Project Blackbird

Following Paulo's visit the other week and his anecdotal observations on the biometrics of Blackbirds, we have started some data collection to compare wintering Blackbirds in SW Lancs and the Mondego Valley of Portugal.

Measuring the beak.

Throughout the year, we will take measurements of the beak and tarsus of all new and retrap Blackbirds that we catch.

Measuring the tarsus.

If you are interested in helping collect some biometrics, get in touch!

  1. If you need a much wider sample then we could put something out more generally on the Forum or in RB?????
