Berlin Zoo closes door to visitors over bird flu case

BERLIN (AP) — The Berlin Zoo has shut its doors to visitors due to a case of avian flu among one of its aquatic birds.  The bird — a hamerkop, or a medium-sized wading bird — that had died last week tested positive for the disease following a routine check. The zoo said Friday it will remain closed for the time being as a “precautionary” measure. In the meantime, caretakers are working to quarantine and separate the remaining bird populations. Berlin’s climate ministry said the primary goal is to prevent the spread of avian flu.
