They drilled holes into the bottom of a lake so that the Avocet’s could access wildlife below the frozen surface of the lake and in the mud at the bottom.
Viewers were left in hysterics when the pair pulled the valve out of the water and tried to empty the mud out of it.
Dr Ross told Martin that it should easily fall out after some “vigorous shaking”, with the host cheekily replying: “It’s coming, it’s coming.”

The pair had viewers in hysterics as they tried to empty mud out of a valve
When Martin tried to drill holes into the bottom of the lake himself however, he struggled to eject the mud from the valve that they used.
Dr Ross asked: “Can you feel it coming?” to which he sighed: “No, I can’t feel it coming.” As he shook the piece of equipment, she encouraged: “Try it faster then.”
Many were quick to comment on Martin’s attempts with some joking that the innuendos had begun early this year.
Taking to social media, one viewer tweeted: “Vigorous shaking, it's coming, it's coming, squelch – ooh Martin – how smutty! #Winterwatch @BBCWinterwatch @BBCSpringwatch.”
While another added: “The innuendo on #Winterwatch is like watching a particularly saucy #GBBO.”
