  • wings have the largest surface area (measured in square centimeters) of any extant bird (ref: Wiki)
  • It sometimes takes a condor one week to hatch from an egg; Condors do not have talons like eagles or hawks; their nails are more like toenails (ref: ventanaws)


  • Males are assumed to differ from females by {p_Am} only
  • The guess for Wwx is based on the remark that the size at fletching is almost the same as that of the adults (Wiki)
