This article describes flocking behaviour and dispersion of Helmeted Guineafowl, Numida meleagris, on and around maize fields during the crop-sowing period (November–December), reflects diet analyses and estimates seed loss. A field transect survey (80 km) was conducted through maize farms in the Heidelberg, Vaaldam area (Gauteng province) and the Balfour area (Mpumalanga province) in South Africa during 2013 to count Guineafowl. Maize, Zea mays, seed loss ascribed to Guineafowl was estimated to be <0.12% of the total harvest. This low impact is probably due to the low density of Guineafowl because of breeding territories required by pairs.
