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.

Change in Relative Abundance 1990-2020
The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
