So as you can see, the croak of frogs is very important to them and the reasons behind them makes a lot of sense. Detailed image of the Larynx showing how frogs produce their call. Actually, this is not true, while it might seem that way, frogs can croak at different times a day depending on various weather conditions.
Frogs and toads are adapted to different water or air temperatures, so if they lay their eggs in water that are too hot or too cold, it will effect their offspring and might even kill them, causing their blood line to stop and quickly disappear.
Each species of frogs can have different sensitivity to temperature, but one example is that of the Spring Peeper Pseudacris crucifer that started to call when the water temperature was as low as 4 degrees Celsius, and stopped when it reached 22 degrees. Another species called Bullfrogs will not even bother until the water temperature reach 16 degrees.
Frogs tend to dry, they spend most of their time in water, so when they need to call for a mate, they step out of the water, and if at the same time there is high dry winds, this could be a problem for them. So there you have it, you now know why frogs croak at night and in general.

Because the aim of the encounter is to breed, male frogs typically call in or near water ponds, dams, streams and wetlands , where eggs are most often laid and tadpoles develop. Some frogs call in the water, some on nearby rocks or on the bank, and others in trees or on the ground nearby.
Different frog species breed in different kinds of water-bodies, so, not surprisingly, different frog species call from different kinds of water-bodies. The Orange-thighed Tree Frog Litoria xathomera typically calls from trees around temporary ponds, and the Common Eastern Froglet Crinia signifera calls in shallow swamps, flooded glassland and puddles. Female frogs even have ears tuned into the specific call of their own species, so that they can locate a male of their own species in a chorus of multiple, noisy males.
Knowing what each frog species sounds is also a great way for us humans to identify our local frogs, without having to disturb them. Once you learn what each local frog species sounds like, you can survey for frogs just by listening! Most frog species are nocturnal and are therefore more active, and vocal, after dusk. So night time is the best time to hear frogs calling.
Given their reliance on water for breeding, it's not suprising that frogs tend to call more after rain. Male frogs croak to attract a potential mating partner. This type of communication is effective because it can reach far and ponds or other waters are often quite large. Frogs croak at night because this is the safest way to let females know that they are available. It is the safest way to go because in this way the frogs can avoid day-time and visual predators.
Most species will only call at night and also will be much more active during the night hours because it is the safe way to go. However, the frog that is calling at daytime has a different strategy. They most likely croak to mark their territory or just a quick call for a mate. Some frogs croak almost only during the day. The poison dart frogs, for example, will croak all day long. Bright warning colors mean absolutely nothing when it is night time and no one can see them.
Some people say that frogs and other animals can predict when there is an upcoming storm and that is why they croak. I am a believer in this story. Now, I am not a scientist but there is some research out there that states that frogs can detect changes in barometric pressure. Now other people say that frogs croak all the time but you just hear them louder just before a storm.
This would be because the sound is reflected and magnified by the low hanging clouds of the storm. The croaking of the frogs will echo more loudly because of that. There are also experts that say that they croak just before it starts to rain to attract a mate. So, how do frogs croak? Frogs croak by moving air over their vocal cords and causing them to vibrate. To amplify this sound they make use of the sack at the bottom of their mouth.
This sack can stretch out like a balloon and a frog can use this to make the sound they make stronger. Amplifying allows for the sound to travel up to 1 mile away. Frogs have vocal cords just like humans do. By moving air over the vocal cords, they start to vibrate and these vibrations then produce a sound. But frogs use more than just their vocal cords when they croak.
