Curators say a Norwegian exhibition on homosexuality among animals has been well received, despite initial indications of strong opposition.
The Oslo Natural History Museum opened the show last week and says it has been well attended, not least by families.
Organisers reported early criticism of the project, and being told by one opponent they would "burn in hell".
But there has been strong interest in an aspect of animal behaviour the museum says is quite common.
It says homosexuality has been observed among 1,500 species, and that in 500 of those it is well documented.
Animals can be queer as well - 10% or Penguins in fact. One could expect it of Flamingos, but Penguins?
