Kiwi eggs are remarkably large, averaging around 440 grams, which is approximately 20% of the average weight of an adult female Northland brown kiwi.
This significant size makes kiwi eggs particularly noteworthy in the bird world. A substantial portion of the egg, about 60% (250 grams), is yolk. This high yolk content makes them one of the richest eggs among birds.
Here's a summary of the key characteristics:
- Average Weight: ~440 grams
- Percentage of Adult Female Weight: ~20%
- Yolk Percentage: ~60% (250 grams)
The extraordinary size and yolk richness of kiwi eggs are adaptations that contribute to the survival of kiwi chicks, providing them with ample nutrients for development. The large yolk allows the chicks to hatch at a more advanced stage, enabling them to be more independent from birth.
