Carpophaga pusilla Blyth, J. A. S. B,, xviii, p. 816 (1840) (Ceylon). Carpophaga aenea. Blanf. & Oates, iv, p. 19 (part.).
Vernacular names. Pogonna (Mal.) ; Kukurani guwa (Tel.) ; Maratham praa (Tam., Ceylon); Maha nila goya, Mata lata gaya (Cing.).
Description. Similar to the Indian bird but decidedly smaller.
Colours of soft parts as in the other races. Measurements. Wing 200 to 220 mm. Ceylon birds do not exceed 216 mm. and most are under 210 mm. Southern Indian birds ran up to 220 mm. and overlap with Northern India but there is a vast area between the two races where no Green Imperial Pigeons occur and, as it is neither scientific nor necessary to create yet another race, it is better to retain these birds with pusilla.
Distribution. Ceylon, South-west coast of India from Cape Comorin to Kanara. Jerdon recorded it from the Central Province probably incorrectly and in East and Central Madras its habitat has not yet been properly worked out.
Nidification. Similar to that of the Indian race. In Ceylon it breeds in February and March : in Travancore, February to April, whilst Stewart also found eggs in June ; in Karwar, Davidson and Bell obtained eggs from February to April. Five eggs average 43.4 x 33.0 mm., showing that the eggs like the birds average much smaller than in the other races.
Habits. Those of the species. Like the other races this is a bird of humid dense forests and where the country East and North gets drier and more open they are not found, nor do they appear again until the wet regions of the North and North-east are reached.
