also aligning with the land viewing for the Chinstrap Penguin (Pygoscelis antarcticus). Their exhibit alone is around 3.6 acres in total. In order to provide the most natural exhibit possible, deep analysis and research is required. Based on habitat, geographical location and environmental preferences, we designed a penguin habitat featuring ice, snow, coastal rocks, accurate air temperature and natural underwater range
A 3.6 acre exhibit, while nice from a realistic point of view, will be exorbitantly expensive to chill both the air and the water to the required temperatures. There is a reason subantarctic penguins are primarily centered at large and well off institutions. Also, per the AZA standards 15 Chinstraps only require 135 square feet of space. This is roughly 11x12 feet.
the exhibits can get to as low as -4 degrees fahrenheit, or -20 degrees celsius.
This is not within the recommended parameters for Chinstraps - minimum recommended temperature is 24F. Seawater begins to freeze at 28.4F so -4 and you might start having issues with ice. Remember Chinstraps move north onto the open ocean in winter where it stays notably warmer.
zoo is home to 5 male chinstrap penguins and 10 female chinstrap penguins.
It is recommended for mixed sex flocks to be close to an even sex ratio, as during the breeding season unpaired birds often cause aggression by attempting to steal mates, nesting material, or just picking a fight.
During the fishing season, males and females may alternate between the off-display habitat to provide a more realistic approach to how chinstrap penguins live outside of zoos and aquariums.
Given there are no external differences between sexes, what exactly is the point here? Also removal of birds from the colony during the breeding season has been reported to cause stress and depression in mates. Aggression can also arise from it if a dominant bird is removed.
I think if I were to add any of those species, it would be gentoos. However, chinstraps are known for being an aggressive species, and I’m not sure what species they have been mixed with in other zoos.
All penguins are generally aggressive. Chinstraps have been successfully mixed with many of the other subantarctics without any real problems. I've seen them with Emperor, King, Gentoo, Adelie, Rockhoppers, and the Macaroni.
As for Adelies, I feel that their captive requirements are too hard to meet for a brand new zoo, but it’s good speculation.
Your exhibit already exceeds the requirements for Adelie, and they are fairly similar in range to the Chinstrap. There is very little difference between keeping the two. Quite frankly this penguin house would sink most small zoos just on sheer cost of cooling it.
