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
Persian shearwater off Oman and Socotra, Yemen, while "P. p. temptator" has been estimated to number fewer than 500 pairs on Moheli Island in the Comoros (reviewed by Brooke 2004). It is thought likely that more breeding colonies lie undiscovered elsewhere in the northern Indian Ocean (Onley and Scofield 2007), thus the total population probably includes more than 10,000 mature individuals. The population trend is believed to be downwards. Persian shearwater The Persian shearwater ("Puffinus persicus") is a seabird in the family Procellariidae formerly lumped in with Audubon's shearwater ("Puffinus lherminieri"). There are two listed subspecies of the Persian shearwater: After breeding,
