Bee sniffer dog

A Southampton University (UK) postgraduate student is using a sniffer dog to find bumblebee nests. His supervisor says that finding nests has always been a very tricky part of the research, but he thought that perhaps foxes and badgers, bumblebee predators, found their prey by sniffing. It seems that he could be right as Quinn, a springer spaniel is doing a good job. (Report on BBC Countryfile.)
