If you find yourself passing through La Coruña airport in northern Spain any-time, make sure you have a look at the frogs. This small airport is located in the suburbs of La Coruña – also called A Coruña in Spaanish – and is one of a number of gateways into the province of Galicia. A far cry from the hustle and bustle of Heathrow airport – where flights on the airline Vueling depart from – it is relaxed and uncrowded, with a great restaurant. They even serve you a delicious soup from a steaming hot cauldron at your table. Imagine that at Heathrow!

It’s always fun landing at this airport, which is located on a hill about 7 km from the city centre. But what I have come to appreciate as I have passed through this little airport over the years, is that it is a really good place to see Perez’s frog (Pelophylax perezi), also known as Iberian water frog, Iberian green frog, or Coruna frog. I’m not joking! There is a series of ponds at the at the northern end of the airport, just by the road leading out of the airport, and close to the car park. It is easy to find it as there is an example of the traditional Galician stone gain store (or horreo) besides the ponds.

The ponds themselves are covered in water lilies on which the frogs can be seen resting, if you approach carefully. More likely you will hear plop, plop, plop as all the frogs hear your footsteps and jump into the safety of the water!

This frog species is not endangered (although amphibians are vulnerable everywhere), as is widely distributed and common across the whole of the Iberian Peninsula and is found in southern France, and elsewhere where it has been introduced, like Madeira, the Balearic and Canary Islands.

They are highly variable in colour and patterning, and look a lot like the Marsh frog (Pelophylax ridibunda) which is what I thought they were when I first came across them (1). Confusingly, they also hybridise with each other to form a type of hybrid frog!

So whilst not being unusual, you might not come across a better place to see them whist visiting Spain or Portugal, and it is a good way of whiling away some time waiting for a flight. They are particularly vocal and lively, jumping around and inflating their vocal sacs, during the breeding season (Spring) (1).
