HC Deb 03 April 1969 vol 781 c154W
Mr. Burden

asked the Secretary of State for the Home Department what steps are being taken to prosecute those responsible for capturing the wild chaffinches used in a recent experiment at Cambridge University.

Mr. Merlyn Rees

I have no reason to believe that the persons concerned have committed any offence.

Mr. Burden

asked the Secretary of State for the Home Department for how many chaffinches was a licence granted for the recent experiment at Cambridge University in which the birds were deafened in order to ascertain how they learn to sing.

Mr. Merlyn Rees

No restriction as regards numbers was imposed on the certificates under which these experiments were authorised. The research project has now been completed and the relevant certificates are no longer in force.
