I would like to apologize to you that I opened this can of worms 
with my first e-mail questioning your sighting. Since you mentioned that you 
were familiar with Manx Shearwater, I am sure that you were familiar with 
Northern Gannets, too. On the other hand your description fits best an immature 
gannet - on this side of the world most likely an Australasian Gannet. In this 
case (until proven otherwise) it was important to have the note removed from 
Eremaea to not confuse future searches for Great Shearwater. I definitely don't 
want to scare you off. Please continue to report your sightings, Andrew.


Philip, I strongly disagree with your small leaps. They happen all too often 
and are wrong. I have been member of a number of rare bird committees on 
various continents. I often noticed that submitters don't consider the unusual. 
E.g. to me a report of a Bridled Tern clearly ruling out a Sooty Tern, doesn't 
mean that the bird was a Bridled Tern unless you also rule out a 
Spectacled/Grey-backed Tern (even though it is not [yet] on the Australian 
list). Another story is that of an adult male Lark Bunting reported to us when 
I was part of the New Jersey Rare Birds Committee. Lark Bunting is the only 
black finch-like bird in North American field guides but still highly unlikely 
in New Jersey. The photos proved it to be one of the African widow finches - 
obviously an escapee. Therefore in order to prove the small leap you have to 
make a big leap.


Often, once you are on the wrong track, you may get lost. So I guess, if you 
misidentify a gannet for a shearwater and you still notice its huge size, why 
not think of a Great [sic!] Shearwater or another large shearwater species? 
Therefore, I totally understand this thought - even without wishful thinking 
involved. Funny things do happen: I know someone whose name begins with "N" and 
ends with "ikolas" (no, it wasn't David James!) who screamed "Streaked 
Shearwater". This bird turned out to be the most gigantic shearwater I've ever 
seen with a wing span of 3.5 metres! It turned out to be a Wandering Albatross! 
Sh.. happens.


And yes, most - if not all - shearwaters dive, but to my knowledge and 
experience not in the way Andrew described it.

Finally, yes (1) the mystery tern was a Common Tern moulting from first winter 
to first summer plumage (note the seasons refer to the northern hemisphere) and 
(2) the mystery little speckled bird was a juv Rufous Whistler. I just didn't 
want to be the smart arse again - but I guess I am ;-)

Cheers,

Nikolas

Hi Jeff,

Thanks for your comment. Sorry if you or others think so, I wasn't intending
"way overkill". I am curious at the general phenomenon (not just this case)
of people making big leaps of identification, rather than small leaps and
wondering why this sort of thing happens somewhat often. A very long time
ago (20 to 30 years) when I was seasick on a pelagic trip, I looked up at
something, probably not very clearly, and thought I had seen a distant
Wandering Albatross, because it was mainly white above, but that thought
only lasted a few minutes. No doubt it was an adult Gannet. So why did I
want it to be a Wandering Albatross, simply because I wanted it! But that is
a species you could reasonably expect to have encountered at that place and
date. 

It is interesting why would an identification go to that particular species
(Great Shearwater) which is unlikely just on status. I understand a new
birder to our shores learning the ropes thinking what a great bird. But
curious as to the thought process. Could it be because it has been mentioned
recently? As in my question is about the role of wishful thinking in bird
identification over the whole range of people and experiences. I don't see
this as rubbing it in. 

And yes you are right that Great Shearwater is not ONLY "on the other side
of the world" (but usually is).

Lastly the question remains: Do any shearwaters feed by diving behaviour as
described? 

Philip

This is way overkill Philip, 

it was an honest mistake by Andrew McKey a new birder to our shores learning
the ropes, who was brave enough to put up a report for scrutiny. 
Should have been picked up by the forum administrators before going to air,
but has now been corrected by a couple of observant forum readers as a
perfect description for a young Gannet. Reports of late demonstrate clearly
that Great Shearwater is not only "on the other side of the world" and this
probably resonated with Andrew.

So why rub it in, cheers Jeff.

Sure we can make mistakes on confusing difficult species but I am amused by
this one, not at the making a mistake. I can understand someone saying I
don't know what it is but why come up with an idea of Great Shearwater? I
don't find it in my Aussie field guides, so why would that be in the mix of
ideas? Indeed Peter Harrison's Seabirds book shows Great Shearwater on the
opposite side of the world. Looking at the pictures of Great Shearwater in
that book does not raise images to me of similarity to a gannet. Gannet do
occur in UK. I think Michael Palin said he didn't like a British bird book
because it had the Gannet in it. 

Lastly, now I am curious. Do any shearwaters feed by diving behaviour as
described? I have not seen it. 

Philip
