Communication When hidden by the foliage, the Syrian woodpecker's presence is often advertised by the mechanical drumming, a vibrating rattle, produced by the rapidly repeated blows of its strong bill upon a trunk or branch. This is not merely a
mating call or challenge, but a signal of either sex. It is audible from a great distance, depending on the wind and the condition of the wood, and a hollow bough naturally produces a louder note than living wood. The drumming is longer than great spotted woodpecker's, and decreases in volume. It is faster and shorter than the drumming of
white-backed woodpecker. The call is a sharp
quit, quit, softer than great spotted woodpecker, and something like
common redshank.
Feeding The Syrian woodpecker's food mainly consists of those
insects which bore into the timber of forest trees, such as the
larvae of wood boring
moths and
beetles. Additional prey includes bees such as
Xylocopa pubescens. The woodpecker usually alights on the trunk, working upwards. During the ascent it taps the bark, breaking off fragments, but often extracts its prey from crevices with the tip of its sticky tongue. Seeds,
nuts and berries are eaten when insect food is scarce. Its actions are jerky, and it hops rather than climbs, leaping forward with one foot just in advance of the other. Usually feeding in a vertically 'heads-up" position, it is not uncommon for the woodpecker to assume a vertically or horizontally upside-down attitude while probing a tree for food. When a space is crossed the flight is easy and undulating. The Syrian woodpecker attacks polyethylene pipes of both sprinkler and drip irrigation systems in Israel. It pecks holes that are 2-10 mm (mostly 5-8 mm) in diameter, and are usually well rounded. Damage to pipes is frequent in plots of avocado, citrus and grapevines bordered by rows of windbreakers, with pipes near windbreaker being the most severely attacked. The holes in the irrigation pipes lead to a fall in the water pressure which in turn reduces the amount of water emitted at various sections along the irrigation line. The reason for birds' pecking at the pipe is not clear.
Breeding The neat, round 5 cm diameter nesting hole, is bored in soft or decaying wood horizontally for a few inches, then perpendicularly down. At the bottom of the shaft, a small chamber is excavated, where up to 11 creamy white eggs are laid on wood chips. The hole is rarely used again, but not infrequently other holes are bored in the same tree. Almost any tree sufficiently rotten is used. The young, when the parents are feeding them, cluster at the mouth of the hole and keep a continuous chatter, but when alarmed slip back into the hole. ==References==
