Translating bird songs and sounds into human terms is an ancient pastime.
Bird words, as said or sung, should soar and glide, or trill musically, or otherwise serve as interpretive sound. Birds which say their own names, such as the chickadee, the killdee (r) and the bobwhite quail, are excluded, since they have become a part of the standard vocabulary.
