Good advice for children is to travel in a group, as birds usually prefer to target individuals.

In a first series of tests, they found that the birds preferred other birds' odors over their own.

I began to wonder whether birds might prefer to take their chances in a radically privatized America.

Surveys have found the bird prefers to live in small, localised populations.

Deforestation has destroyed much of the dense rain forest these birds prefer.

Furthermore, these birds often prefer to run rather than fly, especially in dense habitat.

The birds prefer open wooded areas with hollow-bearing trees to build nests in.

Although the birds prefer thorny trees, they sometimes use avenue trees in urban areas.

Will you have the kindness to tell me whether the birds prefer one colour to another?

However, it makes sense that a bird walking across the street prefers walking to flying.
