Figure 3.30 . M icrohabitat structure o f Sedge Warblers and Reed Buntings. T he dashed line shows foraging zone o f the Sedge Warbler (A) and the Reed Bunting (B) in the bush crown. ground, side branches and the lower part of the crown. Sometimes it descends to the ground and collects food at the base o f the trunks. In some cases the bird quickly climbs vertical branches to the middle or upper part o f the crown. Little Bunting. In the Pasvik valley Little Buntings breed in water-logged river gal­ leries where Arctic birch 0.3 -0 .5 m high grows. The birds feed under the subshrubs by slowly moving on the ground and carefully looking for prey. They pick prey items from the ground, trunks and foliage at the sides and above them. Sedge Warbler. The breeding density of the Sedge Warbler in optimal habitats reaches 260 pairs • k n r2. The shape and size o f their territories, like in Reed Buntings, depends on the distribution pattern o f the scrub and is ca. 0.3 ha. 150
