An African Penguin swims in a pool at the SANCCOB sea bird rescue centre near Cape Town

Mashudu Mashau says it takes about two minutes to catch a penguin, a task he does weekly to investigate sightings of injured or sickly seabirds.

"We don't rush... we go down, sometimes we crawl, so that we don't look threatening, and when we're close, we aim for the head, hold it and secure the penguin," the 41-year-old ranger told AFP.
