“…The high proportion of kingfisher pellets and nests containing lizard remains, relative to the other identified prey categories, suggests that lizards form an important component of the kingfishers' diet on these islands. Previous studies have also noted the importance of lizard prey items in the diet of both adult and nestling kingfishers (Burton 1998;Blomberg & Shine 2000;Asokan et al 2009;Soud et al 2010). For example, Asokan et al (2009) reported that 24% of whitebreasted kingfisher (Halcyon smyrnensis) regurgitated pellets contained the remains of lizard prey.…”

Dietary analyses were carried out on four species of native birds on Tiritiri Matangi and Motuora Islands, New Zealand, between February 2007 and February 2008. We examined regurgitated pellets of kingfishers, moreporks and swamp harriers, and the faeces of pukeko. Remains of lizards were found in 88% and 43% of regurgitated kingfisher pellets on Tiritiri Matangi and Motuora, respectively. All remains belonged to one species, Oligosoma moco. No evidence of lizard predation was found for the other three bird species. Translocation of lizards to areas supporting a high abundance of kingfishers should take avian predation risk into account.

“…Swiftlet is not particularly selective on their diet composition (insect diversity) but reacts with the food availability (insect density). The higher abundances of the insect will contribute to the most common dietary items of swiftlet ( 28 , 29 , 36 , 38 , 39 ). Therefore, it was found that swiftlet does not consume all the insect orders distributed in any landscapes ( Table 3 ).…”

The diet of insectivorous swiftlet according to the geographical distribution on the landscape was reviewed to provide an explanation to the four clusters formation and the exceptional cases as described above.…”

Background: Edible Bird's Nest (EBN) is famously consumed as a food tonic for its high nutritional values with numerous recuperative and therapeutic properties. EBN is majority exploited from swiftlet houses but the differences in terms of metabolite distribution between the production site of house EBN is not yet fully understood. Therefore, this study was designed to identify the metabolite distribution and to determine the relationship pattern for the metabolite distribution of house EBNs from different locations in Malaysia.Methods: The differences of metabolite distribution in house EBN were studied by collecting the samples from 13 states in Malaysia. An extraction method of eHMG was acquired to extract the metabolites of EBN and was subjected to non-targeted metabolite profiling via liquid chromatography-mass spectrometry (LC-MS). Unsupervised multivariate analysis and Venn diagram were used to explore the relationship pattern among the house EBNs in Malaysia. The geographical distribution surrounded the swiftlet house was investigated to understand its influences on the metabolite distribution.Results: The hierarchical clustering analysis (HCA) combined with correlation coefficient revealed the differences between the house EBNs in Malaysia with four main clusters formation. The metabolites distribution among these clusters was unique with their varied combination of geographical distribution. Cluster 1 grouped EBNs from Selangor, Melaka, Negeri Sembilan, Terengganu which geographically distributed with major oil palm field in township; Cluster 2 included Perak and Sarawak with high distribution of oil palm in higher altitude; Cluster 3 included Perlis, Kelantan, Kedah, Penang from lowland of paddy field in village mostly and Cluster 4 grouped Sabah, Pahang, Johor which are majorly distributed with undeveloped hills. The metabolites which drove each cluster formation have happened in a group instead of individual key metabolite. The major metabolites that characterised Cluster 1 were fatty acids, while the rest of the clusters were peptides and secondary metabolites.Conclusion: The metabolite profiling conducted in this study was able to discriminate the Malaysian house EBNs based on metabolites distribution. The factor that most inferences the differences of house EBNs were the geographical distribution, in which geographical distribution affects the distribution of insect and the diet of swiftlet.
