Where can I see a crowned treefrog in Costa Rica?

In Caribbean-slope foothill forest, where it breeds in water-filled tree holes and large bromeliads. It is localised and uncommon, so a guide who knows active breeding sites is the difference between finding one and missing it.

When is the best time to see a crowned treefrog?

Why does the crowned treefrog have spines on its head?

Adults have bony crown spines, which give the species its name. They breed in tree holes and bromeliad tanks, where females even lay unfertilised eggs to feed their tadpoles — behaviour that ties the frog to those specific water-filled sites.
