Largest-ever Red-headed Weaver Anaplectes rubriceps colony

p 203-206

La plus importante colonie du Tisserin écarlate Anaplectes rubriceps jamais enregistrée. Le Tisserin
écarlate Anaplectes rubriceps niche normalement de façon solitaire, parfois en petites colonies. La colonie
la plus importante enregistrée auparavant comprenait 100 nids. Nous avons trouvé une colonie qui
comptait 210 nids, dont plusieurs étaient occupés, ce qui en fait la colonie la plus importante documentée
à ce jour. Pendant une seule séance de baguage auprès de cette colonie, 73 Tisserins écarlates ont éte
capturés, y compris deux reprises de 2007. Les nids accessibles ne contenaient pas d’oeufs ; neuf nids
avaient deux jeunes chacun. Un nid contenait un jeune Coucou didric Chrysococcyx caprius.

Summary. Red-headed Weavers Anaplectes rubriceps normally nest solitarily, sometimes in small
groups. The largest colony previously recorded held 100 nests. We found a colony that contained 210
nests, several of which were active, making this the largest colony documented to date. During a single
ringing session at the colony, 73 free-flying Red-headed Weavers were caught including two recaptures
from 2007. No eggs were found in those nests which were accessible; nine nests had two chicks
each. One weaver nest contained a Didric Cuckoo Chrysococcyx caprius chick.
