Best Vitamin K-Rich Foods for Backyard Birdss

Ranked by vitamin k content among foods safe for backyard birdss in the Creature Feast catalog.

Spinach per 100g: 483ug Vitamin K1 Spinach is rich in Vitamin K at about 483ug per 100g. Vitamin K is essential for the synthesis of blood clotting factors in birds, which is critical because wild birds frequently sustain minor injuries from territorial disputes, predator encounters, and thorny vegetation. Without adequate Vitamin K, even small wounds could lead to dangerous blood loss.

Parsley per 100g: 1,640ug Vitamin K1 Parsley contains approximately 1,640ug of Vitamin K per 100g, one of the highest concentrations of any food. Even small amounts of finely chopped parsley provide significant Vitamin K for blood clotting factor synthesis. Vitamin K also plays a role in calcium metabolism, helping direct calcium into bone tissue rather than soft tissue.

Broccoli per 100g: 102ug Vitamin K1 Broccoli provides about 102ug of Vitamin K per 100g. The Vitamin K in broccoli supports osteocalcin production, a protein that helps bind calcium into the lightweight yet strong hollow bones that are a defining feature of avian anatomy. Maintaining bone integrity is especially important for birds, whose skeletal system must be both strong enough for flight and light enough not to impede it.

Dandelion greens per 100g: 778ug Vitamin K1 Dandelion greens contain about 778ug of Vitamin K per 100g. Since dandelions grow naturally around gardens and feeding stations, ground-foraging birds like sparrows and robins can access this Vitamin K source through their normal foraging behavior, supporting blood clotting and bone health without any special feeding effort from the garden bird enthusiast.
