FUNCTION:
FUNCTION Safety in number More eyes and ears on the lookout for predators Defences against predators: Eg . Dense formations are dangerous for stooping birds as they risk injuries. Foraging efficiency increased More eyes to spot food when during winter months.
FUNCTION:
FUNCTION Improved aerodynamics Saves energy in flight
FUNCTION:
FUNCTION Learning from the group The young can learn from the whole flock as well as from the parents Roosting To share heat and save energy
CAUSATION:
CAUSATION Increase in survival chances Energy saving Responses to stimuli
DEVELOPEMENT:
DEVELOPEMENT Development occurs trough learning From the parents From the flock
EVOLUTION:
EVOLUTION Adaptations against predation More competitive Less energy needed for defence
