However, unlike many animals, Bewick's Swans change their habitat through the year by migrating. This is because they have different needs at different times of the year. Once winter sets in, and food supplies are frozen, the birds fly south to warmer, ice-free areas such as Britain and the Low Countries. Here, they can again find food and shelter. Threats to Habitat.
Habitat destruction is a major threat to wildfowl.
Pylons are a hazard for big birds like swans which cannot quickly manoeuvre to avoid them. Increased leisure pursuits such as water sports may cause disturbance and illegal shooting of protected species, such as Bewick's Swans, unfortunately continues. Conservation of Habitat. Fortunately, organisations have been formed to protect both the wildfowl and their wetlands homes. This will help to ensure that swans like Abelhard and Pedro can survive and prosper.
