Streptoprocne phelpsi

  • 27.8 × 18.3 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 Brazil, Guyana, Venezuela

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