With Britain experiencing its largest ever outbreak of avian flu, the government ordered this week that all poultry and captive birds must be housed.

The ravens at the Tower of London are said to keep the country together.

A spokeswoman for Historic Royal Palaces, which manages the Tower of London, said that the ravens are isolating in their enclosures.

The spokeswoman said that they are going to enlarge their enclosures to give them more space. The situation will be closely monitored and followed by the government.

The ravens can be seen from a distance. The birds were isolated by The Evening Standard.

Anne Boleyn, the second wife of Henry VIII, was one of the notable figures held in the tower. If there aren't at least six ravens on the grounds, the kingdom and tower will fall. The ravens are usually under the watch of the tower's ravenmaster.

The ravens are the most recognizable birds in Britain, but the danger posed by the bird flu has become a major threat to all birds. According to The Financial Times, Britain has lost 40 percent of its free-range turkeys because of the flu. The experts say there is little risk to humans.

Bird keepers are required to shut their birds indoors. There have been more than 200 cases of bird flu.

The government said this week that it was the most effective way to reduce the risk of disease spreading. If these actions aren't taken, your birds could be killed by the disease.

Britain is not the only country dealing with record-setting bird flu. The European Centre for Disease Prevention and Control said in early October that the epidemic season in the next four years will be the largest on record.

According to the Centers for Disease Control and Prevention, the United States is approaching a record number of bird deaths. The previous record was set in 2015.

Bird keepers have been forced to move vulnerable birds inside due to the outbreak. The experts think the virus will continue through the winter.
