Difference Between Crows, Ravens, And Blackbirds? (Find The Difference)

Difference Between Crows, Ravens, And Blackbirds? (Find The Difference)

Birds are the most beautiful creatures in nature. They are warm-blooded vertebrates with features, wings, and toothless but very sharp and strong beaks.

Birds have hollow bones and air sacs, which reduce their weight and help them in flying. They breathe through their lungs.

Birds are of two types i.e running birds and flying birds, like kiwi, rheas, ostrich, emus, and road runners, are examples of running birds. They have weak wings but solid legs and run very fast.

Crows, eagles, sparrows, pigeons, blackbirds, and ravens are flying birds. They lay hard shell eggs and have a very high metabolic rate.

While ravens have wedge-shaped tails that are more noticeable when flying, crows have rounded or squared-off tails. Crows have a smaller bill and are smaller than ravens. Crows and ravens are both totally black, down to their feet and beaks.

Birds have a compound and well-developed nervous system. Many birds are recognized to be extremely intelligent and teachable. 

Let’s get into the details!


It is the branch of zoology, and in this, we can briefly study birds and their natural habitats. The word ornithology comes from a Latin word that means bird science.

Types of Birds

There are over 1000 species of birds all over the world, and all are different from each other. Scientist groups them into 30 categories. Some of them are:

  1. Diurnal birds of prey (Accipitriformes)
  2. Waterfowl birds (Anseriformes)
  3. Hummingbirds &swifts (Apodiformes)
  4. Kiwis & extinct birds (Apterygiformes)
  5. Horn bills & hoopoes (Coraciiformes)
  6. Corvidae (Oscine passerine birds)
  7. Pigeon and dodos (Columbiformes)
  8. Emus & cassowaries (Casuariiformes)
  9. Night jars, frog mouths & oil birds (Caprimulgiformes)

Now, I will discuss the difference between crows, blackbirds, and ravens.

Crow and Raven belong to the same order Corvidae, also known as the Crow family. There are almost 133 members in this family.  But the blackbird is a part of the Turdidae family.

The blackbird is an elegant bird with a melodious voice, and these birds live close to humans.

Common blackbirds were first introduced to Melbourne (Australia) in the 1850s. It mainly lives in Europe, North, South, and Central America. They are often found in Africa and Canada.

Different species have diverse ranges and distributions. Some birds migrated seasonally, and some lived in the same place, depending on their region.

They successfully live in bushland habitats. You mostly find blackbirds in orchards, the countryside, and parks. 


  • Life span: 2.5 – 21 years 
  • Weight: 80 – 120 g
  • Length: 24 – 25 cm

The blackbird builds their nest in a cup shape, with dry grass, mud, and some fine grass. It usually places this in shrubs or low bushes, but they also use tree holes.

  • The breeding period of blackbirds starts from March to July.

Ravens are omnivores and highly opportunistic.

They will eat small animals, eggs, grasshoppers, beetles, scorpions, buds, cereals, grains, berries, and fruits. They also consume animals and human wastage.
