1	Study of Breeding Biology and Habitat Use of Black-naped Oriole (Oriolus chinensis) Chu, Li-ching 13 February 2007 (has links) Black-naped Oriole (Oriolus chinensis), Oriolidae, Passeriformes, is a member of old world songbirds. It has a wide distribution all over the eastern Asia, and is divided into 18 to 20 subspecies by differences in breeding sites, residents or migrants, morphological characters and songs. The populations breeding in Taiwan are classified as subspecies Oriolus chinensis diffusus. Black-naped Orioles inhabit in wooded habitats with a preference for tall secondary forests and disturbed wooded habitats and the staple foods of Black-naped Orioles are fruits, larvae, pupae and imagines of insects. This study was intented to understand the habitat preference and to explore the fundamental ecological data of Black-naped Oriole in Taiwan. Breeding seasons of Black-naped Oriole started from March and ended in July, and reached its peak from April to June. Most of the birds had two broods each year. Females built nests and incubated for 17-21 days alone, and males shared feeding and protecting juveniles after hatching. The birds of Pingtung population often built their nests on tall Albizia falcate and those of Fenglin population on Pachira macrocarpa. The breeding success was 23.3% in Pingtung and 18.2% in Fenglin. The breeding failure were due to human disturbance, climate, and poaching. The materials used for nest were bark, grass, leaves, and some artificial materials. Black-naped Orioles prefer to build nests at the same tree but on different branches. The nests were often closed to nests of Dicrurus macrocercus. Cooperative defenses between these two birds were observed. breeding success breeding biology habitat preference Black-naped Oriole
2	Taxonomy of the Rufous-naped lark (Mirafra africana) complex based on song analysis Nymark, Marianne Kristine January 2021 (has links) The Rufous-naped lark Mirafra africana complex consists of 22 subspecies spread across the African continent. Several of the subspecies have recently been suggested to potentially be treated as separate species. In this study a comparative analysis was done on the song from seven of the subspecies: M. a. africana, M. a. athi, M. a. grisescens, M. a. kabalii, M. a. nyikae, M. a. transvaalensis and M. a. tropicalis. The results showed that M. a. athi, M. a. kabalii and M. a. nyikae are all very divergent from each other as well as from the other four subspecies. In contrast, M. a. tropicalis, M. a. grisescens, M. a. africana and M. a. transvaalensis are not clearly separable from each other. Based on the results, I suggest that M. a. athi, M. a. kabalii and M. a. nyikae can be classified as separate species, with M. a. africana, M. a. tropicalis, M. a grisescens and M. a. transvaalensis forming a fourth species (M. africana sensu stricto). Finally, I conclude that this study shows that more studies need to be done on the subspecies of the Mirafra africana complex. rufous-naped lark mirafra africana systematics taxonomy ecology zoology song analysis subspecies integrative taxonomy clinal variation LDA post hoc Tukey HSD test Raven Pro Zoology Zoologi Ecology Ekologi Biological Systematics Biologisk systematik
