Comparison of nest site selection of Orthotomus sutorius and O.cucullatus
Nest site selection and nest characteristics of Common Tailorbird (Orthotomus sutorius) and Mountain Tailorbird (O.cuculatus) in Nonggang, Guangxi, Southwest China, were compared in the breeding season from March to June 2013-2014.A total of 64 nests of O.sutorius and 47 nests of O.cuculatus were found.Among them, 60 nests (93.7％) of O.sutorius were located in the forest nearby village, while 44 nests (93.6％) of O.cuculatus were found in the forest at the mountain foot and far from village.The principal component analysis indicated that the main factors for nest site selection by O.sutorius were height of nesting trees, distance to forest and altitude, whilst the main factors for O.cuculatus included height of nesting trees, visibility around nest and distance to mountain.Linear discrimination analysis showed that distance to mountain plays the most important role in nest site selection for the two tailorbird species.
