History
Bird Island was conceived and constructed by Adolf Winter, a German who emigrated to
South West Africa
South West Africa ( af, Suidwes-Afrika; german: Südwestafrika; nl, Zuidwest-Afrika) was a territory under South African administration from 1915 to 1990, after which it became modern-day Namibia. It bordered Angola ( Portuguese colony before ...
(now known as Namibia) in 1912. Winter took a train from Swakopmund to nearby Walvis Bay and saw a natural offshore formation called Bird Rock, covered in guano from many birds. On the return trip, he noticed the guano had been washed away by the sea and saw a business opportunity.
Bird Island began as a wooden platform measuring four meters square, three meters above the sea. Winter finished this initial construction in March 1930. One year later he had enlarged the platform to 16 meters square, and by August 1931 had extended it to 1600 square meters. Guano was collected and sold annually, and expansion of the platform continued at a slower pace until 1937, when a large shipment of timber allowed building the platform out to its current size of 17,000 square meters.
Economics
The guano collected from Bird Island is considered high quality for its high nitrogen content relative to other guano collection facilities in the region. It is cleaned in Swakopmund to remove feathers and other debris, ground to a powder, and exported to Belgium for US$285 per ton.
[Plaque at the National Marine Aquarium of Namibia, Swakopmund] The platform yields approximately 650 tons of guano annually.
