Big Birds in our Parota Tree

We know when it is time for the sunset because the Yellow Crowned Night Herons squawk upon arrival to our giant parrot tree next to our rooftop penthouse.  We live outdoors so we hear and see everything.  This year, the herons didn't arrive until about a week ago.  They sit in the tree usually apart all day and might change branches a bit.  Just as the sun sets, they squawk again, and fly off to eat and we don't see them again until morning.
