The Cardiff Blackbird Project was established in April 2012 to examine the ecology, behaviour and demography of urban birds using Blackbirds as a model.
The Blackbird has many traits that make it ideal as a model species. It is common, making for large data sets. It is a relatively large species, meaning it is easy to observe. Blackbirds are also widespread, which allows comparison between populations in different habitats and geographical scales.
The project is based around developing a long-term monitoring programme, contributing to the Retrapping Adults for Survival scheme, on which a number of more detailed research projects examining Blackbird ecology in a suburban environment will be based. Currently the study site for the project is the northern part of Pontcanna Fields, in the area which includes the allotments and Cardiff Riding School.
The success of these projects relies on having a large population of individually marked birds that can be followed throughout the year. Unique plastic colour-rings are fitted so that individuals can be recognised through binoculars or a telescope, avoiding the need to capture birds multiple times. The colour-rings in use are yellow with black letters and are placed on the left leg. A standard BTO metal ring is on the right leg.
If you see a colour-ringed Blackbird, the team would love to hear about it, by logging your records online, or by contacting:
