Sequentially select and delete the four graph legends. In 1910, there were probably approximately 1.4 million adult birds in one population alone at Dassen Island, which had been reduced to about 145,000 birds by the mid-1950s. Round Herrings.-Other Marine Animals include Squid and Crustaceans. African Penguin populations, living on the southern African coast, have declined from 2 million pairs in the mid-19th century to only 25,000 pairs today, says Phil Hockey, director of South Africa’s Centre of Excellence in 'Birds as Keys to Biodiversity Conservation', at the Percy FitzPatrick Institute of African Ornithology, University of Cape Town. The only penguin occurring regularly in southern Africa, African penguins (like Humboldt penguins) differ from Magellanic penguins in that they lack a second dark breast band (although some African penguins do have an additional breast band). They make plenty of vocal sounds like other species of penguins. Type to create the four text labels. Your friend's email. These vocalizations allow them to identify their mate, to communicate with offspring, and to warn of any dangers. order sphenisciformes family sphenisciadae genus spheniscus speices demersus symbiosis

African Penguins Spheniscus demersus recolonized Robben Island in 1983 when about nine pairs bred at the island. At the same time, the chinstrap and gentoo penguins that prefer ice-free habitats have experienced population booms in the southern part of the Antarctic Peninsula as sea ice has declined. Minimum Origin Version Required: Origin 2015 SR0 . Despite a large portion of the population living within protected areas, poaching poses a serious threat to the species. The following graph shows that before the galapagos penguins were considered to be endangered, their population was in the range of about 2000-3000 individuals. Works Cited.

To add to the problem, experts suggest that within the next 20 to 30 years habitat loss will also pose a greater threat due to use of land for agriculture, timber extraction and mining.
