Phylloscopus collybita

warning Vulnerable
VU (D1)

Contributed: Lior Kislev, Avner Rinot
Update Time: Jan. 1, 2011, 7:39 a.m.

The Common Chiffchaff is classified as a Vulnerable (VU) because of the small size of its breeding populations, estimated at less than 50 adult birds, combined with a regional adjustment for the fact that the population breeding on Mt. Hermon is a marginal population at the edge of the global range of the species. In the previous edition of the Red Book (2002) the Common Chiffchaff was not listed, as it was discovered breeding on Mt. Hermon only in summer 2013.

The Common Chiffchaff is a slender, small greenish-brown insectivorous bird that inhabits thickets. It has dark brown upper parts, a white belly, black legs and a light yellowish eyebrow (supercilium), over a black eye-stripe. It spends all its time in trees and shrubs and is difficult to observe. Their loud whistling calls give their location away in forests and woodlands.

A common passage migrant and winter visitor throughout Israel. In recent years they have been found breeding on the Mt. Hermon slopes, in areas with well-developed Mediterranean woodland, at altitudes of 1,300 meters. An estimated 20 to 40 pairs breed on Mt. Hermon (Israeli & Perlman 2013).

No specific conservation measures have been taken for this species to date.

Occupancy 1990-2020

The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.
