How do you identify a jackdaw?
An easy way to identify jackdaws is by their light grey nape and pale white iris, which stand out against the black plumage. Juveniles, however, lack the grey nape and are born with blue-grey eyes. Their irises change to brown in the first winter and white once they gain their adult plumage. The jackdaw call is a simple ‘jack-jack’.
What is the difference between a jackdaw and a Daurian jackdaw?
The Western Jackdaw is very similar in morphology, behaviour and calls to the Daurian Jackdaw, with which its range overlaps in western Asia. Adults are readily distinguished, since the Daurian has a pied plumage, but immature birds are much more similar, both species having dark plumage and dark eyes.
Is the jackdaw in danger of extinction?
Jackdaw numbers are thinned on some shoots, but, in the wider world they represent little threat. Corvids are blamed en masse for small-bird losses, yet magpies, grey squirrels, cats, changes in land use and habitat destruction are the major culprits. Indeed, its diet confirms this.
What is a western jackdaw?
The Western Jackdaw , sometimes known as the Eurasian Jackdaw, European Jackdaw or simply Jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and North Africa, it is mostly resident, although northern and eastern populations migrate south in winter.
What was the original name of the jackdaw?
Linnaeus first described it formally, giving it the name Corvus monedula. The common name derives from the word jack, denoting „small“, and daw, a less common synonym for „jackdaw“, and the native English name for the bird.
Why do jackjackdaws stay together?
Jackdaws form strong pair bonds with their mates and are renowned for their devotion towards their partner. Even if they suffer from a few years of unsuccessful breeding, they still stay together, potentially due to the fact that they have invested so much time and energy into trying to raise young together.
