The eaglets have now been both growing strongly, developing pin feathers and spending more time alone on the nest. They are both almost too big to brood, though Lady is working hard to cover them from continual rain today.
SE27 was the first hatched, 26 days ago today. SE28 hatched 2 days later. Delayed incubation of the first egg gave the second a significant chance to catch up. However the first hatched chick will nearly always be bigger and stronger in the first important weeks as a nestling. In some raptor species it is common to see rivalry between the nestlings, with the older chick usually the more dominant. The stronger chick may dominate the food supply, pecking at the weaker to prevent it from eating. In extreme cases it may even kill the weaker. We have seen little sibling rivalry in the first couple of weeks.
Yesterday, at 25 days from hatch, SE27 showed quite aggressive behaviour towards its smaller sibling SE28, pecking it whenever it tried to be fed. SE28’s reaction is to turn away, in a submissive posture. This reduces the aggressive behaviour but prevents it from receiving food. Yesterday SE28 received very little food. Food supplied may have been less, though fish are being brought to the nest.
This sibling rivalry is normal behaviour in many raptors. It may be seen when food is scarce. Neither adult eagle will intervene to prevent this aggression. Again, this is normal behaviour. Maybe a strategy for survival of the fittest nestling?
We are privileged to share the lives of these beautiful eagles. Their behaviour may upset us, but it is their natural behaviour. Mostly this will bring joy and wonder and at times, sadness. If their natural behaviour upsets you, our viewers, it may be better not to watch.
