Bob, Based on what you described below, I DO believe most of the Murres
we saw were molting adults with a handful of what appeared to smaller,
"juvenile-like" birds accompanying adults. We birders on the ship were
chatting and commenting among ourselves about the Murres' nesting
failures. I think we did not distinquish as well as we should have the
true recently-fledged Murre from the accompanying molting adult.
Translate my expression of "fair number" to a few real fledglings and
perhaps 100 adults in various plumages scattered in mixed groups with
gulls and auklets. Our ship passed quite close to a small group of Murres
that definitely fit the description of kid(s) with Dad(s), perhaps 5-8
juveniles at the most.

However, there did appear to be a larger number (150-200+) of Rhinocerous
auklets in basic-like plumage that appeared to be "immatures." There were
also Rhino auklets in breeding/alternate plumage with larger bills
swimming amongst them. The auklets were scattered in the waters near the
island in rafts of a few to several dozen birds each.

Thank you for the extra education about the Murre's natural history;
I'll be looking more carefully the next time to distinquish and
specifically count the this year's birds.
