As a member, Garden BirdWatcher, active surveyor or if you register to receive communications via email, then messages you receive may be trackable at an individual level, allowing us to determine, for example, email being opened and links being clicked. This information is generally used to help assess the effectiveness of communications so that we can improve them and may occasionally be used to send relevant further communications in response to your actions (e.g. clicking a particular link) or inactions (e.g. not opening an email). You can unsubscribe from email communications at any time using the unsubscription link contained in each message.

Category 3: Functionality cookies

Only effecting users that have registered to participate in survey recording, these cookies allow the website to remember choices you make (such as your language or the region you are in) and provide enhanced, more personal features. For instance, in the future, may be able to provide you with bird information local to you by storing in a cookie the region in which you are currently located. These cookies can also be used to remember changes you have made to other parts of web pages that are customisable, for instance your choice of alphabetic or systematic order when looking for species information. They may also be used to provide services you have requested such as watching a video or commenting on a blog. The information these cookies collect is only used for the purpose of providing these features and they cannot track your browsing activity on other websites.

Category 4: Cookies not in use by BTO

The BTO does not make use of cookies referred to as ‘Category 4’ in the ICC UK Cookie guide. These may be described as ‘targeting cookies’ or ‘advertising cookies’ - generally used by a third party (usually an advertising network). They may be used to register when adverts have been shown to a user, or monitor when a user clicks on advertising - providing a picture of a unique user’s browsing habits. These are services the BTO does not implement.
