African Bullfrogs make a comeback in Heidelberg
Heidelberg received an exciting natural surprise on December 8 as African Bullfrogs, Africa's largest frog species returned to several parts of town. Residents are urged to keep their distance and drive carefully as these amphibians enter their sensitive breeding season.
Heidelberg residents were met with an exciting natural event on December 8 as African bullfrogs (Pyxicephalus adspersus), Africa’s largest frog species, returned to parts of town.
Authorities and environmental monitors attempted to keep the sightings quiet until the affected areas could be secured, but news travelled quickly through the community.
With bullfrogs now active and moving across certain areas, officials have issued a serious appeal to help protect the frogs during this sensitive breeding period.
The officials urged residents to avoid all areas where bullfrogs have been spotted, stay out of the water, and refrain from approaching or disturbing the animals.
According to environmental observers, male bullfrogs are currently in the phase of establishing dominance, a natural yet highly sensitive part of their breeding behaviour.
Any interference, even from curious onlookers, can disrupt this process and cause unnecessary stress to the animals.
African bullfrogs are notable not only for their return but for their sheer size. Reaching 20 to 30cm, they can grow as large as a dinner plate.
As breeding begins, female bullfrogs will move closer to the males, often crossing roads and intersections.
Motorists are urged to be especially alert along Groenfontein Road and Station Street.
After breeding, the females move up to 2km away, leaving the males behind to guard the eggs and tadpoles. The male bullfrog is known for his extraordinary parental care, defending the young from birds, snakes, and other predators.
When water levels become too low or temperatures rise, the male will dig channels with his hind legs to guide the tadpoles to deeper, cooler, oxygen-rich water. This remarkable behaviour significantly improves the survival of the next generation.
Authorities and local environmental groups urged residents to treat the bullfrogs’ return with respect and caution:
• Do not disturb the frogs under any circumstances.
• Stay away from water sources where they are active.
• Drive carefully near known bullfrog areas.
