Question

Hello Everyone, I wanted to know that is food a reason for migration of brids ?​

Answer 1

Answer:

Birds migrate to move from areas of low or decreasing resources to areas of high or increasing resources. The two primary resources being sought are food and nesting locations.

Explanation:

Seasonal migration enables birds to avoid the physiological stresses of unfavorable climates and to exploit food supplies that are available for only limited periods each year.

Most species are born with migration routes genetically encoded in their brains. The timing of their return, too, is governed by an internal clock that tracks the changing ratio of daylight to darkness as winter progresses, and longer days trigger their instinct to head north.

But with the wind behind them, birds can easily cover 1,000 km (625 miles) in just 24 hours. Wind allows some birds to perform amazing flying feats. Bar-tailed godwits have been recorded migrating from Alaska to New Zealand – a distance of almost 11,000 km (6,800 miles) – in just six days.
