Latest PHOWN species - Crested Malimbe

2018-10-14 (827)
The newest PHOWN species to be added is a record of the Crested Malimbe. Maans Booysen photographed a Crested Malimbe building its nest in Kakum Forest in Ghana earlier this year. The subspecies in West Africa (nigrifrons) has a smaller crest than the nominate.

PHOWN now has records of 94 of the 117 weaver species (80%). The weavers without PHOWN records are listed below - for some the nest has not even been described yet, while for some nests should be easy to find and photograph. (click on the species to read more about it).

PHOWN, PHOtos of Weaver Nests, is a Virtual Museum, citizen science project of the Animal Demography Unit, to collect and monitor breeding distributions and colony sizes of weaver birds globally. To take part, register and upload records at Virtual Museum (read the "How to" pdf for help).

Weavers with blue eggs

2018-10-11 (826)
There are 18 species of weavers that usually only lay pure blue eggs. Blue or blue-green eggs are very widespread in birds generally, resulting from the predominant deposition of the pigment biliverdin (Walters 2006a). Many other weavers lay eggs with a variety of colours, so some individual females may lay pure blue eggs, while other individuals of the same species lay eggs of various colours and markings.

The list below includes two quelea, three fodies, two bishops, and 11 other weavers.

See also white eggs.

Weavers with eggs that are plain blue or sometimes plain white:

Yellow-mantled Weaver Ploceus tricolor
Olive-headed Weaver Ploceus olivaceiceps

Nesting in Asian weavers

2018-09-28 (825)
The 5 Asian weavers weave their nests as other true weavers do, and the male does most of the building, and females line the nests. Asian weavers may use mud and flowers in their nests, and various theories have been proposed to explain this - the most likely reason is that the male uses mud to attach flowers to the nest. Some differences in the nesting of the 5 species are listed in the table below.

Factor Asian Golden W Baya W Bengal W Finn's W Streaked W
Pair bond Monogamous Polygnous Polygnous Polygnous Monogamous
Colonial Small Colonial Single, small Colonial Colonial

Red-billed Quelea flocks

2018-08-21 (824)
On 20 Nov 2017 I was on farm Swebe-Swebe in Limpopo Province watching vast flocks of quelea flying into their roost in extensive reedbeds along a river. As I was videoing and watching in amazement, I pondered how many quelea there could be in this roost, coming from the surrounding savanna. Compact flocks seemed to contain tens to hundreds of birds each in a never-ending stream. A screen shot from the video allowed me to estimate a conservative 300 birds per second passing, so in one hour that comes to about a million quelea. No wonder this is considered the most numerous bird on the planet!

Red-billed Quelea flocks arriving at roost at dusk. The first clip shows a raptor flying above the flock but not able to single out a bird. The second clip shows birds veering out from the stream to settle in the reeds and trees along the river, while the rest continue to settle some distance away.

Top SAFRING ringing sites over 70 years

2018-08-15 (823)
This quick summary shows the top degree-minute grids for each major region (South African province, main African countries with data) in the SAFRING database. No checking has been done, so there are likely to be some errors. Also, some ringing localities may cover two grids, but this query is strictly totals by grid (rather than by locality). These numbers depend very much on where ringers have ringed a lot over the decades.

Table 1 shows the grid with the most number of species ringed in that grid (per region).

Barberspan is the top site for number of species and number of birds ringed. This is due to high ringing effort in the 1960s in ringing waterbirds, combined with the effort of ringing in recent years using mistnets as well as walk-in traps for waders and waterbirds. Several regions have the same site as top grid for species and totals ringed.

SAFRING celebrates its 70th anniversary this month, the first birds to be ringed were some Cape Vultures ringed in August 1948. Read a short history of bird ringing in southern Africa at the Biodiversity and Development Institute web site.
