Structures: Buildings, walls, radio/cell towers and other constructions create collision hazards. Entire flocks panicked by human influence or natural circumstance may collide with objects which normally pose no problems.
Powerlines: Psittacines commonly use overhead line in the pre-roosting congregations. Unsafe, grounded, non-insulated or malfunctioning powerlines can result in mass injury and mortality.
Electrical Shock: electrical shock injuries can occur from nest or cavity-building activity. Freak accidents such as faulty electric structures (light poles, household connections, pirated electricity, sports field illumination) can electrify wet fields and water sources; resulting in mass casualties.
Fireworks: disturbance of roosts from fireworks can result in collision injuries on a mass scale.
Harassment: intentional harassment, especially at night roosts, can result in mass casualities.
What to Expect
Severe, multiple and complicated blunt trauma
electrical shock and burn injury
possible fall injuries
intentional projectile (guns, slingshots, etc) injury
What to Do
Capture and contain injured birds
keep them in a warm, dry, safe and secure environment
do not force water or food
warm water can be gently dropped along the tomia (edges of upper and lower beak) to encourage normal licking and swallowing
once water is accepted, warm sugar water (1:4 sugar to warm water) can be alternated
do not offer free-access water until they are able to regain normal posture
offer food only after they are hydrated
contact appropriate rescue if/when possible
minimal handling and refrain from :staring at them all the time"
visual or audible contact with other birds is desirable
ambulant and non-aggressive birds may do better in small groups (5 or less)
severe injury and hypothermia generally do not lead to good outcomes
many birds will have fatal injuries
projectile injuries will likely be fatal or require immediate euthanasia
expect a high mortality rate on birds that are found down on the ground and docile
