One of the most fascinating species in Bitterwasser is the Sociable Weaver. These birds are true architects: they build massive communal nests that are often used for decades and continually expanded. These nests are typically found in tall acacia trees and can house hundreds of birds. Their unique structures provide protection from predators and extreme temperatures, making them one of a kind in the bird world. Each communal nest is made up of numerous small, individual nesting chambers that form a large, hanging structure.
In contrast to the Sociable Weaver, the White-Browed Sparrow-Weaver is more solitary and builds its intricate nest alone. Each nest is carefully constructed, with a small entrance leading into a spherical chamber that protects the brood from predators. White-Browed Sparrow-Weavers are not only known for their nests but also for their song, which fills Bitterwasser with lovely melodies.
Bitterwasser is a wonderful place to enjoy nature, not only because of its weaver birds but also because of the rich variety of bird species. Over 100 bird species can be observed here—from birds of prey soaring over the desert landscape to smaller songbirds nestled in the bushes and trees. The early morning hours are especially ideal for birdwatching, as many birds are most active then.
In early September, the containers holding the gliders for the 2026/27 season were loaded in Waghäusel. Transported by trailer, truck, and cargo ship, the gliders are now on their long journey to Namibia, to the Bitterwasser Flying Lodge.
The Bitterwasser Flying Lodge was the main sponsor of the Junior World Gliding Championships, where from August 2 to 17, 2026, around 80 pilots from 22 nations competed for the titles in the Standard and Club classes. The grand prize for the JWGC winners was a one-week stay at the lodge, including travel and an airplane.
