According to Wikipedia, the endangered species breeds in Spain and North Africa, with a larger population in western and central Asia.
The bird was seen by ornithologist Ritvars Rekmanis in Skrunda:
"[..] When I saw the bird, I realized something's not right as it was too conspicuous," he said.
While Kārlis Millers from the Latvian Birds portal told Latvian Radio that the status of the species is unclear, as is its category - whether it's a wild bird or has escaped captivity. The status of the species is being analyzed in other European countries.
