The Honolulu Zoo is asking residents to remain on the lookout for a bird that went missing in March, after vandals cut holes in cages.
Two other birds were found shortly after going missing.
Tips on the third bird — a tawny frogmouth — continue to come in, but zoo staff said all the tips so far have turned out be misidentifications.
Zoo staff remain hopeful the tawny frogmouth is alive, however.
The bird is native to Australia and was hand-fed and docile. It has a large head with brownish-gray feathers and a frog-like mouth.
The three exotic birds got out after vandals cut holes in 24 bird cages at the zoo.
