Acrocephalidae
The Aquatic Warbler demonstrates remarkable agility, moving nimbly through dense vegetation and climbing vertically up reed stems. Their spectacular song flights, involving ascending high into the air and parachuting down, further showcase their impressive aerial manoeuvrability.
As a small bird weighing only 10-15 grams, the Common Reed-warbler has limited physical strength. However, they possess sufficient strength to weave intricate nests and navigate through reeds, which requires some muscular capability.
The Marsh Warbler shows remarkable adaptability. It can thrive in various habitats with suitable vegetation, not just marshes. Its ability to memorise and mimic calls from both breeding and wintering grounds, along with its complex song repertoire, indicates high cognitive adaptability.
Common Reed-warblers are generally not aggressive birds. They become more territorial during breeding season, with males singing to establish territories, but they don't exhibit notably aggressive behaviour compared to many other bird species.
The Sedge Warbler's endurance is impressive, particularly considering their long-distance migration and ability to increase body weight by up to 70% before migration. Their capacity to sing continuously for up to 240 seconds (4 minutes) also indicates high stamina for their size.
