Here's one way. I'm sure there are probably better ways, but here's the rough idea. I'm sure LightBulb or one of the other smarter than me's can clean this up, or even offer something easier.
Note: tested off line using: #Show Birdie is <pattern>.
Trigger Pattern:
Birdie is (%w).
Command:
#var LengthCount _nodef _nodef _nodef
#var LoopIndex _nodef _nodef _nodef
#var TempString _nodef _nodef _nodef
LoopIndex = 0
TempString = ""
LengthCount = %len(%1)
#WHILE (@LoopIndex <= @LengthCount) {
TempString = @TempString%copy( %1, @LengthCount - (@LoopIndex - 1), 1)
#math LoopIndex {@LoopIndex + 1}
}
#show @TempString
Birdie is flying.

Same general approach. Loop through the string from back to front.
#VAR backwards {drib}
#AL flashstar {
#VAR forwards %null
#LOOP %len( @backwards),1 {#VAR forwards {@forwards%copy( @backwards, %i, 1)}}
} |
