Every winter, I’m reminded how much information can be gathered from something very simple: standing still and watching birds. The RSPB Big Garden Birdwatch is built on that idea. It doesn’t ask for specialist skills or expensive equipment, just attention and consistency. Yet year after year, it delivers one of the clearest snapshots of how garden birds in the UK are really doing.
Thank you for reading this post, don't forget to subscribe!This article takes a practical, clear look at the Big Garden Birdwatch 2026: how it works, why the data matters, what birds are usually recorded, and how gardeners and birdwatchers can take part in a way that is both accurate and meaningful.
What Is the Big Garden Birdwatch?
The Big Garden Birdwatch is an annual nationwide bird survey organised by the Royal Society for the Protection of Birds (RSPB). It takes place over a single weekend in late January and invites people across the UK to count birds for one hour in their garden or a nearby green space.
Unlike many wildlife surveys, this one focuses specifically on common garden birds. That focus is intentional. Gardens, balconies, and small urban green spaces make up a surprisingly large part of the UK’s total habitat. Monitoring what happens in these spaces provides valuable insight into long-term population changes that might otherwise go unnoticed.
The Birdwatch has been running since 1979, which means its dataset now spans more than four decades. Very few wildlife surveys have that level of continuity, especially ones based on public participation.
When Is the Next Big Garden Birdwatch?
Mark your calendar: the 2026 Big Garden Birdwatch runs from Friday 23rd to Sunday 25th January.
One of my favorite things about the Birdwatch is that it’s flexible. You don’t need to get up at dawn if that’s not your style — pick any one-hour window that works for you. Personally, I like late morning: the sun is up, the light is perfect for observing, and birds tend to visit feeders actively after the early morning rush.
Participating is completely free. You don’t need to be an RSPB member, and it’s open to anyone — from families to solo watchers.
Big Garden Birdwatch 2025: Top Recorded Species
The 2025 results confirmed familiar patterns while also highlighting ongoing changes in the UK’s garden bird community. Based on submissions from over 590,000 participants, more than 9.1 million birds were recorded across 80+ species during the survey weekend.
The table below shows the 10 most commonly recorded species in the 2025 Big Garden Birdwatch, ranked by total number of individuals counted nationwide.
Top 10 Garden Birds – Big Garden Birdwatch 2025
| Rank | Species | Birds Counted (2025) | Notes |
|---|---|---|---|
| 1 | House Sparrow | 1,211,260 | Remains the most recorded species for the 22nd consecutive year, despite long-term decline |
| 2 | Blue Tit | 946,698 | Highly adaptable and strongly associated with garden feeders |
| 3 | Woodpigeon | 859,780 | Continues to increase its presence in gardens and urban areas |
| 4 | Starling | 784,741 | Lowest ranking recorded to date; reflects ongoing national decline |
| 5 | Blackbird | 732,472 | Still widespread, but increasingly absent from some urban gardens |
| 6 | Robin | ~700,000+ | Frequently recorded; often benefits from garden feeding |
| 7 | Great Tit | ~650,000+ | Stable presence, common at feeders |
| 8 | Goldfinch | ~600,000+ | A long-term success story linked to seed feeding |
| 9 | Magpie | ~500,000+ | Highly visible and adaptable |
| 10 | Long-tailed Tit | ~450,000+ | Often recorded in winter flocks |
Rounded figures are used for species outside the top five, reflecting aggregated national totals.
What These Numbers Tell Us
Several key points stand out from the 2025 data:
- House Sparrows remain widespread, but their long-term decline means their continued dominance should not be taken for granted.
- Starlings falling to fourth place is one of the most concerning signals, confirming their ongoing population collapse despite being a familiar garden bird.
- Woodpigeons ranking third reflects how adaptable species continue to benefit from urban and suburban environments.
- Goldfinches’ strong position reinforces how supplementary feeding has helped some species recover or expand.
Importantly, these rankings are not simply popularity lists. They represent relative abundance, distribution, and detectability across hundreds of thousands of gardens observed under the same conditions.
Why the 2025 Results Matter in a Bigger Context
On their own, the 2025 numbers provide a clear snapshot of winter garden birdlife. Their real value, however, lies in comparison.
Because the Big Garden Birdwatch has been running since 1979, the 2025 data can be directly compared with decades of earlier results. This allows conservationists to distinguish between:
- short-term fluctuations caused by weather or food availability
- long-term population changes driven by habitat loss, disease, and climate pressures
The continued high level of participation also reinforces the Birdwatch’s role as one of the most reliable large-scale indicators of garden bird trends in the UK.
Why January Is Important
January is not a random choice. Winter is a challenging period for birds, particularly small species. Food availability is limited, vegetation cover is reduced, and energy demands are high.
By counting birds at this time of year, researchers can:
- Assess which species are managing well in winter conditions
- Identify species that may be struggling to find food
- Compare year-to-year changes under similar seasonal pressures
Because the Birdwatch happens at the same time every year, the results are comparable, which is essential for understanding long-term trends rather than short-term fluctuations.
Who Can Take Part?
One of the strengths of the Big Garden Birdwatch is its accessibility.
You can take part if you have:
- A garden
- A balcony
- A courtyard
- Access to a local park or shared green space
You do not need:
- To be an RSPB member
- Advanced bird identification skills
- Specialist equipment
Beginners often worry about “getting it wrong”. In practice, the survey is designed to work with varying levels of experience. Even incomplete or low counts still contribute useful information, particularly when combined with thousands of other observations.
How the Bird Count Works
Choosing Your One Hour
Participants choose any one hour during the Birdwatch weekend. Morning often brings the most activity, especially near feeders, but this is not a rule. Late morning or early afternoon counts are equally valid.
Consistency matters more than timing. Sitting quietly and watching carefully will usually reveal more birds than constantly moving around the garden.
Counting Rules Explained Clearly
The counting method is simple but specific:
- Only count birds that land in your garden or chosen space
- Do not count birds flying overhead
- For each species, record the highest number seen at one time
For example: If three starlings arrive together, then later five arrive together, the correct count is five, not eight.
This method avoids double counting the same individuals and makes the data more reliable at a national scale.
Submitting Your Results
After your hour is complete, results are submitted online via the RSPB website. You’ll be asked to:
- Confirm your location type (garden, park, balcony, etc.)
- Select species from a list
- Enter your counts
If you see no birds, submitting a zero count is still important. Absence data helps identify areas where bird activity may be declining.
What Happens to the Data?
This is where the Birdwatch becomes more than a simple activity.
All submitted results are combined and analysed by conservation scientists. Over time, this allows the RSPB and partner organisations to:
- Track population trends of common species
- Identify long-term declines or recoveries
- Support conservation campaigns with solid evidence
- Inform habitat management and policy discussions
Some of the UK’s most widely cited statistics on garden bird declines come directly from Big Garden Birdwatch data.
Long-Term Trends the Big Garden Birdwatch Has Revealed
Thanks to decades of consistent data, we now know that:
- House Sparrows have declined significantly since the late 1970s
- Starlings, once among the most common garden birds, have shown steep long-term declines
- Greenfinches have been affected by disease and population crashes
- Some species, such as Goldfinches, have increased and adapted well to garden feeding
These trends are not visible in a single year. They only become clear when thousands of small observations are combined over time.
Birds Most Commonly Recorded
Although the exact rankings shift slightly from year to year, a familiar group of species continues to dominate Big Garden Birdwatch results. Their regular appearance is not just a reflection of abundance, but of how well these birds have adapted to living alongside people. At the same time, long-term data shows that even the most familiar garden birds cannot be taken for granted.
House Sparrow (Passer domesticus)
The House Sparrow remains one of the most frequently recorded species, particularly in suburban gardens and areas with mature hedges or nearby buildings. Once overwhelmingly common, its numbers have declined significantly over recent decades, making its continued presence in gardens increasingly meaningful. House Sparrows are rarely seen alone; they tend to arrive in small, noisy groups, moving quickly between feeders, shrubs, and rooflines. Their dependence on suitable nesting sites and reliable food sources makes them especially sensitive to changes in housing design and garden management. Seed feeders offering mixed or sunflower hearts tend to attract them most reliably, particularly when placed close to natural shelter.
Blue Tit (Cyanistes caeruleus)
The Blue Tit is one of the most adaptable species regularly recorded. Comfortable in both rural and urban environments, it readily uses feeders, nest boxes, and even small garden trees. Its bold blue, yellow, and white plumage makes identification easy, even without optical aid. It partly explains its consistent presence in the results. Blue Tits are quick, agile feeders and often appear in short bursts of activity, darting in and out rather than lingering. Their success highlights how adaptable species tend to fare better in changing landscapes. Blue Tits are frequent visitors to hanging feeders and are especially drawn to sunflower hearts and peanuts (in appropriate feeders). Their agility and confidence mean they often appear briefly but repeatedly, so careful observation helps avoid double counting.
Wood Pigeon (Columba palumbus)
The Wood Pigeon is impossible to overlook and continues to feature prominently in the counts. Its large size and confident behaviour allow it to dominate feeding areas, particularly on the ground where it feeds on seeds and plant material. Unlike smaller birds, Wood Pigeons are less dependent on feeders alone and are often seen moving between lawns, fields, and gardens. While their numbers remain strong, their increasing presence in gardens reflects broader changes in land use and food availability.
Blackbird (Turdus merula)
The Blackbird remains a familiar sight in many gardens, but its absence is becoming more noticeable in certain urban areas. Males are easily recognised by their glossy black plumage and bright yellow bill, while females are more subtly marked and often overlooked. Blackbirds spend much of their time foraging on the ground, making them sensitive to hard landscaping and the loss of natural soil areas. Changes in weather patterns, disease, and habitat structure have all influenced their distribution in recent years.
Starling (Sturnus vulgaris)
The Starling is one of the most visible yet most concerning species in the results. Highly social and often arriving in noisy flocks, starlings can give the impression of abundance, even as overall numbers continue to decline sharply. Their acrobatic feeding behaviour and constant vocalisations make them a memorable part of the count, but long-term data shows a significant population drop. Their decline is closely linked to the loss of suitable nesting sites and insect-rich feeding areas. Starlings use both feeders and open ground, favouring suet, mealworms, and mixed feeding areas.
Together, these species form the backbone of Big Garden Birdwatch results. Their familiarity helps participants engage with the survey, but their trends tell a deeper story. Changes in their numbers over time provide some of the clearest insights into how urbanisation, garden management, and environmental pressures continue to shape bird populations across the UK.
Why Gardens Matter More Than We Think
Taken individually, a single garden may seem insignificant. Collectively, gardens form one of the largest areas of green space in the UK.
How gardens are managed has a direct impact on bird survival:
- Year-round feeding supports winter survival
- Native planting provides shelter and insects
- Reduced pesticide use helps insect-feeding species
- Clean water sources are essential in freezing weather
The Birdwatch highlights how everyday decisions made by homeowners and residents influence national bird populations.
How to Make Your Count More Effective
Set Up for Clear, Undisturbed Viewing
The Big Garden Birdwatch is designed to be simple, but a little preparation can make your one-hour count clearer and more reliable. If you use feeders, placing them where you have a clear line of sight from a single viewing spot helps reduce unnecessary movement. Feeders positioned near shrubs or trees often attract more birds, as they offer nearby cover, but overly dense foliage can make identification difficult. The most effective setup usually balances shelter for birds with visibility for the observer.

Binoculars are optional, but they can be helpful, particularly in larger gardens or more open spaces. Even a compact pair can make it easier to distinguish between similar species or identify birds feeding further away. Keeping binoculars within reach is usually enough — there’s no need to use them constantly.

Observe Calmly and Let Activity Build
Remaining still is one of the simplest ways to improve your count. Birds are quick to respond to movement, especially close to windows or doors. Sitting quietly, either indoors or outside, allows birds to return naturally and behave as they normally would. It’s common for gardens to seem quiet at first, particularly in cold winter conditions, but activity often increases once birds sense there is no disturbance.
It also helps to focus on one area at a time rather than scanning constantly between different parts of the garden. Watching too widely can make it easier to miss birds or accidentally count the same individuals more than once. A steady, patient approach usually leads to clearer observations.
Record What You See as You Go
Keeping brief notes during the hour makes the final count more accurate and less confusing. Writing down species as they appear and updating the highest number seen at one time helps avoid double counting, especially when birds arrive in short bursts. There’s no need for detailed notes — a simple list is enough.
Above all, consistency matters more than the total number of birds recorded. The value of the Big Garden Birdwatch comes from thousands of people observing in a similar way, at the same time each year. Calm, careful watching — even if numbers are low — is exactly what makes the results useful.
Common Questions and Misunderstandings
Do I need to know every species?
No. The survey focuses on common birds, and identification guides are provided.
Can children take part?
Yes. Many families and schools participate, and it’s a good way to build observation skills.
Does weather affect results?
Weather does influence bird behaviour, which is why data is collected across many locations and conditions.
Can I count birds in a park?
Yes, as long as you stay in one place for your hour.
Final Thoughts on Big Garden Birdwatch
The strength of the Big Garden Birdwatch lies in its simplicity. One hour. One location. Careful observation. Repeated by hundreds of thousands of people.
I see it as a reminder that meaningful conservation data doesn’t always come from remote reserves or specialist surveys. Sometimes it comes from ordinary gardens, watched quietly, at the same time each year.
If you already enjoy watching birds, the Birdwatch gives that time a wider purpose. And if you’re new to birdwatching, it’s one of the most straightforward ways to start paying attention — and to contribute something genuinely useful in the process.
