I was at an event on an airfield, one display featured birds of prey... As soon as the first bird came out all the Skylarks disappeared. As each bird was brought out more birds disappeared until a Peregrine Falcon was brought out; absolute silence, no sign of any bird anywhere, even the Crows that were in a hedge at least 1km away were gone! Being the fastest mammal in the world (200mph) gets respect in the avian world!
Nearer to home my hens do not like the Seagulls helping themselves to the bird feeders! Worthy of Youtube
