Palm Beach Zoo and Phoenix hold Beautiful Fruit Dove.
Louisville holds Jambu and Wompoo Fruit Doves.
This 2018 list (
https://www.toledozoo.org/wp-content/uploads/2018/04/Bird_Overview.pdf) gives an overview of the birds on exhibit at Toledo. Some birds from that list are already listed here, while some listed here are *not* on that list. Here are the birds that are on the overview but not this thread: Chestnut-bellied Sandgrouse, Blue Ground Dove, Speckled Pigeon, Mauritius Pink Pigeon, Peruvian Pigeon, Plain-breasted Ground Dove, Red-throated (Cinnamon) Ground Dove, Crested Quail Dove, Namaqua Dove, "Partridge Bronzewing", Jambu Fruit Dove, “Ring-necked Dove”, “Pink-headed Turtle Dove”, and Mourning Dove.
Capron Park holds Beautiful Fruit Dove and Black-naped Fruit Dove.
Mill Mountain Zoo holds Nicobar Pigeon.
Lowry Park has Black-naped Fruit Dove and Luzon Bleeding-Heart Dove.
Tracy Aviary has Black-naped Fruit Dove and White-throated Ground Dove.
Hogle does *not* have Mourning Dove as previously reported; however, they do have Pied Imperial Pigeon.
Zoo Boise's new Gorongosa NP-themed exhibit complex has Emerald-spotted Wood Dove.
Philadelphia and Saint Louis hold Mariana Fruit Dove.
Lincoln Park has Jambu Fruit Dove, as do Roger Williams Park and Tulsa.
Rio Grande (Albuquerque) and Texas State Aquarium have Socorro Dove, with the former holding ~1/3 of the global population apparently. Smithsonian had them in the Bird House; it is unclear if they still possess the species now.
I also found (cue trumpets) A SPECIES LIST FROM 2018 FOR DENVER. Unfortunately, it is unclear how many of these birds remain at the zoo since the Bird House is now closed and is scheduled for demolition. Relevant species here are: Nicobar Pigeon, Victoria Crowned Pigeon, Sulawesi Ground Dove, Beautiful Fruit Dove, Black-naped Fruit Dove, Grey-capped Emerald Dove, Jambu Fruit Dove, Laughing (Senegal) Dove, Mariana Fruit Dove, and both species (Luzon and Mindanao) of Bleeding Heart Dove.
