How many earthworms does the swallow feed a day?

It is appropriate for swallows to feed 50% to 75% of their own weight earthworms a day. When feeding swallows, it is suggested to determine the appropriate amount of earthworms according to the following factors:

1, age and weight: Young swallows may need less food, while adult swallows may need more.

2. Activity level: If swallows have more activities, such as flying and exploring, they may need more energy, so they need more food.

3. Swallow's health: If the swallow is healthy, has a normal diet and has a moderate weight, then the appropriate amount can be determined according to its appetite. The swallow's diet usually depends on its age, weight and activity level. Generally speaking, a swallow needs to consume about 50% to 75% of its body weight as food every day. Earthworms are one of the main foods of swallows, but the specific feeding amount may be different according to the actual situation.
