Distribution and biology of Mountain Chiffchaff (Phylloscopus sindianus) in non- breeding period are little known. During observations in Haridwar city (Uttarakhand, India) 7–23.03.2015 we observed two small groups of these birds that kept territories in rose (Rosa
× damascena) gardens. Although gardens were small (0.06 and 0.2 ha) Mountain Chiffchaffs rarely left it for feeding in nearby bushes or trees. Two birds from one group were observed for two days, other three birds stayed on their territory for at least ten days, until 19.03, when the weather became stably hot. We propose that Mountain Chiffchaffs could spend winter in Haridwar. Details of their ecology and social behaviour are discussed in comparision of Sibe- rian Chiffchaff and other warblers.
