Mesmerising Murmurations on the Mere

Last winter, during our visit to the RSPB Leighton Moss reserve, we were told that if we waited till dusk, we could get to see a very remarkable phenomenon called murmuration by the starling bird. We had to let go the opportunity then as we had to catch our return train around that time.

Then, a few weeks ago, I read on social media that the murmuration can be watched at the WWT Martin Mere. The Mere was hosting the North West Birding Fair during the 3rd weekend of November. So, if we attended the bird fair, figuratively, it would be killing two birds with one stone–have a look at the fair as well get another opportunity to witness the grand spectacle.

It was a very hectic Sunday at the fair, watching the Bird Ringing procedure, followed by some heavy-duty birding and bird feeding activity. The WWT staff advised us we should be at the Harrier hide shortly before sunset, around 4 pm, to get a good view of the starling murmuration.

Eurpoean Starling

Before talking about my experience, let me briefly introduce you to Starlings and murmuration. The European starling, or simply Starling in the UK, is a medium-sized passerine bird belonging to the starling family. From a distance, the European Starling (Starling) may look black coloured but as you get closer, their glossiness with sheen of purples and green will be clearly visible. They are highly sociable birds and move in large flocks. Just as a collection of crows is called Murder, a collection of starlings is called a murmuration!! And we were at the Mere to watch the starling murmuration in action.

Starling murmurations are typically seen at dusk throughout Europe between November and February. During the autumn/winter months, there are higher starling numbers in the UK due to the migration from the colder Northern Europe. Until 1980s murmurations were regularly seen across the UK, but due to the falling starling numbers, it is now restricted to few locations, specifically to the rural areas with reed beds. Though most murmurations comprise thousands or sometimes hundreds of thousands of starlings, there have been some massive numbers as well. In 1999-2000 at the Shapwick Heath National Reserve, a murmuration of more than 6 million starlings was recorded. That would have been something really spectacular!!

It being our first visit to the WWT Martin Mere, we were not aware of the location of Harrier Hide. It was easy to pick up the path as you just had to follow the mass of people who were walking towards it. By the time we reached the hide at 3.45 pm, it was already jam-packed and there was no way we could get a good view from the hide. So we walked out of the hide and went down to the open fields, which were also crowded and contained no less than 500 people. I could see the reed beds some hundred metres away and understood that this would be the roosting ground for the starlings.

The sun was going down quickly, and it was almost 4 pm when I spotted a flock of starlings converging from our left-hand side. Within the next few minutes, we could see the magnificent display of Starling murmuration taking place right in front of our eyes. As the autumn daylight faded away, small flocks of starlings coming in from all directions began to join up, twisting and turning in harmony forming a visual delight. Sometimes they split up and moved into smaller flocks to reunite. With each manoeuvre, we could see hundreds of starlings drop down to their roosting site, only to quickly re-emerge into the sky. A couple of times there were near mid-air collisions between the starlings and smaller flocks of Pink-footed Geese, which flew into their path. This did create some commotion, however, the starlings once again grouped together and went about their action. It was also funny to spot few laggards joining the formation very late in the show and adding to the count. It was a visual treat to watch 50,000 starlings demonstrate unpredictable patterns and acrobatics in the sky.

There is still a lot of debate as to why do starlings form murmurations. The generally accepted theory is that murmurations are an indication or signal attracting all the starlings in the area so that they can roost together. This grouping together not only manages predation risk but also provide shelter and warmth from the harsh weather. But this process of accumulating huge numbers invariably attracts predators. As explained by selfish herd theory, an individual bird within a flock attempt to reduce its predation risk by moving continuously to the centre of the flock. But the centre never stabilises as each individual bird is trying to attempt the same and this perpetual motion leads to this unique phenomenon. To the naked eye, it looked like a swarm of bees.

It is a marvel how thousands of birds know and decide when and where to turn together, in sync. Recent research shows that each starling while flying follows its six or seven immediate neighbours. And they don’t collide or bump into each other due to their lightning-fast reactions and strong spatial coherence. Thus, when a single starling changes direction or speed, the whole flock responds as if the information has spread in real-time across the flock. Beyond theories and conjectures, today hundreds of biologists, sociologists, mathematicians, physicists and scientists across the world are still researching to find the exact reasons behind this unique behaviour by using latest technologies.

Throughout this awe-inspiring performance, which lasted 15 to 20 minutes, there were constant "Oohs" and "Aahs" from the thrilled crowd. The grand show ended, when, with a swoop all the starlings disappeared into the reed beds to get their well-deserved night break. Actually, I felt like clapping and giving a standing ovation to these beautiful birds for providing us with a humbling experience.
