I had to read this thoughtfully that's why I didn't comment at the first time.
The words "beast" and "dove" were a bit confusing as I thought in the beginning that the poem is about the process of predatory, but it turned to be about something else :)

You made google "Dove mating rituals", the female builds the nest, the male brings the food.... We "the females" always rock, don't we?

Great job, Ingrid, very interesting Haiku.

Hello Ingrid,

Lovely neat little package here...

Grooming her feathers

In three words you have painted a picture of a female bird preening herself. This form is about creating lasting images and you have done so in the first line.

dove obeying nature's laws

This line tells me which breed of bird. A dove - well there is all sorts of symbolism with this breed - biblical and of course a bird symbolizing peace. I do not think though this is the message you are portraying. This female Dove is acting as intended. Programmed by mother nature to preen and groom. Well, we know that there are necessary oils secreted from glads into the feathers to keep them healthy and to resist water. In this line I wonder what will be the 'ah ha' moment in the last line.

mates with next in line.

Alright, I was not expecting that. This line suggests that this grooming is a mating ritual. Next in line seems to mean that there are a line of male Doves waiting for similar attention. If that is so I am coming back in the next life as a Dove?

Great little Gem Ingrid.

(((hugs)))

Brought a smile to my face the end of this. Excellent little piece. Well done. And congrats on this week's HM!

Another short but well written piece, saying much, but in just a few words. Well done! Good writing.
