I'm going to bring the bird in the day after tomorrow seeing as its a long drive to the conservatory.
The baby has;
-Gray pin feather that move into a tan color
-white belly
-naked along neck and under wings
-longer neck & very , long legs
-beak is longer but not longer than the head
-beak is wide and yellow
-when it opens its mouth its all yellow inside

It chirps and makes a weird shrieking noise as well.
It's about the size of my palm and almost 5 inches when standing.
Can anyone tell me what it is??
