After listening carefully for a second time, I can hear the good use of instruments that subtlely represent the pecking sound: a synth (I don't know what it's called), a frequent and coherent use of hi-hats and snares.
One of my observations is similar to Nick Schuitemaker's: The song might not fully represent the encounter/battle phase but is very good as an anticipation/warm-up phase, which is not necessarily a bad thing, but rather a refreshing yet logical take on a pigeon song. Good work!
