Ah, I know you from your 'Hot Spring Town' in the previous Town Music Jam! Nice to see you again here :)
Very interesting entry. It is very wild and never seems to repeat itself (something I struggle with: I always repeat). I can hear the 'alertness' theme in here and never know what to expect. Although there is nothing particularly birdlike about this song, I can imagine the motives of 'movement', 'attacking' and 'grouping' you put in, which is quite nice. Some parts like 1:30 are a bit harder to grasp, going into the 'disordered' state as you call it, and other sections are more calm like 0:30 (perhaps grouping?). The ending was a bit surprising though. Overall, it's a well-made song fitting the constant feeling of being under attack from a flock! Well done :D
And what do I read here? You have made more songs for the other enemies? Cool, I might give them a listen too :)
