THE GREY-HEADED IMPERIAL PIGEON.
Ducula badia griseicapilla, Fauna B. I., Birds, 2ud ed. vol. v, p. 204.
The ranges of the various races of this Imperial Pigeon were ill defined prior to being worked out in the ‘Fauna.’ The present form is that found in the North Cachar Hills, though perhaps not quite typical, Sylhet, Manipur, Bengal East of the Bay of Bengal and all Burma South to Tenasserim and East to Annam. In the ‘Fauna' I accepted Muleyit Mountain as an arbitrary limit South, but Robinson thinks the birds of this range should be allocated to the still more Southern race, badius, and this I now accept.
In North Cachar I found this fine Pigeon very common and saw many nests and eggs. Hopwood and Mackenzie obtained others in the Chin Hills and Upper Chindwin, while Harington also found it breeding in the Kachin Hills and Shan States.
It frequents the same deep forest affected by the other races, and there is nothing to note about its nest and eggs differing in any respect from those of the Nepal bird.
In North Cachar I found most eggs were laid in June and July but they commenced to breed in March, while I have eggs taken as late as August. In Burma Harington, Hopwood and Mackenzie took all the eggs found by them in March and April.
One egg only is laid, and twelve average 45.1 x 34.0 mm. : maxima 49.1 x 33.8 and 45.1 x 36.2 mm. ; minima 43.6 x 33.1 and 44.4 x 32.0 mm.
