This paper considers the dates of arrival of the grey crow at the latitude of the Arctic Circle (the city of Labytnanga) for the period 1970–2016. The dynamics of the dates of arrival of the grey crow were revealed to have stable long-term trends of different directions, which reflect different climatic events that took place in these years. The dates of arrival of the grey crow were found to be correlated with the dynamics of the average temperatures in April and the average daily temperature on the day of the onset of migration with a delay of 1–2 years. It was established that the lower the air temperature in the previous spring, the earlier the first crows arrived.
