THE DUSKY CRAG MARTIN.

Length, 4.6 ; wing, 4 ; tail, 2.

Smoky brown, slightly paler, and with a reddish tinge beneath ; a round white spot on the inner webs of all the tail-feathers, except the centre and outer pairs; the tail is nearly square.

The Dusky Crag Martin, with the exception of Sind, occurs more or less abundantly throughout our limits. It is somewhat solitary in its habits, rarely more than a single pair nesting in the same vicinity. They have apparently two broods in the year, and lay at different seasons in different parts of the country, but from January to March, and July to September, are perhaps the best months to search for eggs. Its nest, affixed to projecting eaves or ledges of rock, is very like that of H. filifera, but is smaller more cup-shaped, and pointed at the bottom, but, like it, is well lined with feathers; the eggs, three or four in number, are white with numerous spots and specks of various shades of yellowish or reddish-brown, but these markings are neither so bright, or so bold, as those of the Wire-tailed Swallow; they average 0.72 in length by 0.52 in breadth.
