Black Swifts
Anti-predator behaviour
Where the Desna River makes a turn the bank is steep and inhabited by swifts who dig holes in it (Avoid contact with predator strategy).
Yesterday we observed their anti-predator behaviour: a crow was ruining their holes for eggs, and their strategy was MOBBING - all of them were making it fly away.
It always surprises me that whenever we come up to the river with Rey, my dog, the swifts start flying quickly just over us - I guess this is a making-us-go-away strategy.
