Graphical summary of the nine prey groups identified from 163 faecal samples of House Swifts containing identifiable prey DNA, collected from five different nest sites in Hong Kong between 2019 and 2020. a the frequency of occurrence (%FO) of different prey groups in all 163 faecal samples; b the normalised percentage of clones (%C) of different prey groups in all 163 faecal samples
Graphical summary of the prey groups identified from House Swift faecal samples collected at CUHK and all five nest sites between 2019 and 2020. a and b show the frequency of occurrence (%FO) of the six major prey groups in samples collected at CUHK and all five nest sites, respectively; c and d show the normalised percentage of clones (%C) of different prey groups in samples collected at CUHK and all five nest sites, respectively
Two-dimensional NMDS representing Bray-Curtis distances between different prey groups of House Swifts identified in faecal samples collected at CUHK nest sites and all five sites during the breeding and non-breeding seasons
Percentage contribution of different prey groups to the dissimilarities between the breeding and non-breeding seasons. a The percentage contribution of samples collected in CUHK only. b The percentage contribution of samples collected from all five nest sites
