Raptors are known to breed on top of weavers nests but are they willing to follow the weavers onto man-made structures?

Paper: Oschadleus HD. 2019. Raptors breeding on weaver nests in trees and on man-made structures. Ostrich 90(1):85-88.

Abstract. Several raptor species nest on top of large weaver nests. These weaver nests are usually sited in trees, but 11.7% of Red-billed Buffalo-Weaver Bubalornis niger and 25.7% of Sociable Weaver Philetairus socius nests occur on man-made structures. In an extensive literature search, a total of 16 raptor species were recorded as nesting on top of weaver nests. At least 10 raptor species used weaver nests built in trees. Seven raptor species used weaver nests on man-made sites and four raptor species only used weaver nests built on man-made sites. No owls have been recorded as using weaver nests on man-made sites. There are historical records of raptors nesting on top of weaver nests in trees, while nesting on top of weaver nests sited on man-made structures appears to be a more recent adaptation. Costs and benefits of nesting on man-made sites are briefly listed. Nesting on man-made sites may increase (by both weavers and raptors) and raptor researchers are encouraged to document cases of raptors nesting on weaver nests where these are placed in trees or artificial sites, so that there is a record of changes in frequency of nest site usage by raptors.

Ringing expedition to Fynbos Estate, 18-28 February 2019

Ten days were spent at Fynbos Estate to ring birds, as a BDI expedition. The ringers were Dieter Oschadleus and Manuel Puertas (Spain), assisted by trainees Samantha McCarren (Germany), Emmanuel Adekola (Nigeria), and Joel Radue. Les Underhill and Pete Laver helped with logistics and promotion (helped remotely by Megan Loftie-Eaton). On two mornings the Tygerberg ringers (Margaret McCall and Lee Silks with their tranees) kindly let us join their ringing at two farms, Goedeontmoeting and Rocklands.

A total of 375 birds of 27 species were caught at Fynbos Estate, including 31 recaptures of birds caught on earlier days, oe in May 2018. The most ringed species was the Cape Weaver, and the most recaptures were of the Cape Robin-chat. Migrants caught included Barn Swallow and African Paradise Flycatcher. Other exciting captures included Lesser Honeyguide, and its host - Acacia Pied Barbet.

At the two farms, and additional ten species were caught by our group. At Goedeontmoeting a female Southern Masked Weaver (ring BH60921) was recaptured 8.6 years after it was ringed.

Moult analysis. We ringed many Cape Weavers at Fynbos Estate. Moult score was calculated (some birds were not scored due to high catch rate), with an average score of 48.1 (n=49). This was compared to Cape Weavers caught in Cape Town wetlands in February over years 2015-2018, giving an average moult score of 41.9 (n=16).

Thus rural weavers (at Fynbos) seem to have advanced moult scores due to starting moult earlier, and also completing breeding earlier, than urban weavers in Cape Town. Although small sample sizes, this illustrates the potential for ringing studies. A variety of projects are planned for on-going expeditions to Fynbos Estate.

Village Weaver northern race

2019-03-07 (833)
Christa Moller emailed photographs of a Village Weaver male at Zwartkloof N.R. Bela Bela, Limpopo Province, South Africa. The male had a black head, resembling the subspecies nigriceps. Christa first noticed the male at the bird feeder on 03/03/2019 and again on 04/03/2019. Christa did not observe this male in the fever tree where the normal-plumaged Village Weavers are nesting.

Third Clarke's Weaver breeding colony

2019-01-27 (832)
In December 2018 Fleur Ng'weno and a team of birdwatchers found the third colony of Clarke's Weaver.

37 December 2018over 100 nests in wetland sedges PHOWN record

All 3 records of breeding were of nests in sedges in wetlands in the Dakatcha woodlands. The breeding seasonality varies widely, probably depending on local rainfall, as the sedges need to be in standing water. The colonies are north of the Arabuko-Sokoke Forest (dark green patch in google satellite photo below), the forest being the traditional locality for birders wanting to tick this species.
