THE BUFF-BELLIED PIPIT ANTHUS R UBESCENS JAPONICUS AT RANTHAMBHORE,RAJASTHAN, INDIA

摘要

The Buff-bellied Pipit Anthus rubescens breeds in central and western Siberia from Tunguska to Kamchatka and south to northern Sakhalin and the Kurile Islands. Of the four recognized subspecies, A.r. japonicus winters in South Asia (Ali and Ripley 1998; del Hoyo et al. 2004). On migration and in winter it is found in a variety of open, often wet habitats such as damp grasslands, stubble and ploughed fields, meadows, sea and lakeshores, mudflats, river courses, etc. (Alstrom and Mild 2003). Its statusin the Indian subcontinent is variously described as uncommon winter visitor to Pakistan (Kohat, Bannu, and the plains of the Indus south to Karachi), Nepal, Darjeeling, and Manipur (Ali and Ripley 1998), "generally rare" but more frequent in north-central Pakistan (Rasmussen and Anderton 2012) rare in north-western India (Alstrom and Mild 2003; Grimmett et al. 1998), vagrant for Bhutan and recorded twice (Spierenburg 2005) and "probably a rare winter visitor and migrant in Nepal (Grimmett et al. 2000). Very few sightings are shown in the distribution map for the species in the Indian subcontinent (Grimmett et al. 2011; Kazmierczak 2000).
