Consuming high levels of pro vitamin A carotenoid, which come from plant sources, does not lead to vitamin A toxicity. This statement is true.

Vitamin A is obtained mainly from the food products we eat, but it is also synthesized in our body via pro vitamin A carotenoids like beta-carotene. When high amounts of pro vitamin A carotene are consumed in the diet of a person they are converted very slowly and naturally in our body into vitamin A in the intestine.

Vitamin A has many benefits including defense from pathogens, strengthening immune system, improving vision, and also improving overall growth and development of the body etc.

The arrival of new birds increases competition for food. This makes the birds that have just arrived have some difficulty in accessing food, as they will have to compete with the birds that are already on the island. This makes the novice birds look for food plants they already know, which delays their adaptation to feeding new plants they do not know.
