Cynanthus doubledayi

  • 12.6 × 8.5 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 Mexico

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