These are the most widespread of penguins, and Simpson notes that wherever two species of this genus occur together, one is bound to be E. crestatus. 10 lbs Crests similar to those of Macaronis, but the chin and face are white. Simpson notes also that the cheek is often palely striped. By day they remain in their shelters. Oddly, however, in some parts of Australia large numbers do go into the sea and return to land together, a phenomenon not recorded elsewhere.
Details are as for E. minor .
The best book I have come across so far on penguins is Penguins, Past and Present, Here and There , by Dr George Gay Simpson, Yale University Press 1976. Although only about 150 pages long, it is both informative and witty. It may now be out of print.
