Author interview with Michael J Warren: The Cuckoo’s Lea

Weaving together early literature, history and ornithology, The Cuckoo’s Lea takes the reader on a journey into the past to contemplate the nature and heritage of ancient landscapes. It explores the stories behind our placenames, alongside historical accounts of bird encounters thousands of years ago, their hidden secrets, the nature of places and more. 

Michael J. Warren is a naturalist and nature writing author who teaches English at a school in Chelmsford. He was an honorary research fellow at Birbeck Colledge, curates The Birds and Place Project, and is a series editor of Medieval Ecocriticisms. We recently had the opportunity to speak to Michael about The Cuckoo’s Lea, including how he first became interested in birding, what he discovered throughout his research for this book and more. 


Firstly, can you tell us a little bit about yourself, and how you became interested in birds and birding?

Professionally I do many different things, but birds, the natural world, conservation and environmentalism are central to all of it. I’m an English school teacher as well as an academic working in the environmental humanities (my PhD was on birds in medieval poetry), so literature, language and history are always intertwined with my love of nature and nature writing. I was formerly chair of the New Networks for Nature group and am currently a trustee for the charity Curlew Action, where I advise on education as it relates to the forthcoming Natural History GCSE. 

I’ve been into birds and birding for as long as I can remember, having been encouraged by my uncle and aunt who are both keen naturalists themselves, but most of all I was inspired by my parents as they did one of the best things I think any parent can do for a child – they educated me in the great outdoors. By which, I meant that all our holidays were in various wild locations across the UK, involving ramshackle cottages in remote valleys and by secluded rivers, from which my brothers and I were free to roam, exploring and playing each morning. I have a deep passion for British landscapes and wildlife, and I am who I am today because of those early experiences. They shaped me profoundly, and I’m now trying to do the same with my two daughters (which is working so far, but they’re still young and impressionable right now!) 

What inspired you to write a book on the history of place names with avian origins? 

Initially this idea came from my academic research on birds in medieval literature and culture. When I started to explore the presence of bird species in place names in the realm of medieval studies by default as most English place names are Old English in origin and can be traced back to the Middle Ages – I was astounded by just how many there were. I knew there was something really fascinating to examine, including what these names could tell us about people’s ecological knowledge and relationships over one thousand years ago. Every name is a story. 

One of my reviewers has kindly described The Cuckoo’s Lea as a ‘Rosetta stone for our ecological knowledge’, but it’s the place-names that are the stone. They provide us with a portal into the imagination of early people who were encountering and interacting with these environments. I realised that placenames were the perfect subject for my first narrative nonfiction book as it combines birds, landscapes, medieval history and ecological history, while also providing the opportunity for me to travel to different places, experience them first hand, and collate all these elements into a personal narrative with broad appeal.

Each chapter focuses on a different location and species across the UK. How did you decide which areas to focus on and which of the many species that reside there to highlight?

I went back to the drawing board a lot with that one! 

I wrote this book alongside becoming a father: six years of raising two daughters through those early years combined with six years of research, travel, and writing at 4am in the morning because that was the only way to carve out writing time until I got my book deal with Bloomsbury. As such, practicality determined a lot of it I travelled to locations I could feasibly reach within my budget (at one point we were living on my part-time salary and my wife’s statutory maternity pay) and the restricted time available. Under other circumstances I would have liked to have travelled farther afield for the book to Ireland, for instance.  

My selection was also determined by the range of species that I thought would most appeal to readers. So, although there’s a danger of over-featuring certain birds in nature writing, I knew I had to include cuckoos, cranes and nightingales in the book because everyone loves them! These three species were also popular in medieval culture too, so it made sense to feature them, and I lived in Cranbrook (Kent) for most of the time I was writing the book, so that provided an obvious starting point. 

I also thought hard about the range of ideas I wanted to explore relating to how birds evoke and define place for us and allowed this to lead me towards particular birds and/or places. For instance, I wanted to write about the soundscape of birds as a phenomenon that both animates or shapes place a recurring idea in the book. This meant that owls became important as, to me, they exemplify this enthralling idea that our ancestors naturally and happily recognised bioacoustics as distinguishing properties of a place’s atmosphere. Finally, and again practically, it was also imperative to have some geographical range to my adventures so any reader would be able to read about somewhere in their home county or a nearby county. 

What was the most surprising discovery you made whilst researching this book? 

I think it was the sheer number of species represented in Old English placenames.  

I don’t think you would expect birds to turn up so frequently in placenames, given that you’d want a place-marker or identifier to be reliably solid, present and static and birds don’t tend to remain static much of the time. Some of the species that can be found in our placenames, such as swallows and cuckoos, aren’t even in Britain for much of the year! On this basis, wrens, buntings, snipe, dunnocks and sparrows aren’t species I expected to find. 

There’s also nowhere that really matches the range of species in English placenames. Gaelic does have a good range across both Ireland and Scotland, but it’s difficult to trace the origins of the names beyond the 19th or 18th centuries as the cultures were oral, so names often weren’t recorded until the first OS maps were produced. 

On the flip side, I was also surprised by the species that aren’t in our place-names nightingales, for instance. This species was highly prominent and celebrated in both medieval art and poetry, and would have been much more populous than they are today, so how is it that they didn’t find their way into placenames? (That doesn’t stop me having a chapter on nightingales, by the way.) The same goes for corncrakes. There was an Old English name for the bird, and their calls would have undoubtedly been an unavoidable and loud sound of summer throughout the land. Herons only appear once or twice, and, perhaps most surprisingly, the robin (or ruddock in Old English) doesn’t feature at all!

Finally, can you tell us what you’re working on at the moment? 

Right now, I’m focused on making a success of The Cuckoo’s Lea! 

Alongside booking readings, signings and talks, I’m also creating a website titled The Birds and Place Project (birdsandplace.co.uk) which aims to record the birdsong of all the species mentioned in English placenames which is quite an undertaking! It will be a lifelong project as I’d like to extend it beyond England and the English language to include other countries and languages found across Britain and Ireland. I see it as an extension of my book; and as a site for anyone to find out about this fascinating, but currently little-known, aspect of our natural history and heritage. 

Beyond that, I’ve got my eye on my second book, provisionally titled Hibernal: The Obsessions of a Justified Winter Lover. I’m a serious winter fanatic, so I’ve known for some time that my second book will be a meditation on my favourite season. It will be an emotional and personal journey into my obsession with winter, including encounters with those living and surviving the season in the far north, as well as those who can’t stand winter and suffer terribly in the darkness and cold. Plus, it will highlight historical stories about the importance of winter, how previous times and cultures coped with it, and discuss how winter as a season is changing because of climate change. I don’t think there’s much chance of me commencing this book in 2025, but then again, if this book is going to take me another six years, I can’t waste a single winter…

This Week in Biodiversity News – 2nd June 2025

Wildlife 

Poole Harbour’s osprey pair have hatched their fourth chick of the year. The only breeding pair of ospreys on the South Coast have laid a clutch of four eggs for the second year running, and the Birds of Poole Harbour charity has announced that the final chick successfully hatched in the past week. In 2022, female CJ7 and male 002 became the first nesting pair on the south coast in 180 years as part of a reintroduction scheme.

Golden Eagles are spreading their range from southern Scotland into England. Around 50 Golden Eagles have been translocated across Scotland since 2018 in an attempt to save this species amidst major population decline. In the past 7 years, South of Scotland Golden Eagle Project (SSGEP) have successfully translocated 28 juveniles and 15 sub-adult golden eagles from the Scottish Highlands to the Scottish borders. Satellite tagging has revealed that a number of birds are beginning to venture into Northumberland, the North Pennines, the Lake District and even as far south as Lancashire and Yorkshire, offering hope for the future reintroduction of Golden Eagles into England.

Environment 

Reservoir projects fast-tracked in an attempt to secure England’s water supplies. Two major new reservoirs in East Anglia and south Lincolnshire have been fast-tracked through the planning process as they are now declared as ‘nationally significant.’ As such, the final decisions for these projects will be taken by Environment Secretary Steve Reed, rather than at a local level, with the aim of securing water supplies for future generations. These stores would provide resilience to future droughts in particularly dry areas of the country where water demand is high, and may be completed by 2036 and 2040 respectively. The water industry has welcomed this announcement, but some communities are concerned about increased bills, as well as the potential clearing of homes and farmland to make way for the necessary infrastructure.

Areas of common ground in the Yorkshire Dales are being restored to their ancient glory. A groundbreaking tree-planting programme is uniting farmers and rewilders alike to bring species back to ‘ghost woodlands’. Howgill Fells had been heavily grazed for hundreds of years, but in just over a decade, an extensive rewilding project has planted 300,000 native trees across common land in 64 acres of sheep-free enclosures. Ecologist Mike Douglas recently conducted his first of four annual surveys monitoring birds in the enclosures. His results have revealed the presence of 11 new breeding bird species since his original survey in the early stages of the project in 2016, and numbers continue to increase year on year. 

Policy 

Labour have rejected a proposal to provide every new home with at least one swift brick to help endangered cavity-nesting birds. The proposed amendment to the governments Planning and Infrastructure bill requested that every developer provides a single £35 hollow brick for swifts, house martins, sparrows and starlings in every new build home. This was previously supported when it was tabled on Conversative government legislation in 2023, however the current Labour-dominated committee have now stated they are not convinced it is the right approach. A petition calling for these bricks to become mandatory has now reached 80,000, demonstrating the public’s concern on the matter.

Nature-friendly farming fund to be cut in UK spending review. Labour initially promised £5 billion over two years for the post-Brexit farming fund, which will be honoured until 2026, however in the years following it will be slashed in line with wide-scale budget cuts. This nature-friendly initiative replaced the EU’s Common Agricultural Policy and rewards farmers for stewarding nature, soil, and other public goods, rather than solely for land ownership and cultivation. While DEFRA have stated they are planning a new scheme aimed at smaller farms, many larger-scale ones will miss out on these incentives.

#NoMowMay 2025

a vibrant patch of flowering Red Clover

2025 marks the fifth year that NHBS has participated in Plantlife’s #NoMowMay campaign which encourages people across the UK to put away their lawnmowers and let their grass grow wild throughout the spring, with the aim of providing vital habitats for a wide range of species. As in previous years, we requested that the verges and lawns surrounding the premises be spared from mowing or strimming from late April and all through May to allow more plant species to flower.

We’ve seen good numbers of daisies, buttercups and Germander Speedwell alongside a handful of charming clover species including Red and White Clovers and Black and Spotted Medick. Ribwort Plantain, Common Vetch, Ox-eye Daisy and docks are adding height in places and a handful of common grass species are present and swaying nicely.

Common Spotted Orchid

We do have one beautiful Common Spotted Orchid flowering now as June begins, though sadly, there’s not been returning Bee Orchids this year, for the first time while we’ve been participating in the campaign.

There’s been a fair few bees, wasps, flies and beetles visiting the flowers, though invertebrate activity all round has felt somewhat diminished from previous years. Through May we had scattered sightings of Orange-Tip, Peacock and Tortoiseshell butterflies, and now as June is arriving Meadow Browns have emerged.

#NoMowMay is a fantastic initiative by Plantlife that has highlighted the importance of giving wild plants places to thrive through a crucial stage in their lifecycles and therefore enrich and advance the opportunities for pollinator species, and the wider web of life that depends upon green spaces, including us humans. It’s vital that spaces are left wilder for longer than May, and to encourage this, Plantlife are encouraging the public to let their lawns or grassy areas continue to bloom through June (and again, ideally beyond) with #LetitbloomJune! We’re hopeful that our lawn will be left to flower throughout the summer too.

Outside NHBS at the beginning of June 2025

At NHBS we offer a large variety of books for learning more about habitat maintenance, the importance of species who rely on the restoration and reinvigoration of wilder spaces and many helpful field guides for identifying who’s growing in and visiting your local park or garden!
