A viral video shows a rare sighting of two black wolves crossing a stream in an undisclosed forest in Poland. The black wolves shown in the video are believed to be siblings.

The video footage, released on SAVE Wildlife Conservation Fund Poland's Facebook page on February 4, compiles two clips from the wildlife camera. The first shows a black wolf slowly padding through the stream before jumping onto the bank, followed by a gray-colored wolf. The second clip shows two black wolves crossing the stream.

A wildlife conservation group in Poland was conducting research on beavers when they spotted two rare black wolves on video footage captured in a forest last year.
