    Restricting penguins instead of people: a mitigation of the impact of uncontrolled visitors on yellow-eyed penguins

    ​Abstract
    ​Katiki Point is a c.10ha reserve at North Otago, South Island, New Zealand, jointly administered by the Department of Conservation (DOC) and Ngai Tahu, indigenous owners of most of the reserve. This headland had unrestricted public access and no penguins when founders of Penguin Rescue began conservation management of local seabirds in 1982. We created a breeding colony of yellow-eyed penguins (Megadyptes antipodes) initiated by rehabilitated birds in 1991. Nest numbers have risen and fluctuated from an initial two nests to a peak of 34 nests in 2014, finishing with 23 nests in 2018 at an overall deterministic average annual increase of 9% through 28 years. Visitor numbers exceeded 10,000 annually through the last decade, an influx attributable to accolades in TripAdvisor extoling free close-up viewing of penguins. A substantial impact was first recorded in 2014 with a drastic reduction in penguin breeding success. This affected pairs with nests or with access routes from the sea within 10m of visitor paths.  Following a DOC recommendation an internal fence was built reducing the proximity of people to penguin that decreased the available breeding habitat for penguins by c.40%. The administrators of the reserve further mitigated disturbance by realigning public paths away from most nests and by closing access overnight. However, the impacts persist and require ongoing mitigation, an unacceptable outcome for the future of this colony that accounts for 10% of the South Island population. Here an endangered species has been compromised in favour of free public viewing.

    Numbers of yellow-eyed penguins (Megadyptes antipodes) are decreasing at south-eastern South Island, New Zealand, with a high risk of extirpation within decades. Published records for annual nest numbers 1982−2015 showed large fluctuations; beginning at 453, peaking at 642 in 1996 and ending at 256 nests. This equated to an overall deterministic average annual decrease of 2% through the 34 years. Intensive management at Moeraki, North Otago, by Penguin Rescue through the same period began at six nests (1% total), peaked at 58 in 2013 and 2014 and ended at 46 nests (18% total), at an overall deterministic average annual increase of 6%. Rehabilitation of compromised penguins began at Moeraki in 1984. We will calculate the minimum impact of rehabilitation on the Moeraki population in 2018 not only by subtracting any breeding that followed rehabilitation of marked female juveniles or adults but also by subtracting any breeding by their female descendants. Just now we have comprehensive results only to 2006, by which time 14 females nested at Moeraki after rehabilitation (and another four nested elsewhere). The 43 nests at Moeraki in 2006 included six (14%) rehabilitated marked females and seven of their female descendants: their subtraction reduced number of nests by 30% to 30 nests. Techniques have evolved throughout the rehabilitation process and will be expressed as increases in female breeder survival and increased female recruitment; e.g. through the most recent four years, an average 53% of female breeders and a total 60% of female recruits had been previously rehabilitated.

    ​Prey switching by yellow-eyed penguins attributable to recreational over-fishing?

    Blue cod (Parapercis colias) is the most important marine recreational fishing species around South Island, New Zealand. It accounts for 63% of the recreational catch at North Otago where published surveys found increases in undersized cod caught (16–30cm), 50% in 2005 and 41% in 2011. Increased abundance of small cod was attributed to fishing pressure. Previous diet studies on yellow-eyed penguins (Megadyptes antipodes) 40–50km further south at Otago Peninsula found blue cod numerically accounted for 1% of prey in 1984–86 and 2% of prey in 1991–94 from flushed stomachs, and 24% in 2016 from penguin-borne cameras. The likelihood of an increased importance of blue cod in the penguin diet through time is further supported at Moeraki, North Otago, where 159 cod (average=21cm, range=8–31cm) accounted for 48% of prey represented in 83% of 47 adult casts in the 2014 season. Timing of the prey switch to blue cod was deduced from analysis of the contents of food spilt when adults feed chicks. We systematically collected spills from Otago Peninsula through 16 seasons, 1997–2012, then from Moeraki through five seasons, 2014–2018. Blue cod remains occurred in 66% of 290 spills, with calculated length remaining similar through time (262 fish, average=22cm, range=9–30cm). A logistic model indicated increase in average occurrence of cod in spills from 29% in 1997 to an asymptote of 69% since 2006. Implications of this prey switch extend beyond penguin biology to include fisheries interactions and penguins as a pariah for fishers.

  • A paucity of females – predicting a continued decline in yellow-eyed penguins
     Hiltrun Ratz, Chris Lalas, Rosalie Goldsworthy
     
    Abstract
    Yellow-eyed penguins, Megadyptes antipodes, are listed in the IUCN Red List as endangered and their numbers have declined in the three key mainland breeding sites through the last four years: Moeraki, (North Otago), Boulder Beach (Otago Peninsula) and Long Point (Catlins). We compared the demography of resident yellow-eyed penguins at Moeraki in 2015/16 with that presented from 10 years of data by L. E. Richdale in A population study of penguins (1957). The key indications of a decline in a population is that the proportion of the population breeding increases as recruitment decreases, and the proportion of females decreases due to a sex-bias in survival. Breeders represented 71% of the resident population at Moeraki compared with 61% in Richdale’s study. Females available for recruitment accounted for 5% of the population at Moeraki, less than half the 11% reported by Richdale. Without a more substantial reservoir of females available for recruitment there will be no fast recovery of the population. Application of average values for survival and recruitment predict a 2% annual increase in nest numbers from the demography generated by Richdale but a 9% annual decrease from the recent demography at Moeraki. We also predict a decrease in breeding success due to increasing interference by surplus males. These predictions are possible only because the Moeraki population is marked and closely monitored throughout the breeding season and subsequent moult.

    The ODT featured an article on 11 March 2017 about  juvenile yellow-eyed penguins returning for their annual moult: hope for the future of the colony with some of these 1-year olds hopefully starting to breed in 6 months time.
    ​A second article on the same day talked about the problems that a surplus of adult males can cause in a colony.
