If you want to include some behavioural adaptions, then building a nest in a burrow within the bank of a creek could be included, as could their monogamous nature (forming a mated pair), and their tendency to defend their territory from other kingfishers.
Hope this helps.
I need adaptions like for example:
Big eyes -To see well and far
Long pointy beak - To grab food from underwater
ect ect,
I don't know if these are true, but please give me adaptations like that.
