Pterodroma hasitata

  • 62.2 × 46 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 Caribbean islands

Plain white, matt or slightly glossy, as in all petrel and shearwater eggs (we haven't found a description of this species' own egg yet).
