The survival of a species depends on its capacities
to protect itself against climate, diseases, and
predation, and to its reproductive and feeding
capacities. So feeding is one of the essential
parameters of animal survival and, thus, knowledge on
feeding ecology is important. A specific analysis of the
prey or plants ingested is useful to examine precise
relationships between habitat, prey and predators and
to suggest adapted conservation measures for an
environment that is becoming more and more artificial.

Diet study methods in birds are various and each presents its
own interest. Such methods as direct observations, photographic
traps, vomited food analysis, and digestive tract analysis, are often
used. But the collection of regurgitated pellets or faeces reduces the
risk of stress or disturbance and does not necessitate the death of
the birds.
Moreover, this kind of material allows a specific examination of the
food ingested. This is particularly interesting in the case of studies
of endangered species.
