Brazil, Pantanal, Short-tailed Hawk, dark morph ?

Dear all,
I think I was too hasty in calling these hawks "Great Black"....both photographed last summer in the Pantanal.
I am now inclined to think that they (this is a pair) are both dark morph of "Short-tailed"... the give-away being the small white "tuft" on the forehead of one of them..., and of course the very short tail.
Also leaning towards the first one being the male and the second one the female.
Am I correct ? Thank you all in advance.
Best, ugolino

This is great black hawk for me. I think the structure is wrong for short - tailed (a slighter, less robust species), as is the cere pattern and, paradoxically the tail length which should be longer. Admit I don't understand the point about the feather tuft on the forehead of one bird : this is down or feathers ruffled by the wind rather than a key plumage feature

Great Black Hawk for me too. Names can be confusing, Short-tailed Hawk has a short tail, but Great Black Hawk have even a shorter tail...

Thank you both. I see what you mean about the overall build of these birds.
I don't know why I needed to revisit this ID... but I did, and glad that I got it right first time around.
Best wishes for the summer break, ugolino

Also, you will never see a Short-tailed Hawk perched on a fence post or out in the open. They perch in the canopy, usually in the leafy portion of tall trees.
