When I first saw this stamp, I thought it might show the Madagascar Scops Owl (Otus rutilus).  However while checking in "Birds of the Indian Ocean" I noticed the other owl found on the island with ear tufts, the Madagascar Long-eared Owl (Asio madagascariensis) had a call which was described as 'Kahaan-kahaan-Kahaan'.  In "Birds of Prey of Africa and its Islands" (Kemp & Kemp 1998) the call is described as 'han-kan han-kan han-kan' and the same illustration, by Peter Hayman, is used but is much more rufous than the one above.  I suggest that the bird is named locally after its call.

Does anyone have a further comments for the "Hanka"?
