As natural food supply for the birds decreases, many species will become rare.
Birds are very busy during spring. First they must find a partner, then a living space, lay eggs and raise their young. During summer they moult and get a new coat. In the fall they prepare for winter and during winter they need more fat to keep themselves at the right temperature. Birds can lose 10% of their body weight during a cold night.
