 It mostly breeds in acacia and tamarisk scrub and tall grass , invariably near rivers or other wetlands . The construction and expansion of irrigation canals has increased its habitat in Sindh , and helped it extend its range into the Yamuna floodplain and parts of Rajasthan , India . It may breed around rice paddies and other fields , or human habitations , provided that there is enough cover and suitable nesting sites . In winter , it moves away from its main riverine habitat , and into drier thickets characterised by Salvadora and Capparis bushes , but never moves too far from water .
