dc.descriptionThe feeding ecology of Turdus pelios was studied from field observations and gizzard contents. Quantitative data on feeding were obtained from repeated standard “fixed route” walks and observational points at seven sites from January to December 1998 on 5065ha at the Obafemi Awolowo University campus, Ile-Ife (7º20’ N, 4º33’ E). Walks (each lasting about two hours) were started at various times of the day between 7.00 and 16.45 h. A total of 100 walks were made and binoculars were used to observe all feeding activities during 10 minutes at each site. Each feeding record included food type, method of feeding and reaction with con-specifics at feeding sites. Gizzards from mist-netted specimens were also studied. These birds fed most commonly twice a day between 06.00-9.30hr in the morning and between 17.00-18.30hr in the evening. Field observations showed that about 62% of the diet consisted of plant matter. The prey items were earthworms and terrestrial arthropods, of which orthopterans alone constituted 45% of the total. The prey size consumed by both sexes overlapped extensively: differences in prey size were significant only for spidersen-US
dc.descriptionSe examina la ecología alimenticia del ave Turdus pelios en Nigeria, África. Se observó que se alimenta frecuentemente dos veces al día entre 6:00 - 9:30 am y entre las 17:00 - 18:30 pm. Observaciones de campo mostraron que alrededor del 62% de la dieta consite en material vegetal. Las presas fueron lombices y artropodos terrestres, de los cuales los ortópteros constituyen el 45% del total. El tamaño de las presas consumidas por ambos sexos se traslapa ampliamente, y las diferencias fueron significativas solamente respecto al tamaño de las arañas (los machos consumieron más).es-ES
