Noisy, animated, intelligent and occasionally quarrelsome jackdaws are real characters of the bird world, making their presence felt wherever they go with their distinct ‘chack’ call which cuts through the air.
The Jackdaws’ bright blue eyes are particularly striking and looking into them you really feel as though you are being watched by a very intelligent creature.

Their curious nature and relative confidence around humans makes it easy to photograph these birds and capture some of their interactions. The Jackdaws here in Aberystwyth are no exception, and by spending considerable time with them over the months and years, this particular flock has become accustomed to my presence making studying and photographing their behaviour relatively easy.
Whilst the flock foraged for insects in the grass today, I took the opportunity to capture some of their social behaviour in pictures.

Jackdaws are highly social birds, living in small flocks using consisting of several mated pairs and a few unattached birds. Jackdaws are one of the few birds that is truly monogamous and pairs will regularly stay together until one bird dies, with matings outside the pair very rare indeed.
Pairs tend to stick close together when feeding, often segregating themselves from other members of the flock.

Although usually fairly amicable towards one another, Jackdaws follow a strict hierarchy, particularly when it comes to access to food and nests. More dominant pairs will feed first and see off other subordinate birds with a variety of subtle behaviours and signals.
Relaxed or appeasing Jackdaw will have sleek, flattened feathers, usually with the beak pointed slightly upwards.

The first sign of any animosity usually involves a bird raising it’s head feathers to show off the grey nape towards another individual.

A more threatening version of this display occurs whilst pointing the beak downwards. This instantly makes the individual appear larger and more intimidating to its rival.

If the bill-down display does not have the desired effect the Jackdaws may then thrust their beaks towards one another with the tail spread in a forward-threat display.
Fortunately displays of this kind is usually enough to settle a dispute and the lower ranking Jackdaw will retreat before a fight occurs.
