The nutcracker is an omnivore, but subsists mainly on pine nuts, burying seeds in the ground in the summer and then retrieving them in the winter by ...
Many invertebrates, such as the carrion and burying beetles, [6] as well as maggots of calliphorid flies (such as one of the most important species in Calliphora vomitoria) and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains.

Bird-eating raptors also tend to show greater sexual dimorphism than other raptors, with the females being larger than the males. [ 2 ] Some avian avivores such as the shikra , besra , Eurasian sparrowhawk , and sharp-shinned hawk catch their prey by flying from cover in a tree or bush, taking their prey unawares.
Frugivore seed dispersal is a common phenomenon in many ecosystems. However, it is not a highly specific type of plant–animal interaction. For example, a single species of frugivorous bird may disperse fruits from several species of plants, or a few species of bird may disperse seeds of one plant species. [3]

Unusual for birds of prey, the palm-nut vulture feeds mainly on the fleshy fruit-husks of the oil palm and on the palm-fruits of Raffia palms, as well as wild dates, oranges, other fruits, some grains and acacia seeds. [13] [14] These fruits make up over 60% of the adult bird's diet and over 90% of the juvenile bird's diet. [10]
