• Changes in the timing of bird migration can be tracked if there is data on the timing of bird migration collected by the same methodology. Bird ringing is a source of such data. The combination of two methods of registering migration parameters—observation and catching—provides more accurate data on the first meeting of migratory species in the study area. This article deals with three parameters of spring migration: the first registration, the median of migration, and the last registration of the species (average values for 2015–2018) for 48 species of migratory birds according to capture and observation data around the Baikal Bird Ringing Station (the southeastern coast of Lake Baikal). A comparison of the dates of the beginning of spring migration for 17 bird species in some areas around Lake Baikal (Irkutsk oblast and southeastern and northeastern coasts of Lake Baikal) showed that 13 bird species arrive on the southeastern coast 2–20 days earlier. It is determined that changes in the dates of the first registration between years are insignificant for 13 species of birds (+/–3 days). These species are most promising for the long-term monitoring of climate and population changes.
