Our newest California condor chick hatched at 1:33 a.m. on May 17, 2019. Although it hatched in darkness, and you weren’t able to see it happening on Condor Cam, proud and protective parents Siwon and Sola are doing a terrific job, and the chick looks great!

Both the male and female California condor provide care for the chick. This drive is very strong, and it’s not uncommon to see the parents vying for time with the chick, especially immediately after hatching. This happens in the form of leaning into each other, pushing one’s way onto the chick; scooping the chick from one parent to the other; or nipping at neck skin or tugging at feathers to get the other parent to move. As time passes after hatch, they settle into a routine and the nest exchanges become much calmer.

The chick weighed around 6.3 ounces (180 grams) at hatch. The hatching process can be grueling, so afterward, the chick usually rests a lot and is brooded – or sat on – by the parents. We often call this “sitting tight.” The parents are providing protection and warmth, especially while the newly-hatched chick is drying off. With the chick being weak and wobbly, it often is hard to feed, but that is okay—it’s still getting nutrients from the yolk sac that it absorbed into its belly just before hatching. After about a day, the chick can hold its head steady and the parents then start providing food.

The parents eat food that we offer out in the flight pen, and then bring it to the chick in their crop (a bulge in their esophagus where they can store up to three pounds of food). The food is regurgitated for the chick, providing a warm and nutritious meal. Mmmmmmm! The diet we provide varies, depending on the day, but it can include rabbits, rats, trout, beef spleen, and ground meat.

While the chick is very young, it is often difficult to witness a feeding, since the parents are standing directly above the chick, usually blocking the camera view. If you see the parents slightly bobbing their heads while standing over the chick, feeding is occurring. Feeding sessions are fairly short for very young chicks, since the crop at this age is only about the size of a lima bean.

Sometimes viewers are concerned about the number of times that the chick gets stepped on by the parents. In many species, ranging from hummingbirds to elephants, babies get slightly squished by the parents. Usually, it’s just a minor misstep and the baby will let the parent know with a brief vocalization. Condors are no different or no more fragile. They are very hearty little chicks!

As young as four days of age, we have seen chicks sifting through the sand in the nest, picking up items on their own. We’ve even seen chicks swallowing small pieces of its eggshell for dietary calcium.

At the end of the condor chick’s first week of life it weighs around 10.58 ounces (300 grams). It is getting much stronger, but is not venturing around the nest very much yet. Coordination is improving and we can witness social interactions with the parents: nibbling, preening, and nuzzling. Every once in a while, you may see the chick quivering almost like it has the hiccups. It is actually vocalizing. Condors don’t have a true voice box, or “syrinx,” like other birds, but they can make crude, primitive vocalizations. Adults may grunt, wheeze, or hiss. The chick can make a high-pitched, scraping squawk, usually when it is begging or has been out from under the parents for too long.

The next few weeks of development are very exciting, not just for the condor family, but for all of us watching on Condor Cam. Stay tuned!
