African penguin Reproduction: Fertile Eggs


The process of candling eggs is an important part of our African penguin reproductive program at the Academy. It allows the staff to determine fertility early enough to predict hatching and plan for rearing chicks. Candling eggs was reviewed in the penguin 20 October 2010 blog post. Candling eggs requires a steady hand and experience as the embryo is developing important parts of their body every hour in the first few days. While candling we look for blood vessel development inside of the egg. The embryo develops an embryonic lung system that looks like an intricate network of blood vessels which allows the embryo to exchange gases through microscopic pores in the egg shell. The upper third of the egg above shows the characteristic vessels of development at day 9 of incubation.-Pamela Schaller

African penguin Reproduction: Burrow Cam


Our African penguins have successfully hatched out 108 chicks since 1983. As a participating member of the African penguin SSP (Species Survival Plan) http://www.aza.org/species-survival-plan-program/ , we have been able to watch many of these birds grow and move on to other facilities. We are a breeding facility and have recently been observing some of newer couples begin to nest. We will be experimenting with the biologist cam placement in one penguin burrow to observe penguin reproduction. The couple we are monitoring is “Agulhas” and “Jahzara”.  You can join us while we watch this first time couple try to set up a nest and pair bond. Penguin burrows can be constructed out of guano, sand, dirt or whatever is available in the wild. Our burrow is fiberglass and allows for both adult penguins and penguin chicks to nest. It also has an entrance to the exhibit. The camera will move inside of this burrow on occasion and will get coated with salt and leaves that the birds bring into their burrow. We hope that the camera view is minimally obstructed, but this may be possible at any time. -Pamela Schaller
