When the Dan and Vi McKinney Penguin Habitat opened in Conrad Prebys Africa Rocks three years ago, if you had asked me to predict where we would be today, I never would have guessed. At that time, we had just finished construction on the largest saltwater penguin pool in the US, and our small colony of 20 birds (mostly youngsters still in their blue plumage) were finishing their quarantine period. Now, 3 years later, our colony has grown to 36 birds; and those “little blue youngsters” have reached maturity and have begun creating the first generation of hatches here in San Diego.

We opened our nest boxes for the season in August of 2019. During the breeding season, penguins form pairs—and sometimes break up and re-form again. That’s only the first decision they have to make. Next, they’ll choose a nest, decide they don’t want that one, and take the one next door. Then they decide to move back to the first one…or a different one.
We have 14 nest boxes available to the group, and a few of those are highly prized, resulting in competition among the birds (just like in their native habitat). There is more drama in the colony than on reality TV! Only the heartiest boys will get a prime nesting spot.
After the eggs are laid and about 10 days old, we candle them—shining a bright light through the shell to see the structures inside, to determine fertility. Earlier this year, we were excited to see that two eggs (under different pairs) were showing great development at that point. We kept our fingers crossed that the parents would incubate each egg as they should and a healthy chick would emerge from the shell.

One of the eggs belonged to Scott and Tinka, a newer pair with no breeding history. The other egg was under Jack and Lori, another pair with no breeding experience (fun fact: Lori and Tinka are sisters!). All four of these birds were still in their juvenile plumage when they arrived in San Diego. Scott and Tinka proved themselves to be great parents, dividing duties as if they had read the textbook on it. Sadly, Jack and Lori didn’t check out that same book…

With video monitors in all of the nest boxes, we are able to see exactly what is happening with eggs or chicks without having to disturb the pairs. Scott and Tinka’s egg hatched right on time, and we watched the parents do an excellent job the first few days. Jack and Lori’s egg hatched four days later, and we were not comfortable with what we were seeing. Those first days are very important—they tell us how attentive the parents are or if only one parent is doing all of the work. After 24 hours of observation, the decision was made to remove the second chick from Jack and Lori, and place it for fostering with an experienced pair, Danny and Malloy. They did a terrific job raising Doug as first-time parents last season. Danny and Malloy accepted the chick quickly and easily, and did an outstanding job raising him.

When the chicks were 19 and 22 days old, we removed them from the parents (which we do with all of the chicks we raise) so they would become comfortable around people, and learn to hand-feed from us. It took a few days for them to understand that they would now be getting fish pieces fed through our fingers, and we would not be regurgitating fish to them ourselves (whew!). They were smart little babies and figured out pretty quickly how the new feeding system would work. They both had great appetites and grew quickly to their full adult size.

Just a bit shy of three months old, they are self-sufficient, independent kids. They spend their days enjoying their pool and practicing their swimming skills. They have almost lost the last tiny tufts of down on their heads and will be ready to meet the rest of the colony in the coming days.
World Penguin Day is Saturday, April 25, 2020. Yet, there’s so much to discover about these birds that we’re having a virtual celebration from April 24 to 26. Visit this web page of activities, and have fun joining us in honoring penguins.

Good evening San Diago Zoo! What a fantastic place you have. I am so pleased to have found you. I look forward to following your animals and birds. Exploring will be something to fill my Christmas!
Will the Penguin section of the San Diego Zoo be open on August 11, 13, or 14, 2020?
Blog Monitor’s note: It is open now, and I’m not aware of any reason it won’t continue to be.
Hi-
Do you have any new baby animals??????
Blog Monitor’s note: Yes! You can see some of them in these videos.
Hello I am a fellow 3rd grader learning about penguins! I have been asking are penguins good for pets?
Blog Monitor’s note: No, they would not be good pets—wild animals in general don’t make good pets. It can be hard to feed them properly (where would you get all the fish?) and their behaviors don’t match up well to what most people want in a pet (being cuddly, playing with humans, etc.).
Thank you so much for taking care of your animals even though COVID-19!
Thank you for still taking care of the animals even though COVID-19!
How much time do penguins spend in water?
Thank you to you (Debbie), the rest of the Keepers, and the volunteers who continue to keep this going.
I saw the chicks last week for the first time as they were out by the pool (I’m a consultant, work from home, and my other laptop has the penguincam up throughout my day). It was good to see one of them struggling to try to get out and mingle and to see Doug (he’s my favorite and I’m totally invested in his journey lol) totally curious about the new babies.
Please keep up the amazing work that you’re doing. The fiance and I can’t wait to come back to San Diego and see all the penguins again.
