1. Screeching:
This high-pitched, piercing screech is the most common sound made by White-bellied sea eagles. It is often used as an alarm call when the bird feels threatened or senses danger to its nest or territory.
2. Whistling:
A series of loud, clear whistles are another vocalisation of the White-bellied sea eagle. They are usually produced during aggressive encounters or territorial disputes between rival eagles.
3. Chuckling:
This is a low, guttural sound that resembles a chuckle or a growl. It is mostly heard from adult eagles when they are with their young or during courtship rituals.
4. Trumpeting:
Trumpeting is a deep, resonant call that sounds like a trumpet blast. It is primarily emitted by male eagles during courtship displays and territorial advertisements.
5. Keening:
A series of mournful, drawn-out wails are known as keening. These calls are often given in response to hearing a distress call or when a nest is threatened.
6. Soft Coos:
White-bellied sea eagles also produce soft coos and murmurs in interactions with their mate or young. These gentle vocalisations are mostly heard within the nest or during intimate moments.
7. Chattering:
Chattering is a series of rapid, high-pitched sounds that resemble the rapid exchange of calls. It is often heard during courtship displays or group interactions.
These diverse sounds serve different functions for White-bellied sea eagles, including:
- Communication with other eagles, especially during courtship, mating, and territorial behaviour.
- Warning and alarming calls to alert other eagles of danger or intruders in their territory.
- Maintaining contact with their young and communicating parenting roles within the nest.
- Expressing aggression and dominance during territorial disputes with rival eagles.
Listening for the vocalisations of White-bellied sea eagles is an exciting and rewarding experience when exploring their natural habitats. Their loud, distinctive calls echo through the forests and coastal areas, providing a window into the lives of these impressive predators.
