Increasing numbers of ibises in urban parks facilitate contact with animals the ibises wouldn’t normally encounter, like mallard ducks, gulls and other city birds that are disease reservoirs.

Can white ibises get sick from feces?

Can white ibises spread Salmonella bacteria?

“We found that the strains of salmonella bacteria white ibises are infected with are the same ones people get sick from, especially in Florida,” Hernandez says. “Because white ibises fly from urban to natural environments fairly easily, they could move these strains across large distances.”

Why do ibises travel so far for crayfish?

In the breeding season, American white ibises in a colony at Pumpkinseed Island travelled further to forage in freshwater wetlands and catch crayfish, than nearby saltwater areas where fiddler crabs predominated, indicating their benefit was worth the extra energy expended in fetching them for their young.

Why is Salmonella such a big deal for ibises?

The scientists are focusing on salmonella because it causes one of the most significant diarrheal diseases in people and results in mortality in young wading birds such as ibises. “Urban ibises have extremely high levels of stress hormones and weak immune systems compared with other birds,” Navara says.

Why do ibises catch fish instead of crayfish?

It is unclear whether the fish are more easily caught if overcrowded, or whether sheer numbers of fish mean that ibises are catching them instead of crayfish—normally, fish are more agile than crayfish and hence elude the ibis’s bill more easily. Fish are a more energy-rich source of food for the American white ibis.
