White-bellied sea eagle eggs can typically be left unattended for short periods of time during the incubation period, which lasts around six weeks. However, leaving the eggs unattended for extended periods can be detrimental to their viability.
The Ideal Incubation Period for White Bellied Sea Eagle Eggs
The average incubation period for a white-bellied sea eagle egg is 34 to 36 days. However, the eggs can still hatch after 40 days or even later, although the likelihood decreases as the incubation period extends.
| Incubation Period | Hatch Likelihood |
|---|---|
| 34-36 days | Highest |
| 37-40 days | Moderate |
| Over 40 days | Lowest |
It is important to note that the temperature of the eggs must be carefully regulated during the incubation period. If the eggs are left unattended for too long, they could either cook or chill, depending on the temperature.
Factors Affecting Unattended Periods

The white-bellied sea eagle is generally sedentary and territorial, but it may travel long distances in search of food or if disturbed by humans, especially when nesting. This can lead to the adults leaving the nest unattended for extended periods.
In the case of the Codorus State Park eagles nest, the second egg was left unattended for more than an hour, which raised concerns about its viability. The adults’ behavior in leaving the nest unattended for such a long period suggests that something may not be right with the egg, and it may not hatch.
Importance of Constant Monitoring
The breeding season for white-bellied sea eagles varies according to location, and the species is monogamous, forming permanent pairs that inhabit territories throughout the year. Constant monitoring of the nest and the adults’ behavior is crucial to ensure the eggs’ survival.
If the adults are observed leaving the nest unattended for extended periods, it could be a sign that the eggs are not viable or that there is something wrong with the nest or the adults themselves. In such cases, it is important to consult with wildlife experts or conservation organizations to determine the appropriate course of action.
Conclusion
In summary, white-bellied sea eagle eggs can typically be left unattended for short periods, but extended periods of unattendance can be detrimental to their viability. The temperature of the eggs must be carefully regulated, and the adults’ behavior can provide clues about the eggs’ viability. Constant monitoring of the nest and the adults’ behavior is crucial to ensure the eggs’ survival.
