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
Calonectris the Early Pliocene and "Calonectris wingatei" from the Middle Pleistocene, have also been described from fossils. "Calonectris kurodai", another fossil from the Middle Miocene Calvert Formation of Chesapeake Bay is named after the Japanese ornithologist Nagahisa Kuroda. Calonectris Calonectris is a genus of seabirds. The genus name comes from Ancient Greek "kalos", "good" and "nectris", "swimmer". The genus comprises three large shearwaters. There are two other shearwater genera. "Puffinus", which comprises about twenty small to medium-sized shearwaters, and "Procellaria "with another four large species. The latter are usually named as "petrels", although they are thought to be more closely related
