Field notes
- Despite their seemingly weak, fluttering flight, Soras are long-distance migrants that can travel from northern Canada to as far south as Peru.
- They possess disproportionately long toes that distribute their weight, allowing them to walk effortlessly across lily pads and floating vegetation.
- Unlike many other rail species that are primarily carnivorous, the Sora's diet consists heavily of seeds from wetland plants like smartweed and wild rice.
- During migration, they can congregate in remarkably high densities, with some marshes supporting dozens of birds per acre.
- They are known to 'pummel' snails against hard surfaces or stalks to break the shells before consuming the soft tissue.
Habitat
Freshwater marshes, wet meadows, and rice fields with dense emergent vegetation such as cattails, sedges, and bulrushes.
Range
Breeds across most of Canada and the northern United States; winters in the southern US, Central America, and northern South America.
