Marsh Frog

Description:

The Marsh Frog is the largest water frog native to Europe, recognized for its distinctive green to brownish color and the dark spots that often decorate its back and legs. They grow to some 12-13 cm in length, and are rather stocky. They are known for their powerful legs, enabling them to make significant leaps, and they are excellent swimmers. One of the most notable characteristics of the Marsh Frog is its loud and deep croaking, especially prominent during the breeding season when males call to attract females. The sound is not only a call for mates but also serves to establish territories among competing males. Marsh Frogs are opportunistic feeders, preying on a variety of invertebrates, such as insects, and occasionally on smaller amphibians and fish. Their diet helps control pest populations, underscoring their ecological importance. The breeding season for Marsh Frogs is in spring and early summer. Females lay thousands of eggs in water, which hatch into tadpoles and undergo metamorphosis, transforming into adult frogs. This species plays a crucial role in wetland ecosystems, serving as both predator and prey in their aquatic environments, and their presence is often a good indicator of the health of wetland habitats.

Habitat:

These amphibians are predominantly aquatic and are found in a wide range of wetland habitats, from large lakes and rivers to marshes and man-made water bodies like ditches and reservoirs. Seen in wetlands of Hortobágy National Park, just after visiting beavers. These wetlands are part of the network of shallow lakes, marshes, and sodic lakes (alkaline lakes) that dot the landscape of the park, offering a rare glimpse into the diverse aquatic ecosystems of the Eurasian steppe. Formed by the backwaters of the Tisza River, these wetlands are crucial for the survival of several species of migratory and resident birds. The area serves as a vital stopover for tens of thousands of cranes, geese, and other migratory birds traveling along the East Atlantic and the Black Sea-Mediterranean flyways each year, making it a spectacular site for birdwatching, especially during migration seasons. The biodiversity of Hortobágy's wetlands is notable, with a variety of waterfowl, waders, and other bird species finding refuge and breeding grounds here. This includes globally threatened species such as the Great Bustard and the Aquatic Warbler. The wetlands also support a range of other wildlife, including amphibians, fish, and aquatic invertebrates, which contribute to the ecological balance and richness of the area.

Notes:

Hortobágy National Park, the first national park in Hungary, is an emblem of the country's natural beauty and cultural heritage. Sprawling across the eastern part of Hungary, it is the largest protected area in the country and part of the Great Hungarian Plain. This UNESCO World Heritage site is famed for its vast grasslands, traditional pastoral culture, and diverse wildlife, including unique bird species. Hortobágy serves as a crucial habitat for numerous bird species, making it a haven for birdwatchers and nature enthusiasts. Its landscape, characterized by open pastures, wetlands, and the traditional lifestyle of herdsmen, reflects centuries of human and natural history intertwined.
