The Forest Wagtail Dendronanthus indicus breeds in eastern Wagtail (243 encounters), obtained over 39 years (1979–2017), Asia and winters in evergreen, and deciduous forests in parts from the Chennai (formerly, Madras) area. We found that the of South- and Southeast Asia (Ali & Ripley 1987). In the Indian species occurred in all the months from August through May Subcontinent, it is widely reported to winter in south-western in this area (Fig. 2), and not just during its passage migration— India, and pass through the rest of peninsular India on migration typically September–October for south-bound, and March–April (see Table 1 below). Here we report, based on our records plus for north-bound migrants (Santharam 1980; Kannan 1985, an analysis of eBird (eBird 2017) data, and museum specimen 1987). We cannot attribute much relevance to the peaks in records, that the species winters in all of the southern part of the number of sightings in October and March (Fig. 2) because the peninsula wherever there is suitable habitat, and not just the these data were collected opportunistically during birding trips. south-western portion of the peninsula—Kerala, and the Western We did not standardise the time we spent in the field, i.e., there Ghats. We define ‘winter’ as the period between southward- and may have been more sightings in some months simply because northward-bound migrations—November through February— we spent more time birding in those months. Of significance is when the species is relatively sedentary (after Remsen 2001). the striking temporal pattern of occurrence during August–May. Principal locations in the article are shown in Fig. 1. Relative frequencies of occurrence are covered later in this paper. Most of our records have not yet been uploaded into eBird We also used citizen science data available in the public (www.eBird.org). We compiled all our sight records of the Forest domain on www.eBird.org (eBird 2017) to generate seasonal bar charts and distribution maps. We generated composite eBird bar charts for the Forest Wagtail from the Chennai and Bengaluru (formerly, Bangalore) areas (covered as ‘counties’ in eBird), which are on the eastern coast, and in the center of the peninsula, respectively, and compared them with an eBird bar chart from Kerala state, which is part of the south-western winter range of the species (Fig. 3). We did not include a bar chart for the state of Tamil Nadu because the western part of 70 70 60 60 50 43 50 40 36 35 40 32 30 28 30 24 No. of sightings 23 20 18 20 10 10 1 3 0 Aug Sep Oct DecNov FebJan Mar Apr May 0 NovOctSepAug FebJanDec MayAprMar Fig. 1.

Our more recent records indicate that Forest Wagtails were observed in GNP in all of the five months from September 2016 to January 2017 (n = 27 trips). We generated a distribution map of all winter sightings (November–February) of the species in the peninsula from eBird (Fig. 5). This clearly shows that the species is not restricted to Fig. 3. Seasonal bar charts for the Forest Wagtail in two districts (counties) in east (top panel) and west (bottom panel) of peninsular India, including a bar chart for the state of Kerala the southwestern regions in winter, but is found elsewhere in the overall. The higher green bars show the periods when a species is least likely to be missed, southern half of the peninsula wherever optimal habitat exists. while the narrower green bars show when species is present (or sometimes present), but We downloaded eBird data for a closer look at the frequency infrequently detected (eBird 2017). The first four rows from the top are based on a total of 1 5735, 14052, 10887, and 5391 submitted checklists. Composite image generated and compiled of Forest Wagtail observations (percent of complete eBird from eBird (www.ebird.org) and created August 13, 2017. checklists that reported the species) in all the aforementioned areas, which is the basis of the bar charts discussed above. The frequency of encounters in Chennai and Bengaluru was that state encompasses the Western Ghats, which is part of the noticeably higher than in Kerala state overall and in the top species’ reported winter range. Chennai and Bengaluru are in the two counties in Kerala (Thrissur and Kannur; Fig. 6). Also, the currently accepted passage migration range of the species. The combined frequency in GNP and IIT was also much higher than temporal patterns of occurrence of the species in Chennai, and in the top five Kerala hotspots combined (Fig.
