Six million records in the SABAP2 database 

Six Million SABAP2 records

Six million records in the SABAP2 database. Team SABAP2, you have got from five million to six million in two days less than a year. The previous millions have all taken about 13 months (apart from the first, which took two years!).

We are steadily building not only the start-of-the-21st-century distribution maps, but we are also getting enough data on an annual basis to start thinking about mapping changes in bird distribution continuously. No one, nowhere, has come close to achieving this!

Well done, Team SABAP2. Seven million, here we come.

SABAP2 at 70% in South Africa, Lesotho and Swaziland 

SABAP2 at 70%

70% of the 17633 pentads in the original SABAP2 area of South Africa, Lesotho and Swaziland have been visited at least once. When we started the project on 1 July 2007 this level of coverage seemed an unimaginable pipedream. This is the day for a resounding celebration for the Citizen Scientists who have participated in the project. Well done, Team SABAP2. You are building the maps of current distribution for all our bird species. You are participating in the most important bird conservation project in the region. Without these maps, and the ability to compare them with the maps produced by the first bird atlas project, bird conservation would be based on guesswork.

Awesome new Virtual Museum feature: how to find the gaps in coverage 

VM Gap Analysis

This news item explains how to find the gaps in coverage in ADU Virtual Museum projects. On the Virtual Museum website, first choose (from the left hand side menu) the project you are interested in finding the gaps for. Then, from this menu, choose "Maps" and click on the tab "Gap Analysis" and then on "Request summary." A map like the one on the left appears. The grid generates the Quarter Degree Grid Cells. Those with data are coloured. Those without data are blank. Click on the grid cell you are interested in. A Google map like the one on the right appears. This grid cell is 2824DA and covers part of Kimberley, and a section of the Vaal River. It is the basic road map that appears first; I clicked "Satellite" at the top right corner to get this view.

If a grid cell has records, then a species list for the Quarter Degree Grid Cell appears under the map.

This is the Gap Analysis for LacewingMAP. It is little short of astonishing that this new section of the Virtual Museum already has records for 47 Quarter Degree Grid Cells, 2.3% of the region.

This is Version 1 of the ADU Virtual Museum Gap Analysis. It will be extended to cover Africa, and be extended to be able to find the gaps for specific time periods, for example, gaps since 2000.

FLUTTERBY FRIDAY is here!  

TGIFF - Thank Goodness it's FLUTTERBY FRIDAY! This stunning butterfly is a Little Pansy (Junonia sophia) -- the Little Pansy is a butterfly in the Nymphalidae family. There are two subspecies of this beautiful butterfly, namely: -- Junonia sophia sophia (Senegal, Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Burkina Faso, Ghana, Togo, Nigeria, Cameroon) -- Junonia sophia infracta Butler, 1888 (Angola, Democratic Republic of Congo, eastern Uganda, Rwanda, Burundi, western and central Kenya, Ethiopia, Tanzania, Malawi, northern Zambia)

The Little Pansy prefers forest and savanna habitat. The larvae feed on Paulowilhelmia sclerochiton, Hypoestes verticillaris, Brillantaisa lamium, Sclerochiton paulowilhelmina, Asystasia, Barleria, Justicia, and Ruellia species.

Weaver nests with long entrance tubes 
phown 5189 phown 1028 phown 5320 phown 11499 phown 5338 phown 8416

Several weaver species regularly build nests with long entrance tubes, although some individual nests have shorter tubes:
Baya Weaver phown 7442
Black-throated Weaver
Nelicourvi Weaver
Dark-backed Weaver
Black-necked Weaver
Spectacled Weaver
Gola Malimbe
Cassin's Malimbe
Red-bellied Malimbe
Ibadan Malimbe
Rachel's Malimbe
Red-vented Malimbe
Red-headed Weaver

Often long tubed nests are built by solitary, monogamous weavers. This group of weavers usually consists of a pair and they build the nest together. In some malimbes, a group of birds help build a nest. The long tube probably reduces predation but does not stop some predators. In the polygnous weavers it is usually the male that builds (although the female lines an accepted nest) and males want to build many nests in a breeding season, rather than spending energy on building nests with long tubes.

Thanks to the observers who submitted these records! Please record and submit your record of weaver nests to PHOWN (PHOtos of Weaver Nests) via the Virtual Museum upload site.
