Kneeling winged monster

This mythical, composite animal and the similar one on the opposite side of the doorway are guardian-demons whose repellent ugliness was believed to avert evil. They were created as pillar bases, or architectural supports, inside the Buddhist cave-temple of the northern Chinese site known as Xiangtangshan, which straddles the border of Hebei and Henan provinces. The presence of these guardians beneath a row of Buddha images in Cave 7 at Xiangtangshan signaled their role as protectors of Buddhist Law. 

Cave 7 originally contained at least twenty-four similar sculptures, but they proved so appealing to Japanese and Western collectors that most of them were removed in the early twentieth century for sale. Many museums bought pairs of the guardian figures. Charles Lang Freer purchased only one (in 1916), but the Freer Gallery of Art purchased an additional two in the 1950s, and the gallery was later given two more in the 1970s. Each sculpture is slightly different.

The specific site of these pieces has been clearly known in the West since the 1950s, but when Mr. Freer made his purchase in 1916, he was unaware of where it came from in China and was told the work was slightly earlier than it actually is.
