Summary
A short journey to northeastern Primorsky Krai was undertaken from late May to early June, 2011, in order to collect the material on intraspecific variations in some of passerine birds, such as the Asian house martin Delichon dasypus, the Blue-and-white flycatcher Cyanoptila cyanomelana, the Eastern crowned warbler Phylloscopus coronatus, and other species. It also included a few overview excursions with the aim to reveal the complete species composition of birds on the attended territories. Their results, as regards occurrences of protected bird species and rarely recorded vagrants, were put in the basement of the present note.
