Biology

Twite is common breeding migrant, in places common winter visitor. It inhabits hilly sands with grass and shrubs, stony steppe with caragana, meadowsweet and dog rose bushes, crushed stony slopes with bushes and sparse vegetation, or alpine belt with stones and Juniper bushes, often not far from water. Spring migration begins from the end of February to first half of March in flocks of several dozen birds, latest birds were observed in early - mid-April. On breeding area it appears in end of March - April. Altaica subspecies breeds in separate pairs, sometimes in 10-15 m from each other. Nests are built on bush, in height grass (Lasiagrostis, wormwood) up to 0.7 m above ground, or on ground pit under grass or bush twig from dry grass stems and rootless lined with rags, hair and feathers. Clutches of 4-6, usually 5 eggs found in end of April – early July, independent juveniles in broods observed from early July. Autumn migration begins from mid – end September, when flocks of 100-200 birds are common at this time. The latest birds leave breeding area in mid-November.
