How to take part

Keep a list of the different birds that you see using your garden over the course of a week.

  • You can optionally record the maximum number of each species you see together during the week (e.g. three Blackbirds seen together at one time).
  • You can optionally record other wildlife (mammals, amphibians, reptiles, butterflies, bumblebees and dragonflies).

What to record

Record species that you are confident you can identify correctly; if you can't identify the less common birds in your garden, it's ok to leave them off.

You can choose whether or not to record other wildlife. 

You can record birds that you only hear, as long as you are sure what they are, and that they are in your garden.

You should only record birds and animals actually using the resources in your garden. For example:

  • Birds on your bird feeders, perching in shrubs or nesting on your house.
  • Birds feeding on insects in your garden, e.g. Swallows flying low.
  • Butterflies feeding on your flowers or frogs in your pond.

Do not include birds that are flying past overhead and not using your garden.

It's fine to just record if a species is present, and not include a count. If you choose to include a count, remember that it should be the maximum number of the species that you saw together at any one time (e.g. three Blackbirds seen at the same time). You should not add counts from different times together. If you see two Blue Tits on your bird feeder one day, then four together another day in the same week, this should be recorded as four, as this is the maximum. 

You should not add up counts even if you know different individuals are visiting your garden at different times, for example a male and a female Blackbird. This is because not all species can be differentiated or sexed effectively, so it would inflate the counts for those that can be.

You don’t have to provide bird food, but if you do you should record the food you provide. If you have a pond, please mark 'water' each time.

Where to record

We are interested in records from all gardens, even if you don’t see many birds! Records from a small city garden are just as valuable as those from a large rural garden. 

Decide what part of your garden will be your ‘recording area’; all your lists should be from this area. For most people this will be their whole garden, but if you have a large garden, or it is not all visible from the house, it should be an area you can easily see. 

You will be asked to answer some simple questions about your garden when you first register for the survey. 

When to record

You can spend as much or little time as you like recording for GBW, but please try to spend a consistent amount of time making your weekly lists, so that they are comparable with each other.

Many people will simply record what they see during the course of a week. However, if you spend different amounts of time at home from week to week, you might want to define a set recording period, e.g. while having breakfast each morning, or just at the weekends. The main thing is that your lists should reflect the birds using your garden, not the amount of time you have spent watching them!

If you are able to send in a list every week this would be very valuable data. However, it’s still useful if you are able to send in lists less often, or only occasionally.

You can record with a notebook and pen, or you could keep lists on your phone, or download our printable recording forms.  

How to record

The GBW recording week runs from Sunday to Saturday, so you should start a new list on Sundays. How you note down your records throughout the week is up to you. Many people simply keep a notebook and pen handy, but you could keep lists on your phone or download our recording forms.

You can't enter your data online until the week is finished; you can then choose to enter data straight after the week is finished, or you can save up several lists to enter later.

You can view and edit all your weekly lists on our online recording system; more information on using the online system can be found here.

If you prefer to submit your data on paper recording forms, that is also an option; please speak to the GBW team.

You can find a printable version of these instructions here. If you have any more questions about recording for GBW, please check our Frequently Asked Questions page, or contact us; the GBW team will be happy to help!
