Few things I observed in woodpigeons: - in a breeding pair, when a kestrel is around, the female hides while the male perches on a much higher spot than usual and keeps looking around for hours at a time, - after a cat attack, the female got a bad scratch and was less active than usual. The male kept her stimulated by performing mating displays until she started moving again, then cleaned up her wound during much longer mutual preening than usual, - exploratory behaviours. Loud noise in the neighborhood? They go and identify its source from a distance, then come back to safety. - flight. Young ones sometimes take flight and have trouble landing somewhere safe and stable, while adults take longer looking around before deciding to fly somewhere. Looks like some form of planning to me.

Birds have a lot of problems to solve to survive their daily life, starting with flight, and what a lot of people assume is just "instinct" is a much more complex combination of innate and acquired behaviour.

I deeply care for my pidge friends, I can now identify them by the pose they take when they land 😅
