Henry Salt, A voyage to Abyssinia — Appendix 4 (1814)
“ The smaller wing coverts above are of a bright glossy lilac, which in the greater coverts is rather more mingled with brown, so as to reduce its splendour; the ridge of the wing and greater quills of deep blue, which towards the tips becomes greenish. The margins of the inner webs and the very tips are black. The two middle feathers are dingy green; the rest blue, shading into black on the inner webs; the tail itself is square at the end: the legs are strong and pale, claws brown. ”
