When we returned to our Mossel Bay home recently we were once again thrilled to find the Cape Weavers (Ploceus capensis/ Kaapse wewer) working diligently at building nests right outside our upper floor living area. It was a repeat of the scene of a year ago, which I featured in a post at the time (https://wordpress.com/post/mostlybirding.com/10946)
They are a source of entertainment from dawn to dusk and leave me feeling quite exhausted just watching their frenetic activity as they build one nest after another, hoping to impress the female weaver who “pops in” for an inspection at fairly regular intervals.
We have had up to four male weavers nest-building at a time and currently there are at least two vying for the attention of the female, whose arrival is greeted by a display by the anxious males, who hang below their best nest and display.
The display is nicely described by Roberts VII Multimedia Birds of Southern Africa as follows :
Once nest initiated, male displays at nest by ruffling feathers, shivering partly spread wings, swivelling body and singing. If female enters territory, male displays either hanging below nest or perched alongside; may also pluck leaves from near nest. If female enters nest, male responds with high-intensity wheezing song, either while hanging below nest or during circular display flight. Female apparently tests nest strength by pulling at material inside nest, then, once male leaves nest entrance, sits in nest chamber looking out of entrance; chases off male if he approaches at this stage
The images I took of one of the males show some of the above behaviour
The male will even get upside down in order to impress the female …
Great fun to watch!
