Frogs are calling.......



Hearing frogs is easy, but locating one is a rather difficult task, because they are usually well camouflaged into the environment.


 
Unless it is during the mating season when they often emerge from the  water. That is when I found two Gunther’s Frogs (Barking Frogs). You may have guessed from its name that the calls of these frogs sound like a barking dog!
 
 
Unlike birds, frogs often make their calls with their mouth closed. They do so by sucking in and letting out air from the balloon-like vocal sacs in the throat area where the sound is amplified.







This male was calling loudly in order to attract a female close by.
 
 
The female also made calls reciprocal to the male’s which are thought to enhance the reproductivity.








Even during mating, both frogs continued to make calls.











The sound of these constant loud mating calls in the ponds indicates that spring has finally arrived in Hong Kong.

I looooove frogs!
Even getting close enough to takes pictures is not always that easy but with the mating season they are quite caught up with each other!...
That is a great series of pics!

I really like that frog in your sound you announce in the spring. I like them, and their pictures in different situations are great and charming. Yours.
