Nevertheless, if we try our best to learn and record the types of foods eaten, we can discover many things. Birds must be able to fly at all times, so eating a large quantity of food and digesting it very slowly is not appropriate. Birds need to eat highly nutritious foods which can be easily digested. Therefore, they mainly eat animal-type foods. Even when eating vegetable-type foods, birds try to find fruits, seeds, and flower buds, etc., due to their high nutritional content.
Tits are dexterous.
They can be seen dangling from a branch to get food or, as in the above photo, eating the inside of a seed or fruit by holding it with its legs and breaking the core with its chisel-like bill. Even though some closely related birds catch their food in the same place, e.g., Mongolian plover and Kentish plover, or grey-rumped sandpiper and common greenshank, the types of foods they eat and the way they catch their food are slightly different for each type of bird. Let's keep this point in mind while watching birds. In addition, many birds eat artificially processed foods, in particular snacks or meat pieces thrown into the garbage. Jungle crow are famous for looking for food in raw garbage.
