Diagram:
The duck was folded per diagrams in Teach Yourself Origami by John Montroll, page 35.

My experience:
The duck was made with a focus on using the outside reverse-fold. The folds are layed out to end up with a solid colored model when complete.

What’s interesting about folding this is the inital folds get unfolded. Then new folds are made with an outside reverse-fold to make the head/neck. The tail is then reverse folded as well.

To even it out, the bottom point it folded behind to parallel the top.

Not as rewarding as some of the other designs for how it comes out, but it’s good for practice.

This model took me several attempts to not do with crumples.

A set of these on a table would be a nice decoration.

Personalizing:
The angle of the tail and head can both be adjusted.
The back, the mountain fold, could be folded in as well to create a greater slop towards the tail.
