361. Aethorhynchus lafresnayi innonota

(361) Aethorhynchus lafresnayi innonota Blyth.
THE NORTHERN GREAT IORA.
Aethorhynchus lafresnayi, Fauna B. I., Birds, 2nd ed. vol. i, p. 338 (part.).
* Kloss gives the restricted area for the Northern form, Ae. I. innonota, as South Arrakan to about latitude 8°, the typical form, Ae. I. lafresnayi, extending South from this throughout the Malay Peninsula.
There is nothing on record about the breeding of our bird, but Kellow took two nests of the Southern form near Simpang, in the Malay States. The nests, two eggs and birds were sent to me and later two other eggs.
The nests were all three built in bushes in evergreen forest, near the outskirts, at heights of three to five feet from the ground. The bushes also had nests of red ants on them, the ants swarming everywhere and making it very difficult to get at the nests. These were just like those of the Common Iora but rather bigger, more bulky and less tidy, though the packing and travelling may have had something to do with this. They measure, roughly, about 3.1/2 inches across by 2 deep externally, and are made entirely of soft grass and vegetable fibre matted over everywhere with spiders’ webs. The three nests all seem, from the marks on them, to have been placed in upright forks or clusters of twigs.
They were taken on 4th January, 27th March and 16th June, so the breeding period would seem to be very indefinite for the Southern bird.
The eggs sent me are typical Ioras’ eggs. In both clutches the ground is white ; the primary markings consist of longitudinal blotches of brown, very long in one set, rather shorter and more reddish in the other. The secondary markings are similar in character but pale grey in colour, having a violet tinge where they show through the brown ones. Both markings are most numerous at the larger ends, where they form rings. In shape one pair are ordinary ovals, the other rather short, broad ovals. The texture is fine and smooth but not glossy.
One pair measure 17.3 x 14.1 and 17.3 x 14.4 mm. ; the other pair 18.7 x 14.0 and 18.9 x 14.3 mm. Although over the average size for the Common Iora, these eggs seem very small for the Great Iora, and Kellow informs me that two eggs kept by him measure 20.2 x 15.3 mm.
