The Great Crested Grebe is the largest grebe in our region, and can be identified by its long white neck and black-capped crested head. Grebes have an impressive courtship display in which the pair perform a synchronized dance on the water surface. The species feeds on fish, crustaceans, water insects and amphibians.
The Great Crested Grebe is a rare summer breeder in water reservoirs at the Jezreel Valley and the Golan Heights. It also is a relatively common winter visitor and passage migrant in northern and central Israel, particularly at Sea of Galilee (up to 2,000 individuals were counted in winter water bird censuses). Tens of pairs once nested in the Hula Valley and a few pairs nested in the Jezreel Valley, in the northern Jordan Valley, the northern Coastal Plain and the Carmel coast. Nesting gradually ceased after the Hula marshes were drained (during the 1950s). In the 1970s and 1980s, a few pairs of grebes were seen over-summering but there was no evidence of breeding. In recent years, small numbers of Great Crested Grebes returned to breed in Israel and families with young were observed in a number of reservoirs in the Jezreel Valley and the southern Golan Heights.
Medium-sized and large water bodies in the Mediterranean region. Over-winter in lakes, reservoirs, large fishponds and on the seacoast. Breeds in freshwater ponds and reservoirs surrounded by dense vegetation.
No specific conservation measures have been taken for this species to date.
The continued existence of the species as a breeder in Israel depends on the existence of water reservoirs surrounded by extensive vegetation thickets. Therefore, vegetation thickets should be allowed to develop around water reservoirs, particularly in northern Israel.

Current Occupancy Map
Distribution maps
The maps presented here provide visual information on the distribution of species in Israel in the past and present, and the changes in occupancy and nesting density during the comparison period. For further reading
Relative Abundance 2010-2020
Breeding density values as calculated from observation records and expert opinions.
Relative Abundance 1980-1990
Breeding density values are based mainly on the book Birds of Israel (Shirihai 1996).
Occupancy difference 1990-2020
A map that expresses differences in the breeding distribution between the evaluation periods (1980-1990 versus 2010-2020). Negative value - species previously present but is currently absent, positive value - species has not been recorded previously and is currently present, zero - no change in occupancy.
Relative abundance difference 1990-2020
A map that reflects the changes in the relative abundance of the species between the evaluation periods (1980-1990 versus 2010-2020). Negative values - decline in abundance, positive values - increase in abundance, zero - no change in abundance.
