Big Garden Birdwatch 2021

Once again, the RSPB's Big Garden Birdwatch is upon us! This is an excellent opportunity to take some time out of your day to watch the wildlife visiting your garden and to provide valuable data in the country's largest citizen science project! It's also a great way to watch the wildlife visiting your garden from the comfort of your own home.

But what is the purpose of this bird count and what do I need to do to get involved?

How do I Take Part in The Big Garden Birdwatch?

Big Garden Birdwatch has been an annual event for 42 years and it is now the world’s largest garden wildlife survey. It allows the RSPB to gather huge amounts of data on a huge scale up-and-down the United Kingdom to see how our garden wildlife is doing. All you need to do is to spend an hour at your window – or if you don't have a garden – your local park and make note of what types of birds you see during that time. You just need to record the most you see of any type of species you see at any one time. Don't count up the total consecutive birds you see, otherwise, it is likely that you'll be double-counting birds as they tend to visit the area for a second or third time.

This is for everyone – from those with the tiniest of urban gardens or balconies to those with the largest of estates. The more diverse the data, the better! Perhaps you are only visited by the odd wood pigeon or maybe you have a multitude of winged visitors. Regardless, all this information is useful to the RSPB.

This year the birdwatch is happening on 29, 30 and 31 January. All you need to do is spare an hour during this time to see what is happening outside. This is made even easier this year thanks to the COVID-19 lockdown!

All you need to do after your hour is to submit your results to the RSPB online, which you need to do before 19 February. Find out more about how to take part on the RSPB website.

How does the Big Garden Birdwatch Work?

Looking at the bigger picture allows the RSPB to analyse how our wildlife is faring in these tumultuous times. We can see long-term trends of declines or increases in bird species. With the threat of climate change, pollution and habitat destruction this survey has never been so important!

Half a million people are involved yearly with this birdwatch, so it is an excellent opportunity to have an in-depth insight into how garden birds are faring across the UK. It enables the RSPB to calculate the overall trend of species over time to see which species are under threat and need help in these ecologically turbulent times.

After you have submitted your results, the number crunching begins! First, all the duplicates, anomalies and errors are removed in the data to ensure that it is scientifically valid. Then the data can be sorted in various ways including by geographical area. From this, populations of different species can be compared. An average number can be calculated based on the abundance of each species. This is set in context against previous years' data to find out any long-term trends.

Between 2007 and 2017 the biggest decrease in a species in the UK was the Greenfinch, which suffered a 66% decline. However, it has been a good period for the tiny Wren, which in this same period has seen a population increase of an impressive 87%!

Why do the Birdwatch in January?

There are a couple of advantages to hosting the birdwatch in January. As it is winter, birdwatching is much easier as leaf cover is at its lowest. This provides fewer areas where birds can hide from our view and therefore it is simpler to spot birds landing in trees or bushes. Furthermore, because food is scarce birds are on the move more to find their next nutritious meal. We can attract them into our garden with a readily available supply of food… which brings us on to the next question…

How can I attract birds into my garden?

Funny you should ask! We have articles on the Dos and Don’ts of Feeding Birds and What We Should Be Feeding Birds on the matter.

The key things to remember are to leave out a variety of bird foods and a supply of fresh water.

Ensure that wherever the bird food is place, whether in a hanging feeder, ground feeder or elsewhere, that it is a quiet place for the birds that is safe from predators and sheltered from the winds. Don’t forget to leave out some fresh water for the birds, or even better, have a small pond that can attract a variety of wildlife.

It is important to ensure bird feeders, tables and baths are regularly cleaned to stop a build-up of germs that can spread diseases among garden birds.

You can even use one of our bird feeder camera kits to get a great close up view of the birds visiting your feeders.

What kinds of Birds Can you Expect to See?

If this is something you have not done before then there are a variety of common garden birds to be on the look out for! These were the top ten most seen species last year in the 2020 count:

1. House sparrow
2. Starling
3. Blue tit
4. Woodpigeon
5. Blackbird
6. Goldfinch
7. Great tit
8. Robin
9. Long-tailed tit
10. Magpie

However, it always pays to keep your eyes peeled for some unusual visitors! At this time of year, we are joined by a whole host of winter migrants who are escaping the harsher winters in regions such as Scandinavia. You never know what may visit your garden so it is always worth being ready to spot something you may not expect.

UPDATE: here were our results from this year in the park next to Green Feathers HQ:
