The phenology of fruit trees and avian consumption of fruit were examined in Wytham wood, Oxford in 1979-1980. Ripe fruit was available to and fed upon by birds from late August until early May. Observations made on a daily transect indicated that most of the fruit was eaten by tits and thrushes, but the two families differed in the seasonal consumption and species of fruit taken. Tits took fruits of Elder, Bramble, White Bryony, Honeysuckle, Black Bryony, and Woody Nightshade at the beginning of the season only, while thrushes consumed fruits of Elder, Bramble, Hawthorn, Sloe, Rose, and Ivy mainly in the middle and end of the season. Members of these two families also visited different habitat types following the consumption of fruit, probably effecting different patterns of dispersal. There was no correlation between feeding preferences and the abundance or profitabilities (as defined by Pyke et al. 1977) of fruits with respect to total nitrogen, total proteins, total carbohydrates, total fats, or kilocalories. It is concluded that other factors such as palatability or content of other nutrients may be important in determining the feeding preferences of different species of frugivorous birds.
