When in Tenasserim the late Mr. Davison observed several specimens of a Rock-Martin about the inaccessible precipices on the eastern side of Mooleyit, near its summit. Mr. Hume adds a note:—“He thought it was exactly like C. concolor, but that species is scarcely likely to have occurred there.” It would seem, however, from subsequent events that Mr. Davison was quite right in his identification of the species, for Mr. Fea procured a couple of specimens on the 20th of March at the top of Mooleyit, as recorded by Count Salvadori.
The following additional notes on the nesting of the species have been published since our account of the bird, in Mr. Oates’s edition of Mr. Hume’s ‘Nests and Eggs of Indian Birds':—
“Major C. T. Bingham writes, from Allahabad : —‘On the 13th October I found a nest with two eggs. A mud cup, stuck against a niche in the ruins of an old temple, 3.1/2 inches in depth outside, 1 in depth inside, lined with a few straws and feathers. Eggs pale pinky white, blotched rather than speckled with tiny marks of grey and purple and sepia.’
“Colonel Butler writes :—‘The Dusky Crag-Martin breeds at Mount Aboo in June and July, on the sides of cliffs and hi hollow rocks, sticking the nest to the wall, as do others of the tribe. The nest is usually a half-open cup at the top, similar in composition and appearance to the nest of Hirundo filifera.
“ ‘ On the 20th of August, 1876, I found a nest in Deesa similar to the one already described, but built against a wall under the eaves of a building in the European barracks. It contained two nearly fresh eggs. Another nest in Deesa, in a similar situation, contained three fresh eggs, on the 24th of September, 1875. Another nest on a beam in the verandah of the regimental school, Deesa, 5th October, 1876, contained three fresh eggs.’
“Subsequently he wrote from Belgaum:—‘Belgaum, 13th July, 1879, three fresh eggs ; 11th August, three fresh eggs ; 15th August, two fresh eggs ; 29th August, three fresh eggs ; 21st February, 1880, three fresh eggs ; 15th March, three fresh eggs.’
“ My friend Mr. Benjamin Aitken favours me with the following note:—‘These birds may be seen wherever there is a range of cliffs or a row of dark walls, provided the place is not much frequented by men ; and they always choose the shady side, as far as have observed, to sail up and down. Their old nests are very numerous on the rocks that line the railway-cutting through the Bhore Ghat, and also on the cliffs at Poorundher, the sanitarium 18 miles south of Poona. These nests are placed at from 5 to 12 feet from the ground. I satisfied myself that the Martins were breeding on the top of the Bhore Ghat at the end of May 1871, and on the 9th of June I observed a pair at their nest at the bottom of the Ghat.
“ ‘ At Poona, on the 1st of March, 1871, I saw a nest under a ledge of stone in a well. The old bird was sitting, and, though repeatedly frightened off, only made two or three circles round the inside of the well and returned to the nest.
“ 'The nest was then given up as inaccessible, from distance and other causes ; but on the 20th of the following August my brother went down to the same nest by means of a rope, and found two eggs, on which the bird was sitting. He described the nest as extremely fragile ; it crumbled to pieces on the first touch.
“ 'In June of the same year my brother, Mr. E. Aitken, saw a nest, in which the parent bird was sitting, under the porch of the Club at Poona. Of this he has perhaps informed you himself.’
“Messrs. Davidson and Wendon remark :—‘In the Sholapoor districts it breeds in abundance in the rains and in February. At Egutpoora it was breeding in the verandah of the Engineers’ bungalow in the middle of March and first week in August. At Lanoli on 20th March.’
“Mr. G. Vidal, relating his experiences in the South Konkan, says :—'Common on the coast and for a few miles inland. I have found nests on the cliffs in February, March, and April, and under the eaves of a bungalow in August.’
“Referring to Rajputana in general, Lieut. H. E. Barnes tells us that 'the Dusky Crag-Martin breeds during March and April, and again in July and August. The nest, composed of pellets of mud, well lined with feathers, is deep saucer-shaped, and is generally affixed to the side of a house under shelter of the eaves.’ ”
Colonel Swinhoe and Lieut. Barnes, in their paper on the Mhow district, state that this Martin is a permanent resident and breeds during February and March, and again in October and November.
