The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. Adult males begin to come ashore at the breeding grounds in the spring (September) but do not start to compete for territories until the beginning of summer (November) (striling, 1970). One report of 60,000 skins from Antipodes islands in 1804-05 was surpoassed by a report in 1814-15 of 400,000 skins being taken over the two-year period (Taylor, 1992). The pups start to eat solid foods just before weaning. There are now established and expanding colonies around the entire South Island, on Stewart Island and all of the New Zealand subantarctic islands. Some articles contain sponsored content; where I have accepted such content, received an item free of charge to review or been hosted on a trip, this has been stated in the article. This delight is available during the period between April and October. Juveniles ate. Wilslife Research 22: 201-15. paper whether the disrupted behaviour was at breeding or non-breeding colonies. Most mothers were quiet for the first hour after birth, whereas most pups were very active, looking around, sniffing and nuzzling their mothers and sniffing the rocks. Once together, females use olfactory recognition to confirm the pup as their own. Arctocephalus forsteri. Don’t forget to follow me on social media to keep up to date with my recent posts, adventures and thoughts. However, females intent on returning to the sea usually manage to escape when the male's attention is directed elsewhere! In the spring juvenile fur seals disperse from the creche. The smaller seal responded defensively with the open-mouth display, and after a little more posturning, both youngsters went back to sleep a short distance apart. and Fletcher, L. 1988.

[1] Often females mate only once a year, and this usually occurs eight days postpartum for about 13 minutes on average. [18] Several regurgitations by sea lions have been found to contain remains of fur seal pups, some with plastic tags previously attached to female fur seal pups.[18]. In Croxhall, J.P. and Gentry, R.L. Status, biology and ecology of fur seals. During December and January (i.e. New Zealand Journal of Marine and Freshwater Research 29: 223-234. These animals are opportunistic foragers, preying on several different cephalopods and fish, as well as birds, such as shearwaters and penguins. Pups are dark brown with silvery-grey fur on the head and neck. [12], Females mature between 4 and 6 years old, and males mature between 8 and 10 years old. Non-breeding animals are also known from New South Wales, Queensland and New Caledonia. They are in the family Ortariidae, which is the family of ‘eared seals’. New Zealand fur seals (Arctocephalus forsteri, or kekeno) are found around New Zealand and its offshore islands, and southern Australia. New Zealand fur seals' prey stay very deep underwater during the day, and then come closer to the surface at night. Most dives were less than 10m and average dive duration was 23 sec. New Zealand Fur Seal Wikipedia article -, 2. Canadian Journal of Zoology 83: 1149-1161. Males typically forage over continental shelf breaks in deeper water, while females typically utilise the continental shelf as foraging grounds. My passion for travel led me to start up this blog, partly to record my adventures and partly to inspire others to travel. Juveniles have been located at more than 1000 km from where they were born. There were also other people at Aramoana Point and Allen's beach, and all people we saw behaved with great respect towards the seals. The pups need to progressively develop nocturnal diving skills while they still have their mothers' milk to fall back on if dives are unsuccessful. Immediately after birth the mother begins frequently sniffing the newborn pup to better identify when she has to find it after a trip out to sea. However, it was not clear from the Boren et al. Mothers often went to the sea briefly to immerse themselves in water, and then returned to their pups according to a specific location in the colony. Doing this may help them develop skills for foraging, and for anti-predator and social behavior. A study in southern Australia investigated possible competition for prey between adult males of the NZ and Australian species as well as among juveniles, females and males of the NZ fur seal (Page et al., 2005b, 2006). There are no breeding colonies in the North Island, but these seals do occur on the Three Kings Islands in the north, off the northernmost tip of New Zealand. Image: [5], So called "Upland Seals" once found on Antipodes Islands and Macquarie Island have been claimed as a distinct subspecies with thicker furs by scientists although it is unclear whether these seals were genetically distinct. This behavior is easily recognized from observing a seal colony. Three types of seal breed in New Zealand: fur seals, sea lions and elephant seals. & Goldsworthy, S.D. 2004. Journal of Mammalogy 88: 639-648. After the arrival of humans in New Zealand, and particularly after the arrival of Europeans in Australia and New Zealand, hunting reduced the population near to extinction. when the pups were very young) the females came ashore for ~4.3 days at a time, but this reduced to ~1.8 days from February to November (i.e. & Goldsworthy, S.D. The New Zealand fur seal was historically hunted to local extinction, first by the Polynesian settlers to New Zealand and then even more thoroughly by European hunters in the 19th century. Females forage further offshore in Autumn, but inshore again in winter (Harcourt et al., 2002). [8] They are also known to have been shot by commercial and recreational fishermen, because they are assumed to interfere with fishing gear. Leopard seals also visit. Several calls between mother and her rightful pup may be exchanged before mother and pup nose each other - the pup usually with evident excitement. A New Zealand fur seal is an excellent swimmer. In South Australia it is estimated that nearly 1,500 seals die from entanglement every year in debris such as loops or packing tape and trawl net fragments. [1] They can dive deeper and longer than any other fur seal. These sites can get noisy. Estimation of fur seal bycatch in New Zealand trawl fisheries, 2002-03 to 2007-08. The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. The Australian Commonwealth Government has jurisdiction from three miles offshore throughout the rest of the countries’ 200 mile EEZ. New Zealand fur seals are Polygamous, this means that males mate with as many females as he can! The physical appearance of fur seals varies with individual species, but the main characteristics remain constant. The species is in the sub-order pinnipedia, which roughly means ‘flippered feet’. There are now healthy populations around the Otago Peninsula. Photos: Sue Wilson. Pups are 3.3–3.9 kg on average, and between 40 and 55 cm long. Pups go upstream from the beach, play in the pool at the base of the waterfall and also climb up the rocks into the forest to explore. The females ate mainly arrow squid in summer and autumn, but preferred an inshore benthic fish (the ahuru) in winter (Harcourt et al., 2002). When the females return they only feed their own pups, and have been seen to be hostile toward pups that are not their own. It is known that there is significant mortality of NZ fur seals in commercial trawl fisheries, particularly in the hoki (inshore) fishery, with few seals being reported caught in deepwater or scampi fisheries. [14] Suckling can occur for about 300 days. [1] Monitoring of these pinnipeds in the Kaikoura region found that entanglements with green trawl nets and plastic strapping tape were the most common. They are excellent swimmers, and pups, once weaned, will sometimes cover great distances.

[5] They have a pointy nose with long pale whiskers. Females are metallic on the back; paler underneath with a brown belly. Adult females' diet tended to be generalist, dictated by prey abundance and the time constraints of being away from their dependent pups.
