Project Description

Update: The 2025 spring survey season began on 13 April and is now live. If you are not an existing Blackbirds in Gardens volunteer, and you would like to join the project, you can sign up now.

Time, skill and support

As much as you like, but a minimum of 15 minutes per week is recommended.

You need to be able to identify Blackbirds by sight, including reliably separating adult males, adult females and juveniles (guidance provided).

A simple identification guide to Blackbirds of both ages and sexes, along with some confusion species, is provided within the survey data entry web app.
