Semnornis frantzii

  • 35.2 × 25.5 mm (estimated)
  • Its colour follows its family (the eggs of all its relatives are alike); we haven't found a description of this species' own egg yet. Speculative: we haven't found documented measurements of this egg yet, so we estimated its size from related birds.
Breeds in Costa Rica, Panama

Plain white, as in all toucan-barbet eggs (we haven't found a description of this species' own egg yet).
