Condor Chick: Nest Barrier

One of my favorite sayings is “boring is good.” When things are boring, everything is going according to plan; excitement is often the result of something going awry. As many Condor Cam viewers have experienced, the rearing process for a California condor can be long and slow—some may even say boring. It makes sense, though, for a condor to develop so slowly; she has lots of growing to do! When our chick, Cuyamaca, hatched, she weighed approximately 6.3 ounces (180 grams). When she reaches her fledge weight of 17 pounds (8 kilograms) or more, she will have increased her hatch weight by 44 times! I, myself, have only increased my birth weight by 19 times.

On July 15, at 112 days of age, Cuyamaca took her most recent step toward leaving the nest: she jumped up onto the barrier between her nest box and the adjoining roost area. She quickly hopped back into her nest, but that’s okay. There’s no hurry to fledge, or leave the nest, just yet. Her feathers still need time to fill in. In the meantime, hopping up and down from the barrier will exercise her muscles and improve her balance. Any day now, she will hop into the roost area on the other side of the barrier. Here, she can look into the flight pen where her parents, Sisquoc and Shatash, are. She also will be able to warm herself in the sun, if she so chooses.

The next step of Cuyamaca’s development will be to fledge. When she is ready, she will jump off of the 8-foot-tall (2.4 meters) nest ledge. She will either slow her fall to the ground below the ledge or fly to a nearby perch. We consider her fledged when she can get up on a perch by herself. The youngest we have seen a condor chick fledge here at the San Diego Zoo Safari Park is 123 days old. Sometimes chicks have waited until over 165 days. It all depends on the chick.

The parents tend to be very vigilant at this phase of their chick’s development. It could appear over-protective to us, but keep in mind that they have invested an entire breeding season and lots of energy into this one chick. It benefits them greatly to make sure that their sole offspring is safe, healthy, and strong. They usually don’t coax or pressure their chick to leave the nest; on the contrary, we have seen parents make sure their chick doesn’t stray too far from the nest if it’s not ready yet. The parents will usually perch and/or roost near the fledgling. They also will join her when she finally starts going to the feeding area of the flight pen. Most of the time, though, they will push her aside and eat first, feeding her when they are done. In condor culture, the bigger, more dominant birds usually eat first while the subordinate birds wait their turn. The earlier Cuyamaca learns this from her parents, the better she will assimilate into a wild population after she is released. Don’t worry—Sisquoc and Shatash won’t let Cuyamaca starve! They will continue to feed her even when she is out in the flight pen. Eventually, she will eat more and more on her own.

Depending on Cuyamaca’s development and activity levels, we will try to switch the Condor Cam view from the nest box/roost area to the flight pen. You’ll be able to see the roost area, most of the perches in the pen, the feeding area, shade areas created by plants, and the pool, where she can either drink on her own or bathe (one of my favorite condor activities to observe!). The view will be wide, so detail will be harder to discern. Also, we do minimal maintenance in the pen once the chick is large enough to look over the nest box barrier, so the pen has lots of plant growth and dried food (animal carcasses) in it. We limit our activities in/near chick pens so as not to expose the chick to humans, thus desensitizing her to our presence. We have found that chicks raised in isolation from humans tend to be more successful once they are released to the wild. The flight pen won’t look as nice as an exhibit you might see at the Zoo or the Safari Park, but Sisquoc and Shatash prefer it that way if it means we stay away from their precious chick!

Thanks so much to all of our faithful and dedicated Condor Cam viewers. Soon, your support and devotion will be rewarded when our “little big girl” spreads her wings and takes that next step. Rest assured, though, that Cuyamaca’s story will be far from over!

  1. In the roost area this morning!

  2. Thanks for the update. I look forward to watching her, hopefully, on the Condor Cam view of the flight pen.

  3. Thank you Ron for today’s up date. It’s very exciting to see what is next for Cuyamaca .

  4. Hi! Got on the condorcam to see Cuya, and the cam is not showing Cuya in the nest box! It’s showing a grey wall and a little spider on a part of a web! Can you please get the cam back on Cuya? Wanted to see how she’s doing!
    I did get on the cam last week, and she was on the barrier having a little tussle with one of her parents sitting on the roost bar. They were having a beak fight with each other! Cuya is looking real good, still has some of those down feathers on her wings, and she’s a very relaxed kid right now. I wonder if she’s been able to tear into her food by herself when mom or dad brings something to her? I think she’s old enough to start to do that by now. Let us know about the cam, and keep us updated about Cuya, ok? Thanks!

  5. Got back on the condorcam, and it’s back on the nest box! YAAY!! Just saw Cuya on the barrier, and she’s doing very good with her balance on the barrier. Right now, she’s just looking around enjoying some nice fresh air. Thanks for getting the cam straightened out!

  6. Thanks Ron for the informative post.
    I have not followed Cuya as carefully as with Saticoy but I wonder if she pecks less at her parents? (anyone’s observations welcome)

    • Cuya has had her times giving her mom and dad some pecks on them when they are sitting close to each other. I watched Cuya, sitting on the barrier, and her mom, Shatash, sitting on the roost bar, having a pecking session at each other a few days ago, and they were having their fun at it!

    Oh what a darling baby, I noticed that Dad seems to be the one to nurture, feed, and hang with little
    Cuya, is this typical of the male Condor, rather than the female?? I find this behavior fascinating, wonder
    what my Life would have been like if Dad had been the one to feed, clothe, and hang with us while we were
    growing up, instead of working so hard for Us. Thank You for letting us peek at this BABY!!

    • Hi Cynthia, Sisquoc seems to be a very active parent. I noticed this with Saticoy as well. It’s great when dads are so involved with their children, isn’t it? I don’t know if this is normal for condors or if Sisquoc is just an exceptional dad.

  8. Great camera work today guys! Lot’s of good family moments…thanks

  9. Thank you or the update! So exciting to see her all the way onto the roost.

  10. Thanks again for a wonderful experience again this year!

    Is there any possibility of a “split-screen” view with both the nest and pen cameras?

    Thanks Again!!

    Monitor’s note: That would be wonderful, but we don’t have the budget to do that at this time.

  11. Cuyamaca is being groomed by her mother and she doesn’t seem to like it one bit, just like some human children. So funny and so cute!

  12. Just got on the condorcam, and there was Cuya out of her nest box and standing in the gravel area in front of the box! It looks like her leg and wing strength are strong enough for her to get to that landing spot right now. I’m sure that she can get back in her nest box without any problems now. She’s looking pretty good at 4 months old!

  13. It’s hard to believe that Cuyamaca is about to join her parents in the large pen. It seems like it was just yesterday that she was that little ball of grey feathers! So much fun to watch.

  14. Just saw Cuyamaca jump from the nest ledge to the roost ledge. Is she about to try to fly now? If she does will you let us know?

  15. Hope everything ok with Cuyamaca . Camera is off

  16. What fun to see the condors in there home . has Cuyamaca taken flight yet ?I am so excited to see this next part of Cuyamaca growing up thank you ( Thr team).

  17. Oh my goodness Cuyamaca is out with mum and Dad amazing

  18. DID I MISS IT? Is she officially fledged? All I see is the larger compound. Is that the nest/roost in the background?

    How exciting!

  19. Oh, my goodmess! The camera is out in the yard. I think I can see Cuyamaca out there. Congratulations, little girl!

  20. Now Cuyamaca is out in the pen ,will she return to the nest to sleep or stay out side now?
