Taiga Bean Goose Life Cycle: Nest Building To Fledging (and everything in between)
Arriving as late as November and often departing in February, the Taiga Bean Goose (Anser fabalis) makes its way to the UK in winter.
These geese primarily spend their winter months at two key locations: the Yare Valley in East Anglia and the Slamannan Plateau in Stirlingshire, Scotland

How Long Does A Taiga Bean Goose Live?
Typically, the Taiga Bean Goose lives for around 7 years, but there are instances where it has survived much longer. The oldest recorded Taiga Bean Goose lived for 25 years and 7 months, according to ringing data.
This species, which is among the declining goose populations in the Western Palearctic, faces threats such as hunting, habitat degradation, and climate change effects on their breeding sites.
How Fast Can A Taiga Bean Goose Fly?
The flight speed of a Taiga Bean Goose can range from 50 km/h (31 mph) to 113 km/h (70 mph) with a favourable wind during migration. This speed is necessary for their extensive migrations between breeding and wintering grounds.
Are Taiga Bean Geese Aggressive?
Yes, Taiga Bean Geese can be aggressive, notably when they feel their mate, young, or territory is at risk. They tend to use loud noises and physical force to fend off possible threats, whether from animals, other birds, or humans.
This behaviour is more noticeable during the breeding season when they are defending their nests and young. Outside of this season, however, Taiga Bean Geese are generally more social, often migrating and feeding together without much conflict.
What Is A Taiga Bean Goose’s Habitat?
The Taiga Bean Goose nests in taiga habitats, favouring various wetland settings like ponds, lakes, wooded tundra, and boglands. When winter arrives, they travel to milder climates, where they can typically be spotted in open farmland and wetland areas such as marshes.
How Long Does It Take For A Taiga Bean Goose To Build A Nest?
Selecting a site and constructing a nest might take a few days as they need to gather and arrange the right materials. Taiga Bean Geese often nest on boggy ground, preferring higher ground like hummocks to prevent flooding or rising water levels. They use grasses, moss, and other plant materials to build their nests.
Eggs
Let’s look at some interesting facts about Taiga Bean Goose eggs, including their laying season, egg count, appearance, and hatching time.
When Do Taiga Bean Geese Lay Eggs?
The breeding season for Taiga Bean Geese generally starts in April, with the majority of eggs laid in May. However, local weather conditions can sometimes cause delays in the beginning of the laying season.
How Many Eggs Does A Taiga Bean Goose Lay?
A Taiga Bean Goose generally produces four to five eggs each breeding season, with the female being the only one to incubate them.
What Do Taiga Bean Goose Eggs Look Like?
Normally, Taiga Bean Geese lay eggs that are white. These eggs tend to be quite large, around 84 mm by 56 mm (3.3 in by 2.2 in), and they do not have any marks on them.
How Long Do Taiga Bean Goose Eggs Take To Hatch?
It generally takes Taiga Bean Goose eggs around 25 to 29 days to hatch. The female handles the entire incubation process, ensuring they are properly tended until they hatch.
Chicks
Let’s take a closer look at the life of Taiga Bean Goose chicks, from their numbers to when they open their eyes and start flying.
How Many Chicks Does A Taiga Bean Goose Have?
The number of chicks a Taiga Bean Goose raises is determined by the number of eggs that hatch from their clutch, which is usually 4-5 eggs, and the conditions of their environment and the presence of predators. In the best scenario, all eggs hatch, resulting in 5 chicks.
When Do Taiga Bean Goose Chicks Open Their Eyes?
The chicks of the Taiga Bean Goose are precocial, meaning they are born quite mature and mobile, able to leave the nest soon after hatching. They have their eyes open from birth, allowing them to follow their parents almost immediately. Their olive-brown and yellow down provides camouflage, helping protect them from predators.
When Do Taiga Bean Goose Chicks Fledge?
Taiga Bean Goose chicks usually take their first flights about 40 days after they hatch. This is when their flight feathers grow in, allowing them to fly. They stay close to their parents during this time, learning to find food and explore their surroundings.
The young geese stick with their parents through the autumn and winter, becoming independent right before returning to the breeding grounds in spring.
