%X Many years ago, ornithologists from the Central Asian republics, Kazakhstan, and Western Siberia joined forces to study bird migration. During this period, we have traveled a long road, from developing unified research principles to applying the resulting conclusions to solve a variety of practical problems.The study of bird migration across the vast territories of the Central Asian-West Siberian region is a complex and challenging task. This region encompasses several landscape zones and exhibits extremely diverse natural conditions. Nevertheless, thanks to the participation of numerous researchers from different areas, many problems have been successfully addressed. This volume is the fourth in a series of collections and reflects observations conducted in Southern Central Asia, the Issyk-Kul Basin, the Alay Valley, the lower reaches of the Ural and Turgay rivers, Central Kazakhstan, the Altai region, and other areas.As with previous joint publications produced by participants in regional studies, the materials included in this volume give us reason to believe that certain skeptical views regarding visual observations have been greatly exaggerated. Certainly, the scattered and unsystematic visual observations of the past were unable to reveal many of the patterns of bird migration. However, comprehensive studies carried out simultaneously across extensive territories according to a unified methodology have elevated this approach to a new level. Whether used independently or in combination with large-scale trapping and bird-banding methods, visual observations can serve as a basis for assessing the spatial distribution, migration direction and dynamics, and population fluctuations of migratory birds.Particular attention should be paid to two papers in this volume concerning bird migration in the lower reaches of the Yakhsu River in Tajikistan and in the Surkhan River floodplain of southern Uzbekistan. These two studies, conducted in geographically adjacent regions,
