The birds received 100 to 1,000 times the concentration that wild birds would encounter in nature. "We couldn't infect the pigeons", Swayne said. "So that's good news."

At New York's Wild Bird Fund, more than half of the 12,000 birds they receive each year are pigeons, some just babies. And a handful, unreleasable into the wild, get adopted. Ghob was one of those ...

Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years.
Flights as long as 1,800 km (1,100 miles) have been recorded by birds in competitive homing pigeon racing; [9] birds bred for this are colloquially called racing homers. Homing pigeons' average flying speed over moderate 965 km (600 miles) distances is around 97 km/h (60 miles per hour) [ 10 ] and speeds of up to 160 km/h (100 miles per hour ...

This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals ...
