Комментарии:Martin 228, Лексика 174. An expressive root with not quite precise correspondences (like in many bird names). Vocalism is rather hard to reconstruct: in PT we have to assume a secondary delabialization (*buldɨr- > *bɨldur-). Note velar suffixation in several Turkic and Mongolian forms; the PJ form also may go back to *pi̯oltor-ga > *pi̯oltoɣa > *patua.
