Life-span[edit]

What is their life span? I would really appreciate the feed-back. - Cameron

Life span estimates are not available. As far as I know there are no ongoing long-term banding and monitoring schemes of any Rockhopper population. A rough estimate can only derive from other penguin species that are monitored in the wild (i.e. Little penguins, Yellow-eyed penguin). And those species can live up to 20-25 years. However, the majority of birds does not reach that age, mainly because they get killed/get eaten/starve to death etc. So a good average age for a penguin is somewhere between 10 and 15 years I should think.

New photo?[edit]

Hey, I took a photo of a rockhopper recently that I was pretty happy with. It might be good for illustrating their facial features more closely in the article, or their pretty red eyes. Whatever goes!

Foraging Behavior[edit]

Hello, I am thinking of adding to this page concerning the foraging behavior of these penguins. Here are my references. Biliken 1995 (talk) 18:39, 1 December 2015 (UTC)[reply]

Peer Reviews[edit]

Hello Biliken 1995,

I've revised some of your contributions to Foraging Behavior to be a bit more concise and neutral. Your research contributions provide insightful and relevant information to the Southern Rockhopper Penguin's foraging behavior and influence of geography on foraging. I've also looked through your sources and they are solid and thorough in coverage. You have addressed the evolutionary aspect of foraging behavior in your contributions well also. I think from this point you can proceed on to making the coverage of the main experiment more concise and straightforward to make the conclusions mentioned at the end more clear. Also, I did not think the segment regarding the bees was relevant enough to E. chrysocome to be included in the Foraging Behavior section (although I do understand your intentions). Looking forward to seeing the progress of this article!

Hi Biliken1995,

Overall, your post on foraging behavior of rockhopper penguin is well written. The sources you cited are very informative and critical for the sub-topic of your contribution. A summary of the articles about a relationship between foraging behavior of rockhopper penguin and a geological factor was very interesting. But, there was a part where I was bit confused about diving and chick growth, so I made minute change about efficiency of diving. To me, adding few words there made the whole sentence more clear. Overall, it was great and I look forward to see your final draft.

Anon2831 and Random6251,

Thank you for your helpful and insightful comments. I have deleted the section about the honey bee experiment, as I see where it does not directly apply to my topic. As well I summarized the experiments rather than referencing them. I took the main points of the experiments and applied them to foraging behavior in these penguins. I also deleted the section on carbon isotopes because it did not seem relevant to my overall topic. Over the whole article I added and changed some wording for better understanding. As for the conclusion, I tried to make a more concise ending to my article. I kept and edited the last paragraph on climate change as it helps the reader relate this topic to a popular topic in the news. Thanks again!

Hello Biliken 1995!

I thoroughly enjoyed reading you article about foraging behavior and how different climates can have such great effects on the survival and behavior of this species of penguin. I was a bit confused about the relationship between chick growth and other environmental factors such as food load and dive depth. I know that it is unadvisable to cite specific studies in wikipedia articles, but I was wondering if this was just a general trend you observed in your research or if you found stats on the actual amount chick growth was affected. Perhaps additional sources that explain the prevalence of similar behaviors and trends could be beneficial? I really liked your insight into the evolutionary changes in climate that could impact E. chrysocome. I made some minor edits with grammar and wording, but I think the content you have is already quite substantial and edited well.

Hi Billiken 1995!

Your addition is very thorough and goes in to discuss multiple traits of these penguins. However, you I feel that you could talk a little more on the evolutionary origins of this variation such as if it is simply a trade off or if it is a form of plasticity. Also, you could relate or explain how the various pressures or accessibility of food leads to the differences in foraging behaviour. Otherwise, your sentence structure is good and conveys the points you make well. I've only changed the wording in some sentences and certain terms you used so as to make it flow a bit more easily.

Hello Honey4bees and Biol&steel!

Thank you for your helpful comments. I decided that the chick growth was not relevant to foraging behavior, so I deleted that section. Thank you for voicing your confusion. I edited some of my paragraphs as to make the article more clear and easy to understand. I talked more about plasticity, as recommended. As well, I explained how accessibility to food shaped the penguins' foraging behavior.

Biliken 1995 (talk) 18:39, 1 December 2015 (UTC)[reply]

Hello Evol&Glass,

Thank you for your insightful comments and edits. I changed some of my wording and took your advice about adding together the paragraphs and deleting unnecessary details. I made my article easier to follow and understand by giving the reader the overall/main point of my sources. I talked more about plasticity instead of favoring a foraging behavior; I think this will help the reader see the species’ ability to be flexible, instead of focusing on which environment would be most suitable. My main changes were to the middle paragraphs, as recommended, I added and changed some things to better suit the flow and content of the article.
