HOW DO BIRDS KNOW WHEN TO MIGRATE?

Overall, the birds respond to changing daylength, but weather conditions, e.g. prevailing winds, can modify the timing; ultimately the bird’s hormones drive it to eat lots of food to accumulate enough body fat to migrate.

DO ALL BIRDS MIGRATE?

Most but not all bird species engage in north-south movements each spring and fall; grouse-like birds, owls, woodpeckers less likely to migrate; even within migratory species, some individuals stay north in winter, especially in mild winter with lots of food and cover.

WHY DO BIRDS FLYING IN TIGHT, LARGE FLOCKS NOT BUMP INTO ONE ANOTHER?

This is very difficult to study; possibly a combination of highly developed visual abilities, sensory receptors in the skin to detect vibrations from neighbouring birds’ wings,  excellent motor coordinaton, and strong reflexes are responsible.

CAN BIRDS FLY BACKWARD?

Hummingbirds are masters at it, but other small songbirds, and even large herons, can flutter backwards if pressed to do so.

WHY DO SOME BIRDS FLY IN V-FORMATIONS

Some species like geese, cormorants and pelicans gain lift from the rising eddies of air currents whirling off the bird immediately ahead of them. This saves energy in the long run.  Formation flying also prevents mid-air collisions among large birds.

WHAT HAPPENS TO EGGSHELLS AFTER BIRDS HATCH?

For precocial birds, they are left in the nest; for altricial birds, they are removed or eaten by the parents for calcium or crushed by the young.
