PHOWN priority: Village Weaver Ploceus cucullatus

Are Village Weaver colony sizes larger or smaller closer to the equator?

The Village Weaver has one of the widest distributions of weavers in Africa, although its range is limited in southern Africa. There are several subspecies, showing some geographic variation. This species is ideal to study colony variation on a continental scale, especially as this species is fairly common and nests are fairly easy to find within its range.

You can help answer the above question by submitting PHOWN records (with nest counts) for this species and the results will be automatically updated below (as soon as your record has been accepted).

Table 1

This table shows up-to-date variation in colony size in Village Weavers for PHOWN records at different latitudes, at 10 degree intervals.
Note: Latitude -30 is [40S to 30S] (range 33S to 30S); -20 is [30S to 20S]; -0 is [10S to 0S]; 0 is [0S to 10N]; etc.

Latitude Min Mean Max n
-30 1 52.6 205 55
-20 1 30.0 300 849
-10 1 60.2 250 12
-0 1 59.8 400 31
0 1 95.2 500 25
10 5 149.0 450 7

Table 2

This table shows up-to-date variation in colony size in Village Weavers for PHOWN records at two latitude intervals.

Mean colony size from 33S to 10S = 31.7
Mean colony size from 10S to 15N = 83.8

Currently the average colony size seems to increase with latitude.

Counting nests in large weaver colonies.

Counting the nests of Village Weaver (and some other weavers) requires a little effort - their colonies are often large with up to a few hundred nests.
