Harle explained the reasoning behind the naming of the birds.
She said: “We wanted to name the birds using a play on the name rhea, hence we came up with Chris who was named after the late musician.
“While Silvia was named after the Roman Goddess, Rhea Silvia, the mother of Romulus and Remus.”
Harle said they ideally would want Silvia’s soulmate to move in with him, as travelling to another sanctuary would make Silvia nervous.
She says rheas are native to South America and can live between 10 to 15 years in the wild, and 15 years or more in captivity.
“We hope this Valentine’s Day will be Silvia’s year. He had always been with his brother, and he has been on his own since Chris died.”
