WILD BIRD WEDNESDAY - Jackdaw

The Jackdaw (Corvus monedula) is a lively, diminutive member of the crow family.  It appears to have totally dark plumage from a distance, but on closer inspection it can be seen that it is dark grey in colour with a lighter grey nape and sides of the neck.  The beak is short and slender, the eyes are a unique pale blue, and it walks with a quick 'jaunty' step , all of which allow this bird to be distinguished from the Carrion and Hooded crows or the Rook.

Males, females and juveniles are similar in appearance.  The name 'daw' for this bird has been used since the 15th century; it is probably imitative of the call, but also means 'simpleton'. 'Jack' is often used for small animals, and, like knave, means rogue, yet it may also be derived from another call, 'tchack' which is a high-pitched, metallic sounding which might account for the ‘jack’ in their name. 

The Jackdaw is a highly sociable species outside of the breeding season, occurring in flocks that can contain hundreds of birds.  Within flocks there is a strict hierarchy, with a head bird. Occasionally the flock makes 'mercy killings', in which a sick or injured bird is mobbed until it is killed.

The Jackdaw typically feeds on the ground, taking insects and insect larvae, young birds, fruit and acorns. This is a playful species, performing aerobatics such as turning over in strong winds and diving; occasionally entire flocks may perform such displays at the same time.

Males and females pair up in their first year of life, but they do not begin to breed for another year; the pair remains closely tied for life.  Nests are usually constructed in some type of crevice, the pair drops sticks into the crevice until some become lodged; the nest is then built on this platform.  This behaviour has often led to chimneys being blocked and even nests, with the Jackdaw present, crashing down into fireplaces.  The pair defend their nest vigorously against intruding Jackdaws.

Four to six greenish-blue eggs are laid and incubated for up to 17 days by the female.  Both parents feed the chicks for around 30 days.

A special name for a jackdaw flock is a "clattering”.

This bird is smaller than both the Rook and the Carrion crow, and is a renowned thief.

Typical Lifespan: 5 years

 Maximum recorded age of a ringed bird - actual age may be greater Maximum Recorded Age: 17 years 0 months 22 days (set in 1980).

Although this is a common bird, I still love watching and photographing them and I hope you enjoyed this post.
