يُوءْيُوءٌ

A certain bird (S, K) of prey, (S,) resembling the [kind of hawk called] بَاشَق: (S, K:) it is of the birds called صُقُور, [plural of صَقْرٌ,] as are also the بَازِى and the شَاهِين and the زُرَّق and the بَاشَق: (AHát in TA, in article بشق:) according to Dmr, it is a small bird, short-tailed, the temperament of which is, in comparison with that of the باشق, cold and moist; for it is more patient, or enduring, and heavier in motion: the people of Egypt and Syria, he adds, call it جَلَمٌ, on account of the lightness and swiftness of its wings: (TA:) plural يَأيءِىُ, and, in a verse, يَأيءِىْ. (S.)

Also, according to AA, The head, or uppermost part, of a vessel in which كُحْل (collyrium) is kept: mentioned before as called بُوءْبُوءٌ, which is perhaps a mistake for يوءيوء. (TA.)
