The northern rockhopper penguin (Eudyptes moseleyi), also known as Moseley's rockhopper penguin, Moseley's penguin, or Tristan penguin, is a penguin species native to the southern Indian and Atlantic Oceans. It was formerly considered conspecific with the eastern and western rockhopper penguins.
A study published in 2009 showed that the population of the northern rockhopper had declined by 90% since the 1950s. For this reason, the northern rockhopper penguin is classified as endangered. The rockhopper penguins have been considered to consist of two species, northern and southern rockhopper penguin, since research published in 2006 demonstrated morphological, vocal, and genetic differences between the two populations. The latter species was itself later split into the eastern rockhopper penguin and the western rockhopper penguin. Molecular datings suggest that the genetic divergence between the northern and the two southern species of rockhopper penguin may have been caused by a vicariant event caused by a shift in the position of the Subtropical Front during the mid-Pleistocene climate transition.

Rare
Under 5% of wildlife watchers report a Northern Rockhopper Penguin sighting in Falkland Islands on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 66th most-seen of the 79 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Northern Rockhopper Penguin in Falkland Islands on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Northern Rockhopper Penguin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Falkland Islands, in our data
Falkland Islands is the only park on Wallace's Line with enough records to rate Northern Rockhopper Penguin sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Eudyptes
The closest relatives of the Northern Rockhopper Penguin that you can see in Falkland Islands (genus Eudyptes, Crested Penguins) are Southern Rockhopper Penguin (about 40%) and Macaroni Penguin (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Northern Rockhopper Penguin is recorded against all the birds logged in Falkland Islands (18 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
