Influence of mistletoe on woodland bird assemblages

These data relate to patch-scale woodland bird surveys, before and after data both relating to four combined standardized searches per patch (carried out seasonally). Data relate to richness (presence only) and incidence (number or samples in which species were recorded as present as a function of the total number of samples). Subsets of these two variables are presented relating to all species, woodland-dependent species, woodland-dependent residents, insectivores and ground-foraging insectivores.
