Nov. 24 somewhere in the impenetrable ocean.
Reading through a batch of sooty tern I came
upon something interesting. Yesterday at 07°18S 173°18'W,
about (in weymouth miles) 180 miles from the nearest breeding
island (Hull), I collected 5 ad. sooty terns. Aside from
their all being BT, which may or may not mean something,
they possibly show a good story with possibly, a interesting
ending (to me anyway). Each bird when arranged in order
of progressive molt of the primaries and secondaries are only
one primary ahead of the preceding bird. When placed
in order of progressive tail molt 4 out of the five correlates
with the primaries. I am going to have to stop here and explain
my theories (or better yet ideas) on the etiology of sooty tern
Primolt. For convenience sake I will break it
down to Betsy's P-1-3 replaced, 4-6, replaced, 7-9 replaced
and their 10 replaced. So at sea bird I cannot
correlate molt with anything but say were over islands.
New=old-new would be on offshore high forefood paths). 1-3replaced
would be on mid to wey large chick), 7-6 would be only
imm and shortly beyond after they leave the island (Prepatation & patch).
and T# 7-10 somewhere out of sea many days
date (perhaps on this watering ground. I don't know
whether they normally make another round at
molt or not before they come back to the island
to breed or not but I suspect not. But anyway
by the time they start nesting again P#1 is about
1/2 grown and R#6 is about 1/2 grown. When they
settle down to nest BP is almost all unfeathered.
R#6 band new and unbroken and Pal new. Well
to get back to my 5 sooty coll at Sea. Bird #1
loss R all new but #6 1/2 and P1-7new 8-10old first step.

I guess I'd better present this in a better way.

I know I read for more than five birds to show anything but what I am getting at is do birds that
decision for some outside stimulus do not go back
to the island to breed every year (weak, sick,
lack of food supply around breeding island, bad weather for breeding etc)
go through a partial breeding cycle at sea. Like, for
example gorade gosip and regura and BP partially unfeathered
and then repeateth. Just try I shot a almost ad subad
and it's ovary was up but it's oviduct had never
been used. ? ???
