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.

PHOWN records from Eritrea

PHOWN records in Asmara, Eritrea

In early June 2018 Pieter Cronje visited Asmara in Eritrea and found a large number of weaver nests. Most nests he found were Baglafecht Weaver nests, and a few were Village Weaver nests. Together with Ruppell's Weaver, these are the most common Ploceus weavers in Eritrea.

Although there were two PHOWN records from Eritrea previously, Pieter's sample has increased the number to over 100. This puts Eritrea in tenth place for number of PHOWN records per country (see country totals).

Interestingly, most of the Baglafecht Weaver nests were found in palm trees, a nesting site known for this species (although as a site used occasionally). The nests of this weaver are built underneath the palm fronds, often near the trunk but sometimes closer to the tip of the frond.

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).

Ringing at Fynbos Estate (Paardeberg), 25-27 May 2018

Some of the birds ringed at Fynbos Estate

The first ever ringing trip at Fynbos Estate, Paardeberg, was undertaken on 26-27 May 2018. Barry and Sue Schultz, Les Underhill and Dieter Oschadleus spent the weekend in the Black Eagle cottage to ring near the cottage area. There was a reed patch where weavers roosted and visited during the day, and there was a row of trees and bushes, both areas resulting in a steady flow of birds. The top species for ringing were Cape Weaver (n=62), Cape White-eye (51), and Cape Robin (14). We were surprised at the diversity of species caught: 24 species in total, including all 3 South African mousebirds, 4 weaver species, 2 shrike species and 2 sunbird species. The star species was the Cardinal Woodpecker, with 2 males being caught (surprisingly one was caught in the nets at the reeds!).

Les put a "moth trap" at night to photogrpah moths for LepiMap.
Cape Weavers in the palm tree at the farm house were already building new nests.
Thanks to Diana and Johan Simms for a wonderful weekend!

Bowwood (Paardeberg) repeat ringing, 21-22/04/2018

2018-04-23 (820)
pic
Ringing sites were around the farm house, surrounding vineyards, and woodland patches
The second ringing trip to on Bowwood Farm, Paardeberg, was undertaken on 22 April 2018, 3.5 weeks since the previous visit. The top species was Cape White-eye again (n=26), but no white-eye recaptures. The table below compares the species totals from the 2 trips.
Nearly the same total number of birds was caught on both trips with 6 species caught both times. The April trip yielded more species, however, since nets were scattered over a wider area. Interesting catches included a Cape Batis and some Swee Waxbills. Four birds were recaptured: 1 Olive Thrush, 2 Karoo Prinias (clearly a pair, being caught at the same time on each trip), and 1 Southern Masked Weaver.

Thanks to Julian and Bridget Johnsen for hosting us!
