Tons of of pied wagtails collect each night within the London Aircraft bushes exterior Marks and Spencers – proper above the heads of the consumers. Drawn by the heat generated by the lights of the town, these small black and white birds flit about overhead, chittering noisily and wagging their lengthy tails in an enormous communal gathering earlier than settling all the way down to roost. At first look they appear like Christmas decorations hanging within the bushes.
Like the consumers, these tiny birds come from miles round for this annual winter get collectively. They flock collectively above the road lights the place it’s hotter and, once more like the consumers beneath them, tuck into additional snacks out there – of their case snacking on the bugs which are additionally drawn by the heat of the town centre.
Conserving heat below the town lights
Pied wagtails weigh on common simply 21g and in the course of the chilly winter nights can lose as much as 20pc of their physique weight. So huddling collectively right now of yr is an important survival approach. I noticed them for the primary time some years in the past whereas I used to be late evening purchasing with my spouse in York. We arrived simply as nightfall began to fall and seemed as much as see a flock of greater than 20 on prime of the roof of Marks and Spencers.
It wasn’t lengthy earlier than a second after which a 3rd giant flock joined them. These elegant birds wish to roost communally in order that they will hold heat and these big congregations are fairly sociable events for them. In a short time there have been greater than 200 pied wagtails noisily chittering amongst themselves as the consumers under them walked previous seemingly oblivious.
Drama within the skies above
As I watched the birds, I seen the sound of their affable track change tone. What had been a straightforward, social chit chat become greater, faster-pitched, noisy calling. The flocks started flitting uneasily from one rooftop to the following as they let loose these sharp warning sounds. Then I realised why. A sparrow hawk all of a sudden appeared out of nowhere and instantly set to, chasing wagtails earlier than him. There was chaos within the sky because the black and white birds flew and swerved in all instructions.
Some wagtails even dared to strive chase the hawk away and the tactic labored monetarily as after some time the hawk retreated. The wagtails, now
all grouped collectively in a single flock, settled uneasily again down onto the roof of Marks and Spencers.
Sparrowhawk assault
However earlier than lengthy the hawk was again. It flew flat out throughout the facia of the Halifax financial institution constructing, banking away when it was simply inches away from the wall. Because it flipped up over the roof prime, clouds of pied wagtails took to the air. Once more the hawk did not catch a wagtail. However then on the third fly-by it was profitable and plucked one from the flock with its sharp talons.
The wagtails have been very flighty after this aerial assault and flew round frantically, touchdown on completely different roof tops intermittently earlier than lastly selecting prime of Barclays financial institution. Then after they thought the hazard had handed the flocks swooped again down into the London Aircraft bushes that line this in style purchasing avenue and ultimately settled all the way down to roost for the evening.
The noise of all of the birds throughout this aerial assault had been unimaginable – in my view the scene wouldn’t have seemed misplaced on a Planet Earth II episode – and but not one of many a whole bunch of individuals on the street under even seemed up! I used to be surrounded by people and felt like shouting out, ‘Wow did you see that!’ however thought higher of it. The patrons, focussed on their very own world, had missed this unimaginable drama within the sky going down proper above their heads within the centre of York.
Pied wagtails start to congregate at 3.30pm and are often settled into the roost by about 5pm. Take binoculars in case you are going!
