Currently, there are serious changes in the environment in Almaty due to the accentuated urbanization processes. The avifauna of the city is experiencing serious stress pressure in this regard, which forces the animals to adapt to new conditions or leave this territory. The last fundamental research on the species composition of the city's fauna was conducted about 3 decades ago. The analysis of information on the birds of Almaty, collected by specialists of the Institute of Zoology over the past 50 years, showed significant changes in the avifauna. 5 categories of bird species were identified: 1) species that have disappeared from the urban fauna, 2) species whose numbers have declined significantly, 3) species that have a tendency to decline in numbers, 4) species whose numbers are stable or have increased, 5) species that are settling.
