ANOTHER BIG BIRD WONDERING AROUND

Last birds I posted was ibis.
A bird located all over south Florida.
I like they go through my grass and eat all the unwanted bugs.

Now I see another birds. They are bigger than ibis.
I don’t see them often.
They walked in group too.
They are big like turkey.
They look grey

Their bec is not that long as ibis.
They do not run away from me.
I stay away though.
They were in a trip cause they don’t leave in the area.

I did capture quite a few shots.
Enjoy

Since I install the new iOS I have the opportunity to change the size of each picture.
The middle one could be low grade due to more compression.
Do you know this bird ?
