Purple Swamphen eggYour model is disabled. For more details go to Edit properties3D Model
This is one of the many Australian native bird eggs that my father (Henry George Landenberger) collected as a youngster. I first identified it as a Pied Butcherbird egg, however it is far too large for that (50×34 mm). The size and pattern do match that of the Purple Swamphen (Porphyrio porphyrio). None of the dozens of eggs in the collection are labelled. Most would have been collected in the early 1930s.
Note the egg has been carefully pierced at both ends in order to drain the contents so the shell could be preserved.
