The march of the midwife toads

16 comments:
The midwife toads (alytes obstetricans) are on the move. They were spotted carrying their eggs, navigating the limestone rockery, trailing plants and inquisitive cats. Here in Spain they are currently listed as 'Near Threatened' on the ICUN Red-list (International Union for Conservation of Nature).


We are lucky that the midwife toad is plentiful here at La Pasera, the rockery is a perfect habitat for them as there are many moist crevices where they can hide from the heat of the day. Most of the year we can hear them sing out once the afternoon sun starts to set. Their high pitched whistle-like sound: poo...poo...poo is repeated every one or two seconds and other toads will join in, signalling their presence.


If you are unfamiliar with this toad it may come as a surprise to learn that it is the male of the species that carries the eggs; up to 170 eggs at a time, sometimes originating from different females. They have peculiar mating habits with the female and male engaged in a mating ritual, the male inserting a toe into the females cloacae thereby enabling the release of eggs which he then sticks his legs through, sprays them with urine and sperm and carries them for 3-6 weeks until he finds a safe spot to release the eggs.


We have several water sources in the garden but the one the midwife toads prefer is a small half barrel filled with water, plants and a rock. It is permanently teaming with tadpoles thereby ensuring the next generations of this wonderful creature.



The midwife toad is small, 4-6 cm in length with the males being slightly smaller than the females. They live approximately 5 years if not consumed by their natural predator, the viper or large birds. Their diet is mainly spiders and beetles with a few flies and worms when available.
