Goosander: Diet, Predators, Aggression, and Defensive Behaviors

What do Goosanders eat?

Goosanders mainly feed on fish, making them piscivorous birds. Their diet primarily consists of small to medium-sized fish, such as perch, trout, salmon, and minnows. These birds are well adapted for underwater hunting, possessing a slender and streamlined body that enables them to swim and dive with agility. Using their sharp saw-like bills, Goosanders catch their prey by chasing them underwater, often propelling themselves with their webbed feet.

Do Goosanders have any predators?

While adult Goosanders have fewer natural predators due to their larger size and strong flying abilities, they do face threats during various life stages. Nestlings and eggs are susceptible to predation from mammalian predators like foxes, minks, and raccoons. Additionally, birds of prey, such as eagles, owls, and larger raptors, may prey on young or weaker Goosanders. In aquatic habitats, larger predatory fish like pike or muskellunge can target Goosander chicks or even adult birds when they are in the water.

Are Goosanders aggressive?

Goosanders are generally not considered aggressive birds, especially towards humans or other animals unless they feel threatened or their nest is being approached. During the breeding season, they become more territorial, displaying behaviors like loud calling, head-tossing, or neck-stretching to assert their dominance and defend their nesting areas. While they are not known to attack unprovoked, it is important to respect their space and observe them from a reasonable distance to avoid causing stress or disturbance.

How do Goosanders defend themselves?

To defend themselves, Goosanders employ a combination of defensive behaviors and physical adaptations. When disturbed or feeling threatened, they may resort to flight as their first line of defense and will quickly take off to escape potential danger. Their streamlined body shape and strong wings allow them to fly swiftly and maneuver effectively to evade predators. Additionally, if threatened while in the water, Goosanders can submerge themselves and swim underwater for considerable distances, using their agile swimming abilities to escape predators. This underwater escape is aided by their webbed feet and their ability to hold their breath for extended periods.

Fun Fact: Goosanders are highly social birds and often form small groups or large flocks during the non-breeding season, making them a fabulous sight to behold, especially when in flight as they fly in tight formations.

Fun Fact: During courtship displays, male Goosanders put on an impressive show, stretching their necks upwards and rapidly shaking their heads from side to side while emitting low, repeated calls. This mesmerizing behavior serves to attract the attention of potential mates.
