On the coasts of South Africa only one species is met with. This is the Blackfooted or Jackass Penguin (Spheniscus demersus) which makes up in numbers for the lack of variety. It is found everywhere along the coasts from the southern part of Angola on the west as far as Port Elizabeth on the south, and can be seen at any time swimming about in the sea quite unconcerned, even in the harbour at Cape Town. These Penguins never voluntarily come ashore on the mainland but resort to certain small islands all along the coast for breeding purposes. Here they are to be seen in enormous numbers at certain times of the year and it is the purpose of this article to describe a visit to one of these islands made in order to observe these and other sea birds.
