Subject: [SEABIRD:735] double-brooding seabirds

Dear Seabird-list colleagues:

I'm looking for information about double-brooding in seabirds. I define
"double-brooding" as a pair raising (or attempting to raise) more than one
brood per annual nesting season, rather than just laying a replacement
clutch after a nesting failure.

I've documented that about 40% of pairs in a Hawaiian population of Black
Noddies successfully double-brood. In the literature, I've seen reports
of double-brooding in some Silver Gull and Common Tern populations, and
I've heard that some Cassin's Auklets also do so.

I would appreciate hearing about other cases of known or suspected
double-brooding in a seabird species.

Thanks in advance for your help,
