ERECT-CRESTED PENGUINS (Eudyptes sclateri)

SIZE:

  • Up to 25 in. (64 cm)
  • 6-8 lb (2.5-3.5 kg)

THREAT LEVEL:

Endangered

DISTRIBUTION:

Australia, New Zealand, Bounty Island, Campbell Island, and Auckland Island

HABITAT:

Erect-crested penguins tend to breed on rocky slopes along the shore. While a limited few pairs will build nests,  most lay their eggs on the rocks. After a long courtship period two eggs are laid but the first, much smaller, A-egg is invariably lost, in most cases on the same day or before the B-egg has been laid.

MARKINGS:

When dry, an erect tuft of yellow feathers is the easiest marking. When in the water, the yellow feathers lay flat and make identification more difficult. Often confused with Snares and Fiordland penguins, erect-crested penguins have a distinct gular pouch (throat skin), a more parallel bill, and the yellow supercilium attaches higher on the bill than in Snares and Fiordland Penguins.

NEST TYPE:

colonies in the open; nest on rocks with little to no nesting material to line nests

PREY:

Never conclusively studied, but believed to be mostly squid and fishes

PREDATORS:

Never conclusively studied, but believed to be mostly New Zealand sea lions, New Zealand fur seals, Australian sea lions

POPULATION ESTIMATE:

  • 55,000 breeding pairs
