Do Crows Eat Insects? ( Like Beetles, Bugs, And Pests)

Crow’s diet is quite diverse as the birds have great adaptability toward manmade and natural foods. They are believed to eat almost anything that they find. 

My curiosity to know about their diet increased when I saw them picking and eating something from the hidden little spots in my garden. I searched about their diet and eating habits later on to satisfy my curious self.

With the help of my research, I have compiled all the information below to help you know about whether insects are eaten by crows. 

Do crows eat insects?

Crows are omnivore birds having insects as a large part of their diet. They eat a variety of insects ranging from small to large. 

They are considered as highly opportunistic birds as they eat anything that they find in their way. But the most easily available food to crows are insects and thus, the birds do not have a day without eating any insects. 

The crow even helps farmers by consuming several insects that are considered harmful to the crops in agricultural areas.  Different species of crows have differences in their diets but insects are part of each of their food. 

The insects are the source of protein in their diet that helps the birds to remain healthy. Especially while raising young, the demand for insects as food increases. The inadequacy of the protein-rich nestling food, such as insects, may lead to the short-term survival of the crow’s young.

The young crows eat a larger portion of insects.  It is estimated that the intake of insects in nestling crows is one-third more than the adults.

  • Caterpillars
  • Wasps

The small species of insects are rarely eaten by crows. However, the ants are the exception to this. They almost eat terrestrial insects found on the surface of the ground, the base of the plants, under the objects, in the domestic animal’s dung, or underground. 

The coprophagous insects are constantly eaten by crows whereas the arboreal insects are rarely consumed. The insects with bright colors are more attractive to these birds and are eagerly eaten by them. The golden color is the most attractive of all the colors.

The birds seem to prefer insects having hard covering more than the ones with soft bodies. They also have a special liking for insects with strong or pungent odor or taste.

The average percentage of insects eaten by crows is estimated to be around 26 percent of their food in a year. A crow family can consume almost 40,000 insects including caterpillars, grubs, and armyworms in a nesting season. 

The amount of the intake of insects depends hugely on the seasons. The crows have the largest portion of insects in their diet during the breeding season.

Crows forage for insects mostly during the day. Their eating patterns indicate that they feed very often when they are most active.
