Is this Egretta garzetta or gularis? (1 Viewer)

One of our birders made these three photos of a small white heron (egret) in a very well-birded urban hotspot in Belgrade. The most logical choice in our area is Egretta garzetta, although they are already leaving for south (mostly summer visitors). However, several persons remarked that this bird looks strange and some have suggested Egretta gularis or a hybrid.
If you are familiar with the other two forms, may you please judge this bird?
Thank you in advance.

It is a Little Egret Zheljko, IMO. Not all little egrets make to be the immaculate Beau Brummells of the bird world!

Not sure if that is grey fethering or if the bird is dirty?

Thank you! I am not sure how clean the bird is, as this is a downtown location and there might be anything in the water. I alerted everyone on the local forum to take detailed pictures of any white egrets in this area (as black-necked grebes have already appeared, with juveniles in tow, everyone goes to this location to take their photo).
