Although I had been to Costa Rica several times, I photographed these frogs in November, which is considered the rainy season there; I do not of the odds of finding frogs at other times of the year. These frogs seem to stand still at times but in occasion they move constantly making their photographing very difficult. All the time I was with them, they did not appear to be interested in eating but in finding mates. The male will seat in a choice leaf and inflate its throat like a balloon and sings to his heart contents until the girls came around. Some of them took a look at the charmer and keep going; maybe his serenade was not to their liking. I was lucky to get a mating pair, they did not mind me at all; the female will move around carrying the male on her back; this situation took as long as an hour.
Of course not all the frogs were of the same species and I found the one to the right the most appealing.
He was very tenacious and stayed calling for mates for a long time but I did not see if he was successful in attracting mates. Frogs are having a difficult time now a days and it is blamed to the greenhouse effect. They seem to be mostly affected by viruses, fungus and other agents. There is not a real consensus as why this is happening but their disappearance will be a great loss since they feed mostly in insects and they in turn are eaten by birds or humans (in the case of bull frogs.)
Costa Rica is a photographers' paradise with a diversity of ecological niches in the mountains, the Caribbean and Pacific coasts, which are quite different. I found the Pacific most rewarding when it came to photography. Birds are the major attraction for photographers and there several ecological reserves available with nice forests and accommodations. Transportation is a challenge due to the conditions of the roads, particularly in the rainy season, when the roads may get washed away by flash floods. A four wheel drive is highly recommended as well as a GPS since most streets and road are lacking road signs. And beware, you never know when a frog may mistake you for a meal.
