There’s a moment in April that I look forward to all year. It’s hard to pinpoint exactly when it happens, but one day you go outside, and the world is suddenly, unmistakably, fully green. Not the tentative green of March. Proper green. Layers of it. And the air smells different. Everything is loud with birds. And you think: oh. There it is.
April is intoxicating. It’s also, for a nature journalist, both the most rewarding and the most demanding month of the year. So much is happening so fast that it genuinely tests your ability to keep up. But that’s also what makes it so worth the effort.
This month I want to talk about migrants, about the explosion of life that April brings, and about why the records you’re building right now matter in ways that go well beyond your own enjoyment.
The Migrants Are Coming
If there’s one thing that defines April for me, it’s the arrival of migrant birds. These are creatures that have spent the winter in Africa or Central and South America and are now making their way back to breed in the northern hemisphere. The distances involved are almost incomprehensible. And yet, year after year, they come back. Often to the exact same field, the same wood, sometimes the same nest.
In the UK, April brings swallows, house martins, willow warblers, blackcaps, and the cuckoo. The first cuckoo call of the year is one of those sounds that stops you in your tracks. In North America, warblers are the big story. Dozens of species move through in April, and keen birdwatchers plan whole trips around the peak migration windows.
The arrival dates of these birds are one of the most important things you can record in your journal. Not because your notebook needs to be a scientific document, but because these dates are shifting. Spring is arriving earlier in many parts of the world. Migrants that evolved to arrive when caterpillars were peaking are now sometimes arriving too late. Long-term citizen records are genuinely helping scientists understand this.
The British Trust for Ornithology has great information about migration research in the UK. For North America, the Cornell Lab of Ornithology’s eBird is one of the most powerful citizen science tools in existence. You can log your sightings and contribute to a global database. It’s free, and it’s extraordinary.
Bluebells and the Ancient Woodland Question
In the UK, late April brings one of the most spectacular wildflower displays in the world. Bluebells. A good bluebell wood in full flower is genuinely breathtaking. The smell alone is worth travelling for.
But bluebells are also an indicator species. Ancient woodland, meaning woodland that has existed continuously for at least 400 years, tends to be where you find the best bluebell displays. These woodlands are irreplaceable habitats that took centuries to develop, and they’re under ongoing pressure from development and non-native species. If you find a good bluebell wood near you, it’s worth knowing what you’re looking at.
The Ancient Tree Forum and the Woodland Trust’s Ancient Woodland Inventory can help UK readers identify ancient woodland near them. For North American readers, old-growth forests play a similar ecological role, and the Old-Growth Forest Network has a map of protected old-growth sites across the US.
While you’re in any woodland this month, look down as well as up. Wood anemones, wild garlic, and early purple orchids are all April flowers in UK woodlands. In North America, trilliums, bloodroot, and jack-in-the-pulpit are blooming in eastern woodlands right now.
The Dawn Chorus at Its Peak
We talked about the dawn chorus building in March. By April, it’s at its absolute peak. This is partly because resident birds are in full territorial song, and partly because migrants are arriving and adding their voices to the mix.
The first Sunday in May is International Dawn Chorus Day, but honestly, April is when it’s most intense. Try to get outside at least once before sunrise this month. You don’t need to go far. A garden, a park, an open window facing trees. The experience of standing in the dark and hearing the world fill with sound as the light grows is one of those things that’s hard to describe adequately. You just have to do it.
For your journal, try writing a dawn chorus entry in real time. Note what you hear first. Note how the sound builds. Write down the exact time the light changes. It doesn’t need to be long. Even a page of notes written outside in the early morning has a quality to it that you can’t replicate later at a desk.
The RSPB has a dawn chorus guide to help you identify what you’re hearing. The Merlin Bird ID app from the Cornell Lab is brilliant for both UK and North American readers. You can hold your phone up to the dawn chorus, and it will identify species in real time from the sound. I find it completely addictive.
Insects, Finally
April is when the insect world really gets going. After months of very little, suddenly there are bees everywhere. Butterflies are out on sunny days. Hoverflies hover. And if you look closely at flowers, leaves, and soil, there’s an enormous amount happening.
Orange tip butterflies appear in the UK in April, one of the most elegant signs of spring. In North America, spring azures, cabbage whites, and various swallowtails start flying, depending on your region.
Bumblebee queens are now busy establishing new nests. If you see a large bumblebee moving slowly along a bank or wall, close to the ground, she’s probably prospecting for a nest site. This is worth noting in your journal with a date. The Bumblebee Conservation Trust has excellent identification resources for UK readers. For North America, Bumble Bee Watch is a citizen science project where you can submit sightings and help track populations.
One prompt I’d suggest for April is simply sitting near a flowering tree or shrub for fifteen minutes and counting what visits it. You might be surprised how many different species use a single cherry tree or patch of dandelions in a short time.
Why Your Records Matter More Than You Might Think
I want to come back to something I touched on in the February post, because April feels like a good moment to sit with it properly.
The records you’re keeping, even casual ones, are part of something bigger. Phenology, the study of seasonal timing, relies heavily on observations made by ordinary people paying attention to the world around them. When scientists want to know whether spring is arriving earlier than it used to, they look at records like yours. First bluebell sighting. The first swallow. First brimstone butterfly and the first frogspawn.
Climate change is affecting these timings in complex ways. Some species are shifting earlier. Others aren’t shifting at all, which causes mismatches between, say, caterpillar emergence and the arrival of the birds that depend on them. Long-term records, even informal ones, are genuinely valuable data.
So keep dating your entries. Keep noting locations. If you see something for the first time this year, write it down with as much detail as you can. You don’t need to submit it anywhere for it to matter, though if you want to, iNaturalist and eBird are both excellent platforms.
Your journal is a small but real contribution to human understanding of the natural world. I find that a genuinely motivating thought.
April Journalling Prompts
One is enough. Take your time with it.
- Note the first migrant bird you hear or see this April. Where were you? What were you doing? Write the date and describe the moment.
- Find a flowering tree and spend fifteen minutes counting every type of insect that visits it. What surprises you?
- If you can get to a bluebell wood or any spring wildflower display, write about the experience of it. Not just what you see, but what it feels like and smells like.
- Set an alarm and go outside before sunrise one morning. Write your journal entry in real time, in the dark, as the dawn chorus builds around you.
- Track one migrant or seasonal species across the whole month. Note every sighting with date, time, and behaviour. What patterns do you start to see?
- Look at something very small this month. A single flower. A patch of bark. A handful of soil. Write about what you find there.
A Thought for the End of April
April can make you feel almost frantic with the desire to see everything before it’s gone. The blossom lasts a week. The bluebells peak and fade. The first flush of green darkens into something more solid.
But that’s the nature of it. And it’s exactly why the journal matters. You can’t hold onto April. But you can write it down, and next year, when the swallows come back, you’ll know the exact date they arrived last time. You’ll have something to compare it to. You’ll be building a relationship with the year that deepens over time.
That, more than anything, is what this practice is about.
Next month: May, the full choir, and the art of listening as well as looking.
