Earlier this week it was revealed that two young owls in the Rotterdam zoo died from the deadly bird flu strain H5N1. As the first zoo in the world to inoculate all of their birds against the flu, the news came as a surprise.
The owls were born in May, after the last round of shots given to the bird population at the zoo.
A low-pathogenic H7 bird flu strain was discovered at a Dutch farm earlier this month, prompting five countries to ban imports of Dutch poultry.
