What do the U.S. health secretary, Robert F. Kennedy Jr., the celebrity physician Mehmet Oz and some Canadian animal lovers have in common?

They all want to save a flock of 400 ostriches on a British Columbia farm.

But there’s a catch. The birds were in contact with a deadly virus: the avian flu.

Canada ordered the birds to be culled after avian flu spread through Universal Ostrich Farms in Edgewood, British Columbia, a town in the province’s interior, north of Washington State.

The plight of the wobble — a term sometimes used to describe a group of ostriches — has divided Canadians, but the birds have won allies across the border, namely top officials in the Trump administration.

Mr. Kennedy last week urged the Canadian authorities not to kill the ostriches but to do further testing to try to better understand the virus.

“We believe significant scientific knowledge may be garnered from following the ostriches in a controlled environment,” Mr. Kennedy said in a letter to the head of the Canadian Food Inspection Agency, which ordered the culling.
