These are photos of the European tree frog (Hyla arborea), boomkikker in Dutch.
They live in and near peat bogs in my region of The Netherlands, but they are quite rare and difficult to find, also because they are small, at about 4cm (1.6") in body length for an adult.
Once you have found them, however, they are easier to photograph than other frogs, because they usually are asleep or on their way to a place to sleep, in their favoured bramble bushes, where they feel safe.
It is always nice to have the opportunity to photograph rare species, but these have the added bonus of being very cute.
Well, I think they are.
Thanks for watching!
