COMMENTS ON TAXONOMY -
Some sources place it under genus Calonectris; Scopoli
(1769) classified it Procellaria diomedea; Cory (1881) called it
Puffinus borealis; Bent (1922) classified it as Calonectris kuhlii
borealis; today there are three subspecies recognised, two of which
frequent Atlantic coast waters, most commonly C.d. borealis, less
commonly C.d. diomedea *3950,2484,606*; AKA Mediteranean shearwater,
North Atlantic shearwater, Cape Verde shearwater *1500*

LIFE HISTORY
PHYSICAL DESCRIPTION: yellow bill, light underside *624*;
REPRODUCTION: breeding season = late May to late July *3950,2484,4029*;
daily periodicity = nocturnal feeder during breeding season *3950*;
incubation = 52-55 days, average 53.8 days *3950,4029*; reproductive
periods/Year = 1 brood *3950*; breeding behavior = detailed by sources
*3950,2484,606*; clutch size = 1 *3950,2484,606*; BEHAVIOR: seasonal
periodicity = occurs only from August to November off the Atlantic coast
*606,1500*; migration = makes trans-Atlantic flight during late summer
and fall from breeding grounds in eastern Atlantic to feed along western
Atlantic of North America *606,3950,2484,624,1500*; foraging
strategy/sites = marine open water, usually feeds along surface, known
to scavenge behind fishing vessels *2484,3950*; nest site = colonial
nester on uninhabited islands, among caves, less steep portions of
cliffs, boulder fields, or bare ground *3950,2484,4028,606*; parental
care of young = brood constantly for first few days then leave young to
feed at night *3950,4029*; ORIGIN: native *624,700*; AQUATIC/TERRESTRIAL
ASSOCIATIONS: loose association with greater and sooty shearwaters
(Puffinus gravis and P. griseus) *2484*
