The mating period of these frogs is during the fall and winter seasons. These frogs call usually during the morning and mid-afternoon hours. [15] Males of this species do not attract females with croaks, instead producing a sharp clicking sound by snapping the hyoid bone in their throats. [16] The clicking sound resembles metallic noises.
Male carrying eggs Tadpole. The common midwife toad (Alytes obstetricans) is a species of midwife frog in the family Alytidae (formerly Discoglossidae). It is found in Belgium, France, Germany, Luxembourg, the Netherlands, Portugal, Spain, Switzerland, and the United Kingdom (although, in the latter, only as an introduction).
