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
Black-vented shearwater central and southern California during the country's colder months. The black-vented shearwater is thought to feed on mainly small fish. This bird nests in burrows and caves; it is a colonial nester. In the past, this bird had been threatened by feral cats and other predators on its breeding islands, but the problem seems to have been largely eliminated. There is some loss of birds from commercial gill netting, and the species is classified as near threatened by the IUCN mainly due to the uncertain impact on it by the expanding fishing industry.
