Vernacular names. Rajaliya (Cing.).
Description. Only differs from the preceding race in its smaller size.
Colours of soft parts as in the typical form.
Measurements. Wing 353 to 383 mm.; tail 227 to 260 mm.; tarsus 90 to 98 nam.; culmen 31 to 33 mm. The wings of the two sexed male specimens in the British Museum series measure 363 and 365 mm.
Distribution. Ceylon and the South of Travancore.
Nidification. Stewart, who has taken many of the eggs of this Eagle, records their breeding-season as being from the end of November to the end of March. Nests and eggs are like those of the preceding bird, the latter only differing in being smaller. Twenty-four average 61.3 x 49.8 mm,: maxima 70.3 X 50.6 and 62.8 x 54.1 mm.; minima 57.5 x 45.l mm. Like the Indian Hawk-Eagle, this bird puts up no defence for young or nest but like that bird also is extremely difficult to drive away. Stewart has taken three eggs in one season from the same nest and then left the birds still in possession.
Habits. Those of the preceding bird.
