The Gullet is the tube in a birds throat which allows a birds food to pass down into it's "Crop" where it is ground down before passing into the birds stomach and alimentary tract, and then passes out the waste at the other end.

You can tell when the crop is full by looking below the birds beak between it's breast bones, it will protrude from it's chest. You can see Icarus's full crop just under his neck in this photo. When I first started feeding him, he ate .03 CC's every hour on the hour. Today, at a week old, he eats 2.5 CC's every hour, except at night when he sleeps a straight four hours. Talk about worn out! Thank goodness this will only last a few short months. Honestly, I don't know how I handled all those sleepless years when my kids were but babies.
