(1742) Cerchneis tinnunculus saturatus.
THE BURMESE KESTREL.
Falco saturatus Blyth, J. A. S. B., xxviii, p. 277 (1859) (Tenasserim). Tinnunculus alaudarius. Blanf. & Oates, iii, p. 428 (part.).
Vernacular names. As in the typical form.
Description. Darker than any other form and the upper parts of the male washed with slate-blue. This wash occurs in all forms of Kestrels occasionally but is only a faint plum-tinge in freshly-moulted birds and is never present to anything like the degree shown in some specimens of this race.
Colours of soft parts as in the other races.
Measurements. wing 243 to 256 mm.; tail 168 to 176 mm. wing 253 to 264 mm.; tail 146 to 179 mm.
Distribution. Yunnan and the Hills of East and Central Burma to Tenasserim. It is also found in the Shan States and Kachin Hills in Northern Burma. Grant found a Kestrel breeding in Arrakan and Kestrels also breed in the higher Chin Hills but the race is not certain. Probably saturatus and interstinctus will here be found to merge into one another,
Nidification. Wardlaw-Ramsay records that it is very common in " Karen-nee where the rocky precipices afford it good nesting places." Harington found a Kestrel, probably this race, breeding in the Shan States.
Habits. Those of the genus. This race is probably only very locally migratory, descending into the adjacent plains during the Winter but not wandering far from the Hills.
