The Alte Kalköfen Bird Observatory, probably the fifth in Africa, was formally opened on 8 February 2025 after a two-year proof-of-concept study. Unlike most bird observatories, the research opportunities it presents are primarily focused on resident and nomadic species, rather than on migrants. The Alte Kalköfen Bird Observatory is located in semi-desert, and many of the bird species that occur in this area are therefore nomadic. Almost all these bird species are poorly researched; thus one of the key objectives of the Alte Kalköfen Bird Observatory is to study nomadism in these species. We aim to gain an understanding of their biology and ecology, this is a missing component which is needed to maintain and develop biodiverse natural habitats for all animals in the district. 

Introduction 

The first birds were ringed at the Alte Kalköfen Lodge on 15 January 2023; during the following 3.5 months, 3,440 birds of 56 species were ringed.  A proof-of-concept study was done during the next two years; one discovery in this period was of five species outside their known ranges in southern Namibia.

Given the large number and variety of birds, it was decided to launch the Alte Kalköfen Bird Observatory officially. This was done on 8 February 2025. For more detailed information, please have a look at our Brochure under the "Brochure" tab on this page.
