  • A Rockhopper X Royal Penguin Hybrid from Macquarie Island
    VOL. 11 (2) JUNE 1985 35 AUSTRALlAN BIRD WATCHER 1985. II. 35-45 A Rockhopper x Royal Penguin Hybrid from Macquarie Island By KN.G. SIMPSON, Science Department, Victoria College - Burwood Campus, Burwood, Victoria 3125* Summary A specimen of Eudyptes penguin (Spheniscidae: Aves) originally collected in 1957 from North Head, Macquarie Island, after being identified as a Snares Penguin Eudyptes robustus Oliver 1953, has been re-identified as a hybrid between the Rockhopper Penguin E. chrysocome filholi Hutton 1878 and the Royal Penguin E. chrysolophus schlege/i Finsch 1876. Some facial identification features are discussed. Introduction AEudyptes penguin skin in the collections of the Museum of Victoria (MV) has a somewhat chequered history of identification and is festooned with labels and amendment tags. B7313, an adult female, was originally M/57 /B/111 collected by M. P. Hines under the auspices of Australian National Antarctic Research Expeditions (ANARE) on 3 November 1957, in the North Head Rockhopper/Royal Penguin colony, Macquarie Island. It was identified in the field as a Snares Penguin Eudyptes robustus. Another penguin of generally similar appearance, MY B7312, was also collected during 1957. B7313 certainly (possibly B7312 as well), was submitted to the late Dr (Sir) R. A Falla in New Zealand for confirmation of identification, and published by Keith & Hines (1958). B7312, collected on 17 March 1957 after completing its moult, does meet all of the identifiable characters of E. robustus and I accept it as such. One earlier record of Snares Penguin at Macquarie Island was on 5 February 1950 [Gwynn (1953) - see his plate facing p.

Bird species recorded breeding on the Snares Is for the first time since 1982 were southern black-browed albatross (Diomedea melanophtys), Chatham Island albatross (D. eremita), mallard (Anasplatyrhynchos), southern black-backed gull (Larus dominicanus), fantail (Rhipidura Juliginosa), and starling (Sturnus vulyaris). Fantails are now abundant on the Snares Is. Published work on the breeding chronology and breeding success of 8 intensively studied species is summarised, and new information on breeding ecology is presented for all breeding species. Sighting of 70 non-breeding and vagrant species are summarised;34 of these were new records from the Snares Is since 1980.

We examined the degree of sexual size dimorphism of adult birds across the species’ breeding range in the Atlantic Ocean and developed discriminant functions (DF) to predict individuals’ sex using morphometric measurements. We found significant site-specific differences in both bill length and bill depth, with males being the larger sex on each island. Across all islands, bill length contri - buted 78% to dissimilarity between sexes. Penguins on Gough Island had significantly longer bills, whilst those from Tristan da Cunha had the deepest. Island-specific DFs correctly classified 82−94% of individuals, and all functions performed significantly better than chance.

Foraging patterns of polar penguins. In: Adams, N.J. & Slotow, R.H. (eds) Proc. 22 Int. Ornithol. Congr., Durban: 2021-2039. Johannesburg: BirdLife South Africa. Sub-antarctic and polar penguins have revealed important differences in the distances travelled to foraging areas, the physical and biological characteristics of foraging areas, and foraging patterns. Differences are associated with preferred prey and its abundance. Data were acquired using satellite transmitters and time/depth recorders, the former giving location and rates of travel, the latter diving depths and patterns. Distinctions between travel and feeding dives help to assess foraging success. Data were matched to satellite imagery for determination of sea surface conditions. Sub-antarctic penguins travel further than polar penguins, feed near the Antarctic polar front, and are primarily diurnal feeders. Polar species feed at edges of coastal ice, pack ice, and polynyas. Most locations are neritic.

Foraging trip length, area of foraging zone, and distance travelled were strongly correlated, and were greatest during incubation. The estimated rate of travel (mean velocity) was constant across individu- als and stages In the breeding season. No diurnal patterns in rates of travel were detected, nor any pat- terns on different days of a foraging trip. A meander coefficient (the degree of linear travel, to give an indication of foraging activity) was constant between stages in the breeding season, and day of the for- aging trip. but was greater from 07:OO to 18100 h, suggesting increased foraging activity.

Box 99A, Hobart, Tasmania 7001 (present address: P.O. Box 3061, Launceston Delivery Centre, Tasmania 7250) Summary Several species of Eudyptes penguins breed in large, mixed colonies on subantarctic islands. However, interbreeding between species has rarely been recorded. This paper provides details of a possible hybrid Royal x Rockhopper Penguin on Macquarie Island, and summarises published records of hybrids and mixed pairs on Macquarie Island and elsewhere. Introduction There are six species of crested penguins Eudyptes and, at a number of locations, some species breed sympatrically (Warham 1975). Two species of crested penguins, the Royal Eudyptes schlegeli and Rockhopper E. chrysocome Penguin, breed sympatrically on Macquarie Island (54°33'S, 158°54'E ), where there are six mixed colonies of Royal and Rockhopper Penguins (Simpson 1985). An apparent hybrid Royal x Rockhopper Penguin (Plates 23-24) was observed on Macquarie Island in late October 1994. At that time of year, both species had returned to the island to breed after their winter departure. By the end of October, Royal Penguins had laid two eggs (the smaller~ egg', laid first, and the larger 'B egg') and were incubating, while Rockhopper Penguins were preparing to lay (Hull 1997).

The Royal Penguin Eudyptes schlegeli breeds only on Australia’s Macquarie Island and its nearby islets, about 1 200 km southwest of New Zealand. Vagrant Royal Penguins have been reported elsewhere in Australia, New Zealand and Antarctica. Reports of Royal Penguins from other subantarctic islands, including Heard, Prince Edward and Marion Islands, South Georgia and the Falkland Islands are controversial, as these penguins could also be aberrant Macaroni Penguins E. chrysolophus, and species determination can be difficult because of high variation in facial colour in both species. We discuss here the recent sighting of an apparent immature Royal Penguin on New Island, Falkland Islands. A simultaneously visiting adult male Macaroni Penguin allowed a size comparison between the two individuals. This could be the first documented sighting of a vagrant Royal Penguin in the Neotropical region.
