No. 37. Spizaetus Kieneri, Desparre.
The Rufous-Belled Hawk-Eagle.
Nothing is known of the nidification of this species, I myself have never even seen a specimen.
Mr. E. Thompson, (whom I look to for specimens) remarks, " I enter this bird here because I have seen it come in at the end of April and remain for some time on the lower well wooded hills.
It has a rapid and elegant flight, mounts well, better than S. Caligatus or S. Nipalensis, which soar very awkwardly. Its cry is also somewhat different from the latter, and resembles a chirrup more than a clear metallic note."
Mr. Wallace has the following brief note on this species (Ibis 1868).
" Spizaetus Kieneri, Gervais, Mag. de Zools. 1835, Ois. pl. 35; Schleg. Mus. P. B. Astures, p. 11.
Sab. Borneo (Wall.) ; Philippines ? (Mus. Lugd.); India (Jerdon).
I obtained a single specimen of this small Eagle in Borneo. It had seized a Pigeon, which it was devouring when I shot it. Wing, 13 inches, the point, 4 inches; tail, 7.5 inches; tarsus, 2.5 inches; middle toe, 1.625 inch; inner toe, 1 inch."
