groves.
Food consists of a wide range of items, including carrion, snakes, locusts and other grasshoppers, stranded fish (in coastal areas), grain stolen from bags, dates and other fruits. It is quite fearless when not persecuted but is quick to become wary and shy if too much attention is paid to it. A 2009 Israeli study showed the species to cooperatively hunt lizards, with birds blocking exits while others hunted.
Nesting
The nest is very much like the common raven's, and may be found in trees, on cliffs or in old and ruined buildings. The dwarf raven seems to prefer thorn trees for its nest building. There are usually 4–5 eggs laid and incubated over 20–22 days. The young usually leave the nest by the 37th or 38th day and can fly well by 42–45 days.
Vocalisation
The voice is very similar to the common raven's consisting mainly of croaks, though higher in pitch; and a harsh ''"karr-karr-karr"''. In flight, it will utter a ''"kuerk-kuerk"'' call. Like all corvids, the Brown-necked raven is capable of vocal mimicry, however this behavior is mostly recorded in captivity and, although rarely, in the wild.
