you're quite wrong. No composition work whatsoever has been done (I can share you the original RAW file). This is a single-exposure HDR -- tone-mapping has been performed for a single RAW file. There's nothing "fake" in it -- in this case the tone-mapping operator has done a 12->8 bit quantization. Had I used more exposures, I could've grown the number of bits to perhaps 13,14,15 -- but, as you said, multiple exposures don't work well with moving objects.The reason why the bird looks a bit "pasted" is that I took a 12mm wide-angle lens and approached the (rather tame) bird very slowly -- I managed to get within inches of it before it took off. Wide-angle lenses aren't usually used for such close-up shots.
