Literature and original materials collected mainly in the 2nd half of XX cent.
are summarized. The Night Heron is a breeding and migrating species in region
of the Ukrainian Carpathians (the Carpathians, the Transcarpathian lowland and
the Prut-Dnestr interfluve). Colonies were found in the Prut-Dnestr interfluve
and the upper Dnestr valley. Some birds during the breeding period and especially
during migrations can penetrate deeply in mountains. In total the Night Heron
was discovered in 70 points of the region. In 78,6 % cases birds were found
during the breeding period, 18,6 % – during migrations, 2,8 % – vagrants. During
the breeding period birds were observed in 24 (43,6 % cases) points of the Prut-Dnestr
interfluve, in 20 (36,4 %) points of the Precarpathians and in 11 (20,0 %) points
of the Transcarpathian lowland. Spring migration goes almost since middle of
March and up to the end of the second decade of April. Average arrival date
for the region is 6.04 ± 2,58 days (n = 14). About autumn migration data are
practically absent. It is probable, that the basic amount of birds leaves nesting
grounds during first half of September. Description of colonies, data about
nest placing, parameters of nests and eggs, building material of nests, breeding
phenology are given in tables. Current situation of the species in the region
is satisfactory. Majority of colonies are protected in ornithological reservations.
