These resources have been reviewed and selected by STEM Learning’s team of education specialists for factual accuracy and relevance to teaching STEM subjects in UK schools.


This resource includes data on blackbirds caught and ringed in a single garden in the UK across a period of several years. It includes interesting background information on the migratory habits of these birds, and the characteristics of European and ‘British’ resident birds.

The data, which is a rich source for scientific investigation, includes the age, sex, wing size and weight of these birds. It also includes data and time stamps, and information about the specific ringing scheme.

Many ideas for investigating the data are included in the comprehensive teacher guidance. No guidance on the specific methods to be used are provided, so this resource is recommended for teachers who are confident in data analysis methods. The data manipulation can be carried out using Excel or other appropriate software.
