There are over 40 species of Gulls across the world.

Where are Bald-Eagle and Seagull found?

Gulls are water birds. They are typically found near coasts, especially during summers. However, they have become common even at inland waterways like rivers, reservoirs, and lakes. They can adapt to any region as long as there are food sources there. Consequently, Gulls are visible even inside cities and towns. Gulls exist everywhere in the world.

Nests are generally positioned on top of large trees in the vicinity of water sources. The eggs are a pale white and shaped oval. Both partners share the task of incubating the eggs for about 35 days. The young ones fledge when they are eight to 14 weeks old.

Gulls build their nests in their habitats. It could be at cliffs, coasts, islands, trees, and rooftops as long as they are safe, have food sources nearby, and inaccessible to predators.

Are Bald-Eagle or Seagull migratory birds?

Bald Eagles usually reside in their territories throughout the year. The ones living in Canada and Alaska travel south to spend the winters in central and southern parts of USA.

Gulls are generally migratory. They move from northern hemispheres during winter to regions where there are abundant food sources. The birds from Canada and North America move to the tip of South America or parts of USA where the temperature is not freezing. The Black-Headed Gull migrates from UK to southern Europe, the Middle East, and Africa. Similarly, Gulls migrate from China to Thailand, and from Russia and Siberia to the Indian subcontinent. Some Gulls living on French and Spanish coasts and other warmer regions do not migrate. Additionally, Gulls that have settled in cities where they get easy access to food from human refuse, safe nesting places in rooftops, and warmth from buildings may not migrate.

The population of Glaucous-winged Gull has declined by 50 percent in Georgia Basin, while the numbers of Gulls in Canada and the UK are also falling drastically. This has been attributed to loss of habitat, pollutants, and poor food quality.

Can Bald-Eagle and Seagull fly?

Bald Eagles fly by soaring high with the use of thermals and wind currents. They manage their speed by altering the position of their wings. During long migration, the birds rarely flap their wings in order to conserve energy. The average flying speed of Bald Eagles is 75-100 miles an hour.

Gulls are highly skilled in flying. They have expert control on wind and thermals, and can execute complex manoeuvres. They can fly at speeds of up to 28 miles per hour.
