Do birds eat flies?

Yes, many species of birds eat flies, especially some small birds that wait for prey. Flies are one of the common prey in many birds' diets because they are easy to catch and rich in nutrients.

Some insectivorous birds, such as swallows and bats, use flies as their main food source. In addition, many passerine birds such as house martin, kestrels, larks, etc. also often eat flies, mosquitoes and other insects. There are also some water birds such as snipes and woodpeckers, which can also obtain nutrition by eating flies in ecosystems such as lakes and rivers.

It should be noted that flies often move around garbage dumps and feces and may carry bacteria and pathogens. If birds eat a large number of contaminated flies or other contaminated foods, they may be infected with bacteria or viruses. Therefore, it is very important to keep the environment clean and ensure that the food sources of birds are clean and safe to protect the health of birds.
