During the mating process, the female frog produces a foam nest, typically on branches that hang above bodies of water, in order to keep her eggs moist as they develop.

[2] Grey foam-nest tree frogs usually reside in varying habitats, such as savannah, shrubland, forests, pastureland, and urban areas.

[4] Large rainstorms stimulate an increase in breeding from these frogs, because high humidity decreases egg mortality and improves survival across multiple stages of life.

[2] Mating activity of grey foam-nest tree frogs typically occurs at night from October to February in south-eastern Africa's wet summer months.

These frogs choose to mate in arboreal settings, as they create their foam nests in tree branches overhanging bodies of water.

[6] The female grey foam-nest tree frog begins the process of reproduction by producing a thick mucus-like fluid from its cloaca (a cavity at the end of the digestive tract in amphibians).

During this process, the frog uses its hind legs to whip the mucus into elastic froth that will eventually serve as physical protection for the developing eggs.

Grey foam-nest tree frogs that reproduce on land create these nests to minimize drying out, temperature changes, and predation.

[8] Polyandry, an important characteristic of the grey foam nest tree frog, has proven to substantially increase offspring survival.

[5] Polyandry can positively impact fertilization success and offspring production in grey-foam nest tree frogs.

[5] Grey foam-nest tree frogs show remarkable adaptability in their oviposition sites, as they may lay their eggs in a variety of unique habitats.

Grey foam-nest tree frogs that reproduce on land create these nests to minimize drying out, temperature changes, and predation.

Grey foam-nest tree frogs' egg mortality is considered moderate compared to other anuran species.

[4] The grey foam-nest tree frog forms uric acid and excretes it from their body as a nitrogenous end product.

This uric acid excreted can be released in a solid form and does not result in any net water loss for the frog.

This is especially relevant for grey foam-nest tree frogs as they primarily inhabit dry environments, where minimizing water loss is highly important.

[4] The grey foam-nest tree frog forms uric acid and excretes it from their body as a nitrogenous end product.

This is especially suitable for grey foam-nest tree frogs due to the fact that they primarily inhabit dry environments, where minimizing water loss is highly important.

[10] It is known that adults of both sexes of Afrixalus fornasinii prey on grey foam-nest tree frog eggs and tadpoles.
