Passerellidae
Quite nimble and agile, demonstrated by their ability to hop and manoeuvre effectively through dense vegetation and their quick retreating behaviour when disturbed. Their small size and light weight (14-18g) contributes to their manoeuvrability.
As a small passerine weighing between 12-53g, the Song Sparrow possesses modest strength. While capable of scratching for food and building nests with various materials, their physical power is proportionate to their small size. They can defend territories but aren't known for carrying heavy materials or prey.
Remarkably adaptable birds, Song Sparrows thrive across diverse habitats from sea level to 2,800m elevation, including woodlands, marshes, gardens and urban areas. Their varied diet, ability to learn multiple song variations, and some populations' capacity to drink saltwater demonstrate exceptional adaptability.
Whilst generally peaceful, Song Sparrows show moderate aggression in defending territories and nests. Males actively establish and maintain territories through singing and occasional confrontations, but they're not notably aggressive compared to other songbirds and typically avoid conflict except during breeding season.
Demonstrates good endurance through regular foraging activities and ability to survive in varied conditions. Their capacity to maintain stable territories year-round and forage continuously in their habitat indicates solid stamina, though not exceptional by avian standards.
