Bird Feed

Everything you’ve ever wanted to know about the diet of different birds

Birds are incredibly versatile when it comes to their diet. They have adapted to consume a wide variety of food sources, including seeds, insects, fruits, nectar, fish, and even small mammals and reptiles. Understanding birds’ diet is crucial for providing appropriate feeders, attracting specific species, and contributing to their overall well-being. At Bird Sector, we explore everything you ever wanted to know about birds’ diet. Whether you’re a bird enthusiast or simply want to appreciate these feathered creatures, remember that bird feed comes in many forms and offers a window into their fascinating lives.

Seeds and Grains

Seeds and grains form a significant part of the diet of many bird species. These include:

  • Sunflower seeds
  • Millet
  • Corn
  • Wheat
  • Oats

Birds such as sparrows, finches, and pigeons are particularly fond of seeds. They have specialized beaks that allow them to crack open shells and extract the nutritious kernels within. Bird feeders stocked with various types of seeds can attract a wide variety of birds to your backyard.


Insects are a vital source of protein for birds, especially during the breeding season when they need to feed their young. Some birds even rely solely on insects as their primary food source. Common insects consumed by birds include:

  • Beetles
  • Grasshoppers
  • Caterpillars
  • Moths
  • Ants

Warblers, flycatchers, and swallows are excellent insect hunters. They use their agility and sharp beaks to snatch insects mid-flight or forage for them among leaves and branches.

Fruits and Berries

Fruits and berries are a delicious and nutritious part of many birds’ diets. They provide birds with vitamins, minerals, and antioxidants. Some fruits that attract birds include:

  • Apples
  • Berries (blueberries, raspberries, blackberries)
  • Grapes
  • Cherries
  • Oranges

Birds like robins, thrushes, and orioles have a special fondness for fruits. They help disperse seeds by consuming the fruit and then spreading the seeds through their droppings.


Nectar is a sweet, sugary liquid found in flowers, and certain bird species have evolved to feed on it. They have long, slender beaks that can reach deep into the flower to access the nectar. Hummingbirds are the most well-known nectar feeders, but other birds such as sunbirds also enjoy this energy-rich food source.


Water-dwelling birds like herons, kingfishers, and cormorants have a diet that includes fish. These birds are expert divers and fishermen. They plunge into the water to catch fish, and their beaks are specially adapted for gripping slippery prey.

Small Mammals and Reptiles

Some birds, particularly raptors, have a diet that includes small mammals and reptiles. Owls, hawks, and eagles are skilled hunters that feed on rodents, snakes, lizards, and even small rabbits. They have sharp talons and powerful beaks to capture and tear apart their prey.
