The Pied Avocet is a larger wader with a distinctive appearance: contrasting black and white plumage and an up-curved black bill. Its preferred habitats are marshes, riverbanks and lakes. Can also be found in coastal lagoons and inundated fields. Uses its long legs to walk and swim in the shallow water, sweeping its bill from side to side to catch invertebrates with its distinctive bill.
The Pied Avocet was mentioned by Tristram as a resident species in Israel in the 19th century. The first confirmed record of breeding was from the Atlit saltpans in 1961. During the 1970s and 1980s, 1-20 nesting attempts were recorded annually in the Northern Valleys and the Coastal Plain, most of which ended in failure, probably because of rapid fluctuations of the water level in fishponds and reservoirs. The last nesting attempts were recorded in the early 2000s; since 2002, however, no breeding pairs have been seen.
All the Pied Avocet nesting attempts observed in Israel took place in artificial water bodies, such as saltpans, emptied fishponds and reservoirs. These habitats are characterized by rapid fluctuations in their water level, which harms nests and eggs. In addition, the species is probably affected by increased predation pressure by eruptive species such as crows, mongooses and jackals that are known predators of ground-nesting birds.
The Pied Avocet has been extinct as a breeder in Israel for the past two decades. According to existing data, the species nested in Israel intermittently and in small numbers, mainly due to the formation of temporary habitats in fishponds and reservoirs. It is highly probable that the Pied Avocet will return to breed in Israel naturally.

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.
