Pat Nuttall laboratory reagent, a result that was published in "Nature" in 1977. She then worked with ornithologist Chris Perrins trying to identify the virus responsible for puffinosis, a disease that affects the Manx shearwater ("Puffinus puffinus") sea bird. During this research, Nuttall visited sea-bird colonies and became interested in ticks, arthropods that often infest sea birds as well as other vertebrates, and can act as vectors for disease. In the early 1980s, Nuttall started to study viruses transmitted by ticks, initially focusing on orbiviruses, nairoviruses and thogotoviruses. While performing experiments designed to explore whether "Thogoto virus", an influenza-like virus, can be
Hutton's shearwater a white underbelly and brown collar, dark borders to the underwing, dark grey bill, and pinkish dark-webbed feet; it can be distinguished from fluttering shearwater by its dark grey "armpits". At a breeding colony it has a loud cackling call. Hutton's shearwater feeds in the open ocean largely on small fish and krill, diving up to 20 m. "Puffinus huttoni" have long bills, which are adapted to catch prey more or less underwater by plunging from a few meters above the surface or by paddling slowly forwards searching with their head submerged, then diving using partly opened wings for propulsion.
