1. BIRD MIGRATION

2. Why do birds migrate? Birds migrate to move from areas that have low or decreasing resources The two most important resources being looked for are food and nesting locations. Birds that nest in the northern hemisphere often migrate towards the north in the spring to insect populated areas, As winter approaches, and the availability of insects and other food resources drops, the birds move south again. Escaping the cold is a motivating factor but many species, including hummingbirds, can withstand freezing temperatures as long as a supply of food is available.

3. Southern Royal Albatross Southern albatross mainly migrate around the southern ocean and are commonly seen in New Zealand. They nest and breed on the Campbell Islands, Then move south towards Antarctica Each bird often fly the same migration paths each year Their migration paths are recorded though satellite, some fly thousands of kilometres. One bird named princess Anne flew a total of 6,000 km in about 16 days.

4. Experts advice Laurence Sullivan( my uncle) He is a Ecologist he works a lot with birds and nature. What are the hazards of birds migrating? Well, when sea birds migrate they need rest stops called wetlands and most of them are being flooded by the ocean or destroyed by rubbish caused by us humans. Another reason not quite as serious but they are easily confused with human streetlights or bike lights. How do birds navigate while migrating? Different birds use a range of techniques like using the magnetic field. At the centre of the earth there is ball of pressurised melted burning hot iron. Now it is spinning and creating the magnetic field. And birds are able to red the magnetic field to figure out north and south. Also sometimes it is in their DNA and it just comes naturally. How do birds prepare to migrate? Bird preparation for migration is really just eating loads of fat. And a lot of sleep. Now the reason for eating fat is because it is lighter and protein Is much more heavy.

5. Push and pull factors. Push factors. Freezing temperatures. Lack of food. Lack of nesting habitats or Homing resources. Dangerous lifestyle lots of Hazards. Mating and to lay eggs. Pull factors Better nesting habitats resources. Humid temperatures. More insect populations to take advantage On. Less hazards More bird populated areas
