February is the start of the breeding season for the commonest amphibian in Hong Kong, the Common Asian Toad, Duttaphrynus melanostictus. AP found adults and spawn in Tai Po Kau reserve doing what the book says they do: laying strings of eggs wrapped around vegetation or rocks.
Other frogs and toads in Hong Kong start breeding later in the year, coinciding with the start of the spring rains. Clearly, the trigger to breed is different but what those triggers are in any one species, let along a number living in the same place, has not been sorted out. A fertile search field (excuse the pun) still awaits.
