English Winter Bird Survey

Time commitment & skill level

The English Winter Bird Survey (EWBS) is a single year national survey, which is primarily aimed at measuring winter bird and Brown Hare populations and their use of food resources in farmland habitats. EWBS uses the network of BTO/JNCC/RSPB Breeding Bird Survey (BBS) survey squares and transects during the winter. All available survey squares can be included, even those with little or no farmland. The survey involves recording all birds seen and heard in randomly selected one-kilometre transect squares, plus some basic habitat recording.

The survey is currently open to those participating in BBS.

Able to identify birds by sight, song and call.

2 to 5 site visits between December and March. The average visit takes approximately an hour and a half to complete.

Fulmar Study

Time commitment & skill level

The Fulmar Study aims to analyse bits of plastic that have been ingested by Fulmars. This species is a good indicator species of the health of our seas. The project so far has shown that 95% of North Sea Fulmars have some plastic in their stomachs.

Anyone who can recognise a Fulmar and finds one dead is able to take part.

Garden Bird Feeding Survey

Time commitment & skill level

The Garden Bird Feeding Survey (GBFS) runs during the winter months and records birds using food or water provided for them in gardens. GBFS participants are recruited from the larger year-round BTO Garden BirdWatch survey. The GBFS has monitored birds in gardens for over 40 years.

Find out more about the Garden Bird Feeding Survey.

Anyone who can identify and record garden birds can take part but participation is limited to members of the BTO Garden
BirdWatch survey.

Weekly from Oct-Mar inclusive. Participants can choose the length of their weekly observation periods.

Nest Box Challenge

Time commitment & skill level

Nest Box Challenge gives you the opportunity to help us learn more about nesting birds in the UK. Anyone with access to a nest box can take part. All you need to do is register the nest box(es) in your garden or local area and record what's inside at regular intervals during the breeding season.Find out more about Nest Box Challenge.

Anyone with access to a nest box can take part.

Check nest boxes once every 4-5 days while birds are nesting.

Reporting a ringed bird

Time commitment & skill level

Using lightweight, individually numbered rings we are able to follow a bird's movements and calculate changes in their chances of survival over time. We are still discovering new facts about migration but the current focus is on monitoring bird populations and understanding why their numbers are changing. Please contribute to these studies by reporting any ringed birds you find using the online reporting form. We will reply with details of when and where 'your' bird was ringed. Find out more about reporting a ringed bird.

Anyone who finds a ringed bird can participate in this survey.

Tawny Owl Calling Survey

Time commitment & skill level

It's easy to take part. All you need to do is listen for Tawny Owls for 20 minutes each week, from 30 September to 31 March. The more weeks that you can listen the better - but you can do as many or as few weeks as you are able. Gaps between weeks don't matter.

You can listen for their familiar 'hooting' and 'kee-wick' calls any time between sunset and midnight. All we ask is that you tell us the date, start time of your survey, an estimate of cloud cover and importantly whether or not you hear an owl.

Anyone who can recog-
nise a calling Tawny Owl.

Listen for 20 minutes, once a week between September 2018 and March 2019

Tawny Owl Point Survey

Time commitment & skill level

The Tawny Owl Point Survey is a simple national structured survey for Tawny Owls starting  Autumn 2018. It builds on previous comparable surveys carried out in 1989 and 2005 to examine national and regional trends in their population and occupancy.

Two visits are required to the centre of a target tetrad less than two weeks apart between mid-August and mid-October.

Anyone who can recog-
nise a calling Tawny Owl.

Make two 20 minute long evening visits.
