摘      要：Background:To understand the dietary composition of the highly aerial swift(Apodidae),ecologists conventionally depend on the morphological identification of prey items from food boluses or stomach contents,but these techniques are often invasive,require expertise in identification,and often cannot produce accurate identifications at the species ***:DNA barcoding was used to analyse the dietary composition of House Swifts(Apus nipalensis)in Hong Kong,*** samples from five different colonial nest sites were collected between 2019 and *** used universal primers to amplify a region of the cytochrome C oxidase gene from prey DNA in the faecal samples for identification ***:Ten different orders and 44 families from three different classes of Arthropoda were identified in the collected faecal ***,Hemiptera and Diptera were the most prevalent groups of prey found in the *** in the dietary composition of House Swifts during the breeding(April to September)and nonbreeding(October to March)season were also ***,particularly ants(Formicidae),were predominant in the diet during the breeding season,whereas Diptera and Hemiptera were predominant during the non-breeding ***:The prey groups identified in this study were similar to those identified in a previous study of the diet of House Swift,which also suggests a possible role of House Swifts in reducing the numbers of local insect *** study demonstrates the usefulness of applying molecular tools for the dietary analysis of aerial *** local forested areas may be crucial for the maintenance of House Swift population.
