And how hungry are you?

This bit of footage from BBC News is of a pelican altering his habits just a bit.... This isn't the only time this has happened--as this footage shows.
The question that this raises for me is, does this have anything to do with the projected collapse of worldwide fish stocks? Or is this behaviour just something we haven't talked/written about? You know, like the tremendous amount of homosexual activity found across the animal kingdom that researchers just never mentioned. (Or check out Bruce Bagemihl's book Biological Exuberance, or Joan Roughgarden's Evolution's Rainbow for a different take on sexual behaviour and evolution).
I notice that the pelican behaviour above is taking place in parks--neutral spaces where human/bird interations are increased and wild behaviours are set aside--so the question comes up: is this a "normal" or common behaviour, or is the pelican just taking advantage of an unusual situation? That a pelican is eating a pigeon, well, considering the size and volume of their normal diet, it's not too much of a stretch to eat something pigeon-sized. But would the opportunity arise in a non-park setting?
BTW, when it comes to park settings and unexpected behaviour, this bit of video is good for a chuckle.
