I was recently contacted by reader David Severs who used to be the sergeant at Helmsley Police Station when Dad was village bobby of Oswaldkirk in the 1960s. Towards the end of my dad’s police career when he was press officer in the early 1980s, they also had adjacent offices at force headquarters in Newby Wiske Hall.
David writes: “I told him that I had seen an Oxford philosophy examination paper in which the first question was ‘Do birds enjoy singing?’”
He goes on to explain that Dad used this question as a topic for a subsequent column, and so I decided to see if I could find the column in question in his archives. With the help of my team of detectives (my mum and brother) we came across a piece Dad wrote in 2008 on the very subject. It might not be the original column, but nevertheless discusses this topic.
Dad writes: ‘If we think carefully about that query, it is almost impossible to answer because the first question must surely be: What constitutes bird song? And secondly, why do they sing?’
He states that we think of bird song as something musical and melodic, so therefore does the squawking of a herring gull count? Or what about the repetitive call of a cuckoo? Is the quack of a duck or the honk of a goose bird song?
Dad explains that birds sing for specific reasons, such as to attract a mate, to warn of the presence of predators, or to indicate where its territory may be. In other words, it is a tool of communication, so to know if they enjoy it is hard to judge. It’s a bit like asking us humans if we enjoy the act of talking (of course, we could all name at least one person we know who loves the sound of their own voice).
However, according to one study which was featured in The Times newspaper, there is now scientific proof that at times, birds do actually sing just for the love of it. And it is that which prompted Mr Severs to get in touch, as when he read it, it reminded him of his previous conversations with my dad.
The article was prompted by research on starlings that seemed to prove that although singing was a means of communication, there were also occasions where the birds sang just for the pleasure of it. This was termed ‘gregarious’ singing.
Biologist Professor Lauren Riters from the University of Wisconsin-Madison explains that the birds practice the notes in the songs: ‘They try out different songs, they order and reorder and repeat some sequences, they add and drop notes. It sounds a bit like free-form jazz and it’s quite distinct from the structured songs that male songbirds produce when trying to attract mates.’
She goes on to explain that when they sing in this way their brains produce opioids, chemicals which are known for inducing pleasure and reducing pain (the same as are found in the addictive drugs heroin, morphine and fentanyl).
Professor Riters’ team fed the birds low doses of fentanyl, and sure enough, this triggered high rates of ‘gregarious’ singing. They were also able to switch off the opioid receptors in the birds’ brains, and after this, the birds sang less.
When lockdown was at its height and there were very few vehicles on our roads, I really noticed the bird song around me. I liked to think that our feathered friends were thoroughly enjoying an environment free from polluting exhaust fumes, or was it simply the lack of traffic noise that meant that I was more able to hear them?
There are some very tall poplar trees in my neighbour’s garden, and I often see groups of starlings gathered in the highest branches, singing at the tops of their beaks, and they very much look like they are enjoying themselves. And similarly, on my dog walks, there is a particular hedgerow which is favoured by dozens of sparrows. If they don’t notice you coming, they all cheep excitedly and noisily among themselves. As soon as you stop to listen though, they go quiet. It reminds me of a school assembly hall full of noisy children before the head teacher signals for hush.
But are these sparrows singing for fun, or is their noise about something else? I wish I could ask them!

What a fascinating question. Can’t believe I never wondered if birds sing for their own joy. The starling looks exactly like the starlings we have here in Ohio, USA.
I understand they emigrated with our British ancestors along with house sparrows. Starling produce such a wide range of sounds. I think they’re fascinating in spite of the fact some say they sound like squeaky gate hinges.
Oh, if traffic could always be nearly non-existant. That was a perk of the frightening days of shutdowns.
Though the road I live on leads to state parks, a destination when there was no other place for recreation. So the city streets were quiet, our site not so.

Thanks for taking the time to read and comment Penny! Very interesting to hear your experiences from across the pond. I have a new-found respect for the much-maligned starling! Unfortunately our roads are extremely busy again now so the birdsong is more difficult to hear. By the way, you might be interested to know I started a Facebook group in lockdown called Picture That Walk for people to share pictures of their walks and bike rides. We now have members from all over the world, but not yet anyone from Ohio! I’ve seen your lovely pictures so do take a look at the group as I’d love to have you as a member so others can see your wonderful pictures.
