Abstract: The article focuses on the occurrence of the Pallas’s Sandgrouse in Poland in 1863–2013, on the basis of ornithological literature, hunting magazines and daily press. Three large invasions of the species were observed in Poland in 1863, 1888 and 1908; otherwise, it was observed only ten times. In the course of 150 years, 281 records were noted in all regions of the country. Most of them came from the former Prussian Partition, while the fewest – from the Russian Partition. Three breeding cases were recorded in the Greater Poland and Pomerania, and there were two cases of probable nesting. The birds were predominantly observed in the flocks of 10–80 individuals (N=99), while the groups of several hundred birds were rarely recorded (N=14). Three main invasions happened in April and May; 89% of all observations come from 1888.
