(764) Artamus leucorhynchus humei Stresemann.
THE ANDAMAN WHITE-RUMPED SWALLOW-SHRIKE.
Artamus leucorhynchos humei, Fauna B. I., Birds, 2nd ed. vol. ii, p. 350.
This Swallow-Shrike is confined to the Andamans and the Great and Little Cocos Islands.
The only account of this bird’s nesting in Hume’s ‘Nests and Eggs’ is the finding of an empty nest by Davison on the top of a rotten Mangrove-stump on the 2nd May:—“The nest was built entirely of grass, somewhat coarse on the exterior, finer on the inside ; it was a shallow saucer-shaped structure placed in the hollow at the top of the stump.”
In 1905 Osmaston found this bird breeding very freely, and thus, records his observations (Journ. Bomb. Nat. Hist. Soc. vol. xvii, p. 157, 1906) :—“Common in open places and in clearings round Port Blair. They appear to be very affectionate, the male and female sitting for long periods side by side on the same perch. They are fearless of men and follow anyone about, snapping up the grasshoppers and other insects which are disturbed into flight. They breed in April and May, the nests being almost invariably placed on the broken-off stump of some stout branch of a tree from 10 to 20 feet from the ground. Jack-fruit trees are frequently selected as building sites. The nest is an untidy shallow saucer of twigs, little better than a dove’s nest. It is usually quite exposed to view from above and more or less also from below. The parent birds are very bold and defend their property with much spirit. The full complement of eggs is three. They are white, spotted with light brown or fawn, chiefly in a zone, with numerous under¬lying grey markings.”
In 1906 and 1907 Osmaston obtained a very fine series of eggs of this bird, which are now in my collection, but the only note I can add to his, given above, is the fact that he took one nest at a height of 25 feet from the ground. His series was taken between the 20th March and 5th May, but Wickham obtained a nest with one egg on the 4th June, probably a second laying.
Forty eggs average 23.8 x 17.2 mm. : maxima 27.0 x 18.9 and 25.6 x 19.0 mm. ; minima 22.3 x 17.1 and 23.0 x 16.5 mm.
The maxima are from a clutch of three all abnormally large and, excepting these, the maxima are 24.7 x 18.0 mm.
