Weaver news
In March 2010 there were 51 nests in three colonies - two colonies may be viewed in PHOWN and the third colony was in the campsite and had 5 nests. This suggests an increase in the population but doesn't show how the population changed over time. SAFRINGs ringing records were extracted (red line in Fig. at right) but ringing at the office and camp area was too sporadic to draw firm conclusions. In recent years retraps (green line in Fig.) have been submitted more frequently and this could allow survival to be estimated. There is an atlasing and ringing workshop at Barberspan from 9-16 March 2011, and there will be ringing and PHOWNing to compare the current population with last year. |
