strange bird call.wav

This is quite a recording of a bird, not sure of the type; happy to hear from all you bird call experts..it started off sitting on a branch literally feet away from my car and the result is the first 10 seconds or so of this wave, then it flew off into distant trees which is where you hear the increased urban noise come into it..All my best bird call recordings seem to come after I spread a few chips around on the ground near the recording equipment.. I got the feeling this bird was telling me to get the hell away so it could eat without me bothering it, but when it realised I was far too interested to leave at that point, it flew to a nearby tree and continued it's rant..hope you enjoy :)
