Distribution and population
Collocalia leucophaea breeds only on Tahiti in the Society Islands, French Polynesia, where it was recorded in five valleys in 1971-1974 (Holyoak and Thibault 1984), and in six valleys (out of 39 visited) during the period 1986-1991 (Monnet et al. 1993), apparently never having been abundant in the 20th century (Holyoak and Thibault 1984). Indeed, in 1923, it was noted that two local hunters travelled for eight days through the valleys without seeing this species (Beck 1923). In 1997, a new breeding site, with c.30 nests, was found (P. Raust in litt. 1999, C. Blainvillain verbally 2000). A population of c.100 birds is monitored regularly in Papehue valley and appears to be stable (P. Raust in litt. 2007). The global population is estimated to be below 1,000 birds and stable. It was formerly encountered on Huahine and (possibly) Bora Bora, while records from Moorea in 1973 may have referred to vagrants from Tahiti (Holyoak and Thibault 1984, Monnet et al. 1993, P. Raust in litt. 1999, 2012).
It prefers wet, rocky and forested valleys at high elevations (Pratt et al. 1987). It nests either in shallow depressions under overhanging rocks and coastal cliffs, or caves (Pratt et al. 1987, Chantler and Driessens 1995).
Its rarity is possibly linked to the introduction of the Common Myna Acridotheres tristis (Holyoak and Thibault 1984) (which is known to defend territories, tree hollows and other nesting sites from native birds) and Swamp Harrier Circus approximans (C. Blainvillain verbally 2000). Other introduced species may have a negative impact on Tahiti Swiftlet.
Conservation Actions Underway
The population at Papehue valley is monitored regularly. Conservation Actions Proposed
Protect the known breeding sites (P. Raust in litt. 1999). Survey for other breeding sites. Continue and expand monitoring of known populations. Identify nest predators and take protective measures as necessary.
