The Red-backed Shrike is a medium-sized shrike with relatively long tail and wings. The male is prominently colored with a black mask around its eyes, a light gray head and neck and a chestnut-colored back. The females and immatures are paler and barred, and lack the black mask.
The Red-backed Shrike is a common passage migrant throughout Israel in spring and fall migration, and a common summer breeder on Mt. Hermon and rare in the northern Golan Heights and the Upper Galilee.
Nests in shrubs, sparse woodland and at the edges of agricultural groves. During migration can be seen on trees and shrubs in all habitats.
The main threat to Red-backed Shrikes in Israel is habitat modification due to development, afforestation and agriculture in the northern Golan Heights, as well as road building, and development of ski runs and other installations on Mt. Hermon. In agricultural areas, the species is probably affected adversely by pesticides, and in wintering and migration areas in Africa by habitat change, desertification and depletion of food sources.
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.

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.
