About the Cook's Petrel
Cook's petrel (Pterodroma cookii) or tītī (Māori), blue-footed petrel, is a Procellariiform seabird endemic to New Zealand. It is a member of the gadfly petrels and part of the subgenus Cookilaria Bonaparte, 1856, which includes the very similar Stejneger's petrel.
One of the smallest petrels, Cook's petrel is typically 25–30 cm (9.8–11.8 in) in length with a 65–66 cm (26–26 in) wingspan and a weight of around 200 g (7.1 oz). Its colouration is typical of gadfly petrels: pale grey upperparts with a dark grey "M" on the wings and white underparts.
The bill is long and black with tubular nostrils on both sides. As in all members of the order Procellariiformes, this nostril configuration enables an exceptionally acute sense of smell, which the birds use to locate food and nest sites in the dark.
Cook's petrel feeds mostly on fish and squid, with some crustaceans taken. The species is highly pelagic except when nesting. Cook's petrel breeds only in New Zealand on three small islands: Little Barrier Island, Great Barrier Island, and Codfish Island. The breeding season is the southern summer, from October to May. It nests in burrows and rock crevices... Wikipedia →
