Seasonality and dietary diversity in flower and fruit consumption: long-term dataset from a New Zealand Wildlife Reserve (online supplementary material)

Dataset containing monthly records of bird-flower and bird-fruit visitation collected by Dr KC Burns in Zealandia wildlife reserve in Wellington, New Zealand, observed between January 2006 and April 2015. The datasets are supplementary materials for Vaishnav and Burns (in review, New Zealand Journal of Ecology). The dataset titled "Vaishnav&Burns2025_Dataset_Plants" contains monthly summaries of flower and fruit visitation by native birds to 25 native plant species. The dataset titled "Vaishnav&Burns2025_Dataset_Birds" contains monthly summaries of flower and fruit visitation by eight native bird to native plants. The sheets titled "Summary" in both datasets provide the cumulative monthly counts of bird-flower and bird-fruit visits, and the other sheets provide monthly counts of bird-flower and bird-fruit visits segregated by bird and plant species, respectively. The sheets titled "Not in analyses" are interactions which were recorded in the dataset but excluded form the analysis since there were fewer than three observations for each species per food type (flower or fruit). The dataset titled "Vaishnav&Burns2025_Dataset_Exotics" contains records of flower and fruit visits for non-native birds and plants that were also excluded from the analyses.
