Ah Michael,
I wasn't even *considering* implying any prevarication :-). It seems
that having a number of booby sightings early in a warm-water event
should make sense.
I was curious, though, if folks might speculate on why boobies might not
continue to show up throughout an extended warm-water event? I can guess
that perhaps those that did 'pioneer' up here might not have found much
in the way of food and good southern climes to induce them to stay or return.
Continued ENSO might have diminished the production of seabirds in their
southern colonies such that the fledging juveniles that *might* wander
north are reduced in numbers - making a rare occurrence even more unlikely?
I wonder whether the occurrence of *other* southern-type seabirds, which
show up more regularly, might be correlated with the strength or duration
of warm-water ocean conditions? For example, might frigatebirds occur
more frequently at the start of an extended El Nin~o event than later?
We might have this sort of information for the 1991-94 period buried in
field notes, but it would take someone to research and compile the data.
Just speculatin'.
