Best Vitamin B1 (Thiamine)-Rich Foods for Backyard Birdss

Ranked by vitamin b1 (thiamine) content among foods safe for backyard birdss in the Creature Feast catalog.

Sunflower Seeds per 100g: 1.5mg thiamine Sunflower seeds contain about 1.5mg of thiamine per 100g, making them the best feeder source of Vitamin B1. Thiamine is essential for carbohydrate metabolism in the avian nervous system, and its deficiency causes the neurological condition known as star-gazing (opisthotonus) in birds. Adequate thiamine from seeds supports the rapid neural processing that birds need for flight coordination and predator detection.

Oats per 100g: 0.76mg thiamine Oats provide about 0.76mg of thiamine per 100g. Thiamine supports the enzyme pyruvate dehydrogenase, which is critical for converting glucose into usable energy in avian brain and nerve tissue. Ground-feeding birds that regularly consume oats maintain thiamine levels that support their complex spatial memory for food caching and territory navigation.

Peas per 100g: 0.27mg thiamine Peas contain about 0.27mg of thiamine per 100g. While lower than seeds, the thiamine in peas complements seed-based intake and is readily bioavailable from the soft legume matrix. Thiamine is water-soluble and not stored in large amounts, so regular dietary intake from diverse sources helps birds maintain consistent levels.

Pumpkin seeds per 100g: 0.27mg thiamine Pumpkin seeds provide about 0.27mg of thiamine per 100g, adding to the B-vitamin pool from seed-based feeder foods. Every seed species offers a slightly different B-vitamin profile, which is why offering a diverse seed mix at your feeder produces better nutritional outcomes for visiting birds than a single seed type alone.
