Glossy Ibis worth second look and more

Spent an hour trying in vain to get close to Glossy Ibis (Plegadis falcinellus) at roadside pool, gave up - and 200 metres down the road came upon this bird feeding hungrily in transient pool on mown reserve beside main railway line and unconcerned by my arrival. Several images, all full frame, the first without any tweaking...

... the second processed from same jpeg with minor colour adjustment and sharpening ...

... the third processed from Raw file, converted to Tiff, with similar colour adjustment and sharpening.

The bonus fourth is starting point of work in progress.
