Quite a bit of news since then.
@zoomaniac, Ringer had actually given birth about a month before your post (lol). The calf died minutes after birth. Nobody knows who the sire was, could've been Juan, Ross, or Pepe.
Whisper is now pregnant, the sire of her calf is Naluark.
Of the babies born at Discovery Cove, two are now dead. I don't know if somebody already mentioned this. Nero died of a vaccination reacting in November 2016, and Star died from "failure to thrive" in October 2016.
SeaWorld Orlando and Discovery Cove have been exchanging dolphins quite a bit lately. CJ was sent to Orlando's Dolphin Cove, Tyler and Roka are now in Animal Care with many other adult males. Dolphin Days is now open, only featuring Tiger, Diego, Marble, Starbuck, Phil, Clyde, Baretta, Bubba, and Alejandro. Alpha and CJ are being used as breeders, but they left Dexter and Rascal in Dolphin Cove just in case. For the Dolphin Nursery expansion, Naia, Dash, and Ariel were sent into Animal Care, though Naia has since moved into Dolphin Cove and Yar has taken her place in Animal Care. Sasha has since moved into Dolphin Cove from Discovery Cove as well.
SeaWorld Orlando sent Lily, Starla, Aurora, Gertrude, Archer, and Nigel to Discovery Cove in late 2016 or early 2017. Since then, in February, as someone already mentioned, Lily was euthanized due to mouth cancer.
The "naked" Adelie penguin has regrown her feathers.
Dolphin Nursery's progress is unknown. I'm not sure if it's open yet, since Dolphin Days happened totally unannounced I wouldn't be surprised if this was the same way. I'm not sure why that is, they made so much hype for the upcoming Sea Lion and Otter Stadium show a couple years ago.
SeaWorld Orlando plans to open ORCA Encounter in 2018 or 2019, the show has already opened at SeaWorld San Diego.
As for the pilot whales, they can be viewed in F Pool sometimes, other times the orcas have access to F Pool. I've seen videos in which the pilot whales also had reign over other pools, presumably G. Ace and Ava tend to be more interactive compared to Fredi and Piper.
About the births in Discovery Cove, there is more information. Damara's daughter was sired by Alpha and has been named Delilah. Astra's daughter was sired by Kenobi via artificial insemination. Gala had a daughter on May 12, 2016 named Eden, sire is unknown. Frankie had a false pregnancy. Storm is a female. Titan was sired by CJ, and Nero was sired by Scott. The sires of Star and Kona were confirmed by a Discovery Cove trainer to be either Lester or Capricorn, as Roxy and Stella were not held with any other males apparently. Eden is completely unknown, could be literally any male at Discovery Cove or any male trained for artificial insemination.
