Conservationists are calling for something to be done about the impact of annual 'Crate Day' on the endangered black-fronted terns in Canterbury.
For those not familiar with Crate Day, it's is an unofficial celebration on the first Saturday of December where those taking part challenge themselves to drink a crate of beer before midnight.
Peter Langlands is from the black-fronted tern protection group, he explains the problems to Jesse.
