Considering the urban environment as a new ecological system rather than a degraded environment, two different groups of birds inhabiting them can be distinguished: (1) the omnivorous species with generalist habits that get easily adapted to the abundant food resources available in the urban areas (eg garbage), and (2) non-generalist species that find in the urban environment the resources they normally exploit in their natural habitat (Clergeau et al .

Many raptors breed in the winter months, because of the abundance of migratory birds. (treetake.com)
The claim that migratory birds are responsible for the long-distance spread of highly pathogenic avian influenza viruses of subtype H5N1 rests on the assumption that infected wild birds can remain asymptomatic and migrate long distances unhampered. (cdc.gov)
Migratory birds as well as trade involving live poultry and poultry products have been suggested as the most likely causes of dispersal of the virus ( 1 - 3 ). (cdc.gov)
Several outbreaks in Central Asia and Europe of HPAI (H5N1) among wild bird populations that were apparently not in contact with domestic birds led to an increased interest in the potential role of wild migratory birds in the long-distance dispersal of the virus. (cdc.gov)

These are often self-injurious or harmful to other individuals, and can include feather and toe pecking, cannibalism, stereotypy, vent pecking, as well as abnormal sexual behaviours such as chronic egg laying. (wikipedia.org)
Cannibalism in birds of captivity is a behaviour often linked to feather pecking. (wikipedia.org)
Since feather pecking leads to increased food consumption due to heat loss through the skin of the bird, and feather pecking is an already aggressive behaviour that consists of cannibalistic qualities, cannibalism is a common consequential effect. (wikipedia.org)
Vent pecking, like feather pecking, is a gateway behaviour to cannibalism due to its cannibalistic features of hostility towards another individual that involves the aggressive tearing and damaging of the skin and tissue. (wikipedia.org)
The reasons are unclear - perhaps combat, courtship or cannibalism - but such behaviour was probably very common for around half of all individuals carry the resulting scars. (scienceblogs.com)
