Well perhaps one could put  some sort of anmation into an otherwise inert 
owl,  (sound,  lights, vibration,  or motion) that could be triggered by 
this Very cheap Radar Sensor from Wal-Mart  (details below):

Highly detailed hacker  info at sites below,. or Google Radar   +Wal-Mart to

get a lot of hobbyist hacking info on the $20.00 X band Radar.

On sale after Christmas for around $20.00,  the real, working  X band 
doppler radar toy for kids could be employed as a sensor, mounted on the 
tower, pointed up towards the antenna/bird perch, and once bird activity,  
caused motion to be detected by the radar;
(you would have to find and tap a  signal source somewhere in the radar 
circuit, but somewhere there would be an audio doppler signal product from 
the X band mixer, that drives the digital speed readout  (all this For $20 
retail!!) )  use the signal to drive a switch  or relay to key the noise 

For a noise maker, you could use the signal to trigger, say, a battery 
operated cell phone vibrator in the plastic owl, a lamp inside the owl, or a

noise maker in the owl (skreech)   or or other scary stimulus to the birds 
that would get them to leave.  Maybe just a cell phone vibrator (dirt cheap 
at surplus sources) Ty-wrapped  to the boom of the antenna, to give a 
surprizing  buzz to the bird's feet  on the command of the radar sensor....
Maybe just a periodic vibrator buzz to the vibrator that sends a mechanical 
buzz every few minutes to the antenna....
