The Pacific Swallow or Hill Swallow (Hirundo tahitica) is a small passerine bird in the swallow family. It breeds in tropical southern Asia from southern India and Sri Lanka across to south east Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands

This species is a small swallow at 13cm. It has a blue back with browner wings and tail, a red face and throat, and dusky underparts. It differs from Barn Swallow and the closely-related Welcome Swallow in its shorter and less forked tail.

The Pacific Swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on a man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is two to three eggs, up to four in Sri Lanka. It is similar in behaviour to other aerial insectivores, such as other swallows and the unrelated swifts. It is a fast flyer and feeds on insects, especially flies, while airborne

Breeding: Resident Pacific Swallows nest on vertical surfaces with overhangs to protect their mud nest (which would disintegrate in the rain). These may be cliffs with an overhang but are often bridges, dams and other man-made structures. But they shy away from humans and prefer unoccupied buildings. They build solid nests out of mud pellets brought by the beakful from puddles and river banks. Combined with dry grasses, these pellets are arranged much like bricks to form shallow cups. These may be lined with dry grass and feathers. At a particularly suitable nest site, they may form large colonies. Usually 3 white eggs are laid. These are long and pointed and have brown spots.
