The importance of pest birds and their identities are still poorly understood by Congolese farmers, yet they cause significant damage to crops. The main objective of this study was to assess the damage caused by predatory birds on the sowing, germination, and vigor at emergence of three staple crops: maize (Zea mays), peanuts (Arachis hypogaea), and rice (Oryza sativa), under the ecological conditions of Kinshasa/Mont-Amba. Our results showed significant differences in damage during sowing, with a notable average of 40% more damage to maize compared to rice and peanuts, and an average of 48% for rice, leading to a general average of 106% damage across the three crops at emergence. For developing seedlings, a remarkable average of 44% damage was observed in maize. A preliminary identification of predatory birds was also conducted. The bird species recorded during this study include: Quelea quelea (red-billed weaver), Ploceus cucullatus (masked weaver), Passer luteus (yellow sparrow), Quelea erythrops (red-headed weaver), Ploceus spp., Lonchura cucullata, and the crow. The experimental work revealed considerable damage caused by birds to maize, peanut, and rice crops in Kinshasa. Finally, the promotion of appropriate anti-bird control methods would be an effective means of rational management of pest bird populations for these crops, which would consequently help reduce their damage.
Author Keywords: bird pests, predators, emergence rate, damaged seedlings and pest control.

Abstract: (french)
L’importance des oiseaux ravageurs et leurs identités sont encore peu connues par les agriculteurs congolais, pourtant ils causent de dégâts importants sur les cultures. La présente étude avait pour objectif principal d’évaluer les dégâts causés par les oiseaux dépredateurs sur le semis, la germination et la vigueur à la levée de trois cultures vivrières dont le maïs (Zea mays), l’arachide (Arachis hypogaea) et le riz (Oryza sativa), dans les conditions écologiques de Kinshasa/Mont-Amba. Nos résultats ont montré des différences significatives de dégâts sur le semis avec une moyenne remarquable de 40% de plus sur le maïs par rapport aux riz et arachide, et avec une moyenne de 48% sur le riz et 106% comme moyenne générale pour les 3 cultures à la levée. Sur les plantules en développement, il a été observé une moyenne remarquable de 44% sur le maïs. Une identification sommaire des oiseaux déprédateurs a aussi été faite. Et les espèces d’oiseaux qui ont été recensées au cours cet essai sont: Quelea quelea (travailleur à bec rouge), Ploceus cucullatus (gendarme), Passer luteus (moineau doré), Quelea erythrops (travailleur à tête rouge), Ploceus spp, Lonchura cucullata et le corbeau. Le travail expérimental a révélé l’existence dégâts considérables causés par les oiseaux sur les cultures de maïs, d’arachide et de riz à Kinshasa. Enfin, la vulgarisation des méthodes de lutte anti-aviaire appropriées serait un moyen efficace pour une gestion rationnelle des populations des oiseaux ravageurs de ces cultures, et permettrait de réduire, par ricochet, leurs dégâts.
Author Keywords: oiseaux ravageurs, déprédateurs, taux de levée, plantules endommagées et lutte anti-aviaire.
