Those included the great bustard ("Otis tarda"), Montagu's harrier ("Circus pygargus"), ravens, buzzards ("Buteo" sp.), redpolls, wrynecks ("Jynx"), which are small woodpeckers that specialise in feeding on ants. "The vast warrens of the 'Breck', the woods and water-meadows of the valley of the Little Ouse, and the neighbouring Fenland made an ideal training-ground for a naturalist". This enthusiasm Newton shared with his younger brother Edward: the two carried out bird observation when they were together and corresponded when they were apart. In 1846 Newton went to a tutor in Biggleswade for a few months,
Edwardsiella tarda along with maintaining suitable sanitation of water. Other stress factors include drastic changes in temperature, pH, and dissolved oxygen levels in the water. In order to manage properly for edwardsiellosis water must be checked constantly in order to keep fish stocks completely free of pathogens. Some of the most recent research done on "Edwardsiella tarda" was performed by Griffin et al. (2013) to assess what the literature refers to as "the intra-specific variability of "E. tarda" isolates from 4 different fish species in the eastern United States." These intra-specific variations that they were looking for occur in other parts of
