the video begins with D14 scree-ing, his usual tactic for getting fed.

mom does a check of the food stores & decides days-old meat jerky isn't good enough for the next feeding. she flies up to a branch & calls dad. the best explanation is she wants something fresh, which has more moisture in it. the eaglets get all their moisture from their food, since they can't leave the nest yet to drink.

dad returns shortly with a fresh fish. he eats some & begins feeding the eaglets. mom flies down & has a conversation with dad. apparently she wants to feed the eaglets. he eventually leaves & she begins to feed them.

dad's vocalizations are interesting here, involving whistling sounds. whistling sounds are easily produced through holes (think flutes). the eagle tongue has a hole in the back of it, so the whistling sounds are probably produced in this way. as the eagle lacks vocal cords, this would give them a broader spectrum of vocalization. i've heard that some researchers believe the hole helps the eagle breathe while swallowing food. however, the mechanics of this elude me. in order for that to work well, the eagle would possibly have to swallow their tongue backwards down their throat to provide a breathing hole while swallowing. keeping the tongue in normal position would probably allow the hole to be mostly covered by food. in my opinion, the hole has a different function: to aid communication.

whether dad said "yes, dear" & left, or complained first, is anybody's guess.
