Diet of Eared Doves (Zenaida auriculata, Aves, Columbidae) in a sugar-cane colony in South-eastern Brazil

Abstract: Farmers in the Paranapanema Valley (São Paulo, Brazil) have reported problems with flocks of Eared Doves (Zenaida auriculata) eating sprouting soybeans. In this region these birds breed colonially in sugar-cane, and eat four crop seeds, using 70% of the dry weight, in the following order of importance: maize, wheat, rice, and soybeans. Three weeds (Euphorbia heterophylla, Brachiaria plantaginea, and Commelina benghalensis) were important. This information suggests that the doves adapted particularly well to th… Show more

“…In general, species with a larger body mass require more food to fulfill their high energy demands, and a greater time spent at a foraging site can provide these individuals with the opportunity to obtain more resources. It has been recorded that an increase in the the food item preferred by species in this study; this was also the case in studies of C. talpacoti in the Venezuela savanna (Pérez & Bulla 2000) and Central Brazil (Cintra et al 1990), and of Z. auriculata in southeastern Brazil (Ranvaud et al 2001), in southern Brazil (Cândido-Junior et al 2008), in northwest Venezuela (Chacín & Calchi 2007) and in Argentina (Murton et al 1974). Moreover, Z. auriculata can be considered to be legitimate seed dispersers (Bucher & Bocco 2009).…”

“…Eared Doves tended to concentrate in areas with higher frequency of maize and soybean plantations. Maize was the most abundant food item (46% of dry weight) of Eared Doves in a study in the same region (Ranvaud et al, 2001). Sugar cane plantations, known as potential sites for reproductive colonies , also favored higher abundances in summer.…”

“…They form a superspecies with the Mourning Dove, Zenaida macroura, distributed throughout the Neartics (Goodwin, 1983;Baptista et al, 1997). Eared Doves benefited from changes in the landscape resulting from the replacement of rangelands and forested areas by agriculture, which occurred mainly after 1950 in several regions of South America (Murton et al, 1974;Ranvaud et al, 2001). Information of large population densities and damage to crops at different locations has been reported since 1970 (Londoño et al, 1972;Bucher, 1974;Murton et al, 1974;Ranvaud et al, 2001).…”

“…A substituição das florestas por áreas de pastagem e de cultivo de grãos favorece espécies que habitam naturalmente áreas abertas, semi-abertas e bordas de florestas (STOTZ et al, 1996). Nas regiões sul e sudeste do Brasil, Z. auriculata ocorre em vários hábitats, com exceção dos florestais, inclusive em cidades, e aparentemente explora diferentes tipos de recursos alimentares tais como restos alimentares produzidos pelo homem, e alguns tipos de sementes de interesse econômico (por exemplo: soja, trigo e milho), embora sua preferência seja por sementes de plantas silvestres (RANVAUD et al, 2001). Em vários países da América do Sul, como Colômbia, Argentina e Brasil, a espécie tem sido considerada localmente uma praga para a agricultura (MURTON et al, 1974).…”
