Phoenix Zoo is listed in Zootierliste for Varecia spec. along with both species of ruffed lemur. Is there a hybrid ruffed at the zoo?
 
Michael, the male Bornean orangutan, was recently diagnosed with apocrine carcinoma, which is cancer of the sweat glands. He’s the first orangutan ever to be documented with this disease. He’s had two surgeries so far to remove the mass, tissue, and receive injections for further detection, but seems to be handling it like a pro so far.

I visited the Phoenix Zoo over the weekend and there are a couple of changes I noticed, both from the most recent species list here on Zoochat as well as ZTL.

- Visayan warty pigs are absent from their pit style enclosure in the children's area. Instead, a young pair of Aldabra giant tortoises are present and signed.

- Also in the children's area there is an aviary containing a pair of hooded vultures and a juvenile palm nut vulture. Both species are signed. I'm unsure exactly what was in that aviary previously but it's right across from the king vultures, so they may be taking the place of Madagascar crested ibis (which I did not see, nor did I see them signed anywhere).

- Chacoan peccaries were absent from their enclosure, with an "animal temporarily off display" sign in their place. They are still signed, however.

- There is a herd of ~6 impala out on the Africa Trail Savannah. I'm fairly certain they are signed as well.

- The orangutans appear to be having some minor alterations to their outside facilities. Unsure exactly what sort but the two individuals I saw appeared to be limited to their indoor quarters.

I didn't get a chance to ask anyone about hybrid ruffed lemurs @Coelacanth18, and the animals themselves were also not particularly cooperative considering the heat. When an opportunity presents itself I'll try and get an answer.

That's disappointing, there aren't a lot of zoos in the USA that hold them now.
 
A couple additional updates from another visit today:

- There seems to be some sort of trapping campaign going on with the zoo's black-tailed prairie dogs, as the exhibit that was bustling with 6 of them last weekend had only one today. Over the course of the day I also noticed first one, then a second live trap appear in the enclosure. I didn't get a chance to ask what was up, but it could very well just be they're being moved to make way for enclosure maintenance or renovations.

- Speaking of renovations, it seems like there is a good deal happening in and around the Arizona Trail aviary building. For starters, the Diversity in the Desert room has been closed for at least a week, so I expect something may be changing in there. Additionally, there is a small cinderblock structure taking shape near the Southeast door to the aviary building, right next to the current ferruginous pygmy owl enclosure. It looks like it's intended to be a new enclosure, and while I'm unsure what it may contain in the future construction seems to be progressing at a pretty good clip.

- A cool morning helped facilitate activity in the zoo's primates, allowing me to confirm that there are no hybrid ruffed lemurs present, answering Coelacanth's question. The zoo has two black-and-white ruffed lemurs and three red ruffed lemurs.

- Having a look at the most recent USDA inspection sheet (completed on July 21, 2025) confirms that Visayan warty pigs have indeed left the zoo but also suggests that Madagascar ibis still have a presence, with one listed individual. It's very possible I missed it in one of the many Tropical Flights aviaries, so I'll have to go back and scrutinize them more closely when I get a chance. Additionally, the USDA inspection sheet indicates there are three Kirk's dik-diks somewhere on the zoo's grounds. I suspect these are behind the scenes somewhere, as I don't have a clue how I could have missed them otherwise.

- Finally, while trying to figure out the names of the individual nyala bucks I saw today I ran into a bit of a puzzle. The zoo posted their names (Rye, Rusk and Biscuit) back when they acquired three of them back in 2021. However, they now only have two. I haven't been able to find any record of a death or transfer on the zoo's social media. Looking back at USDA inspection reports shows there were three nyala present in October 2024, but the most recent report lists only two, consistent with what I observed today. Does anyone know what happened to their third nyala? And which one it was?

I can finally upload images! Here's a picture I took this weekend of the in-progress exhibit construction going on near the Southeast door to the aviary building. The stone is new, as last weekend it was bare cinderblocks.

Interesting, those look like terrarium windows to me, the three smaller horizontal and two taller windows, similar to the snake area in the aviary.

Per this article, this construction is for air-conditioned reptile terrariums due to even their native desert heat getting to be too much to bear for them. There’s more information detailing the process and findings.
