The Global Biodiversity Information Facility (GBIF) is an international initiative that aims to enable the worldwide exchange of biodiversity-related data through the internet. Within a three year project funded as a German contribution to GBIF the information about primary types of birds (and other vertebrates) in German collections will be made available through the internet (http://www.gbif.de). This information includes the original description, status (syntypes, holotypes, etc.), current taxonomic classification, collecting data, mode of preparation, current location as well as digital images of type specimens. So far, 900 of the expected 4000 primary type taxa of birds have been investigated and digitised. It is expected that by the end of the... |

Hellebrekers, W.Ph.J.; Hoogerwerf, A.. |
The present authors independently from one another studied oological material from Java. The results of their studies are combined in the present paper. Hellebrekers deals with three collections, held by the Rijksmuseum van Natuurlijke Historie at Leiden, brought together (a) by M. E. G. Bartels and his sons (4770 shells), (b) by J. G. Kooiman (280 shells), and (c) by H. J. V. Sody (175 shells). Of these collections those made by Bartels and Sody consist almost exclusively of eggs from West Java, while that made by Kooiman originates from East Java. Hoogerwerf gives details of 1020 shells of his own collection, almost all of which originate from West Java. These were obtained after the appearance in 1949 of a paper in which he published the colour... |

INTRODUCTION Father Verheijen (in press) has given a narrative of his visit to Roti, with a list of all birds recorded from material, personal observations, and hearsay. Although several of Verheijen's own field observations are entirely reliable, other species mentioned by him cannot be regarded as of anything but very doubtful occurrence. Therefore I have considered it useful to compile a list of those birds which are now known from collected specimens. Previous to Father Verheijen's studies, ornithological knowledge of Roti rested entirely on a visit to the island made by the anthropologist Dr. H. F. C. ten Kate in 1891 (22 August — 9 September). During his stay ten Kate did some collecting of miscellaneous zoological objects, which he forwarded to... |

In preparing a Handlist of the birds of the Moluccan islands, I found among the material in the Rijksmuseum van Natuurlijke Historie, Leiden, a race of Dicrurus that needs description: Dicrurus bracteatus morotaiensis nov. subspec. Diagnosis: Distinguished from atrocaeruleus Gray (1860) — Batjan and Halmahera — by smaller culmen and wing. Habitat: Island Morotai (N. Moluccas). Measurements in mm: ♂♂ culmen: 29; 29; 28.5; 28.5; 30 wing: 150; 148; 147; 152; 149 ♀♀ culmen: 27; 29; 30 wing: 149; 147; 145.

For over a century the sunbird Anthreptes malacensis has been known to occur on the Soela Islands where it reaches the eastern limit of its distribution, and when Shelley (1877) named Anthreptes celebensis, now known as Anthreptes malacensis celebensis, he included the Soela Islands in its range. In subsequent years apparently only Hartert (1898) has in the briefest possible way discussed specimens from the Soela Islands, stating that they were: "quite like Celebes specimens". At this the matter has rested with the result that in the latest list (van Bemmel, 1948) the Soela Islands are still included in the range of Anthreptes malacensis celebensis. When Stresemann (1932) restricted, in the Celebes, the range of A. m. celebensis to the southern peninsula,... |

Gibson-Hill, C.A.. |
In a paper on some birds from Sumatra in the Leiden Museum Dr. Junge (1948, pp. 314-15) lists two males of Limosa lapponica baueri Naum. taken by Mr. Van Heurn on the beach at Tandjong Tiram in the Deli district on 14 November 1921. In a short discussion on this record he refers to the fact that Vorderman (1890, p. 416) gives this species as probably occurring in Sumatra, and subsequently Robinson & Kloss (1923, p. 326) and Chasen (1935, p. 37) list it without query or comment. Dr. Junge adds that he failed to find the reference on which the later authors decided that the bird was definitely known from Sumatra. It is probable that no such reference exists and that Dr. Junge's paper constitutes the first authentic published record of the occurrence... |

The first Western Palearctic record of a Red-footed Booby Sula sula (L., 1766), a brown whitetailed morph observed on Cima (Cape Verde Islands), is described. The status of this species in the tropical South Atlantic Ocean is evaluated. At present, Fernando de Noronha is the only South Atlantic stronghold of the species (ca. 4000 individuals; cf. Oren, 1984). The species has disappeared, or almost so, from other islands (St. Helena: absent; Ascension:0-30 individuals; Ilha da Trindade: less than 100 pairs). A link may exist between the apparent recent increase of the population of Fernando de Noronha and the apparent recent decline of the Trindade population. It seems possible that the Trindade population for some unknown reason has migrated to Fernando de... |

INTRODUCTION When in December 1960 the R.A.O.U. Checklist Committee was reorganised and the various tasks in hand were divided over its members, the owls were assigned to the author. While it was first thought that only the Boobook Owl, the systematics of which have been notoriously confused, would need thorough revision and that as regards the other species existing lists, for example Peters (1940), could be followed, it became soon apparent that it was impossible to make a satisfactory list without revision of all species. In this paper the four Australian species of Strigidae are fully revised, over their whole ranges, and the same has been done for Tyto tenebricosa. Of the other three Australian Tytonidae, however, only the Australian races have been... |

Data are presented on the diet of Cory's Shearwater Calonectris diomedea borealis (Cory, 1881) resulting from stomach investigations based on 18 birds from Hierro (Canary Islands), 5 from Selvagem Grande (Selvagens or Salvage Islands), 2 from São Miguel and 1 from São Jorge (Azores), collected between 1977 and 1981. These data confirm the general idea that this shearwater feeds principally on fish and squid. The glandular stomachs of 9 birds from Hierro contained significant quantities of food, varying in wet weight from ca. 4-40 gm; in four cases more or less complete squids were present, all Ommastrephes bartrami (Le Sueur, 1821). In addition, the gizzards of all 26 birds, except one, contained fragments of squid beaks belonging to 12 species. Several of... |

INTRODUCTION Hardly any group of birds is of a greater interest to the zoogeographer and to the student of evolution and speciation than the family of the Zosteropidae. It was with the fact in mind that no conclusions as regards these fields of investigation could be drawn without the reliable base of a good classification that Stresemann (1931) 1) undertook a revision of the IndoAustralian members of the family. Stresemann's revision is a pioneer work that will long remain the base for any further work in the group. Since 1931, however, 45 further names have been given in the Indo-Australian group of the Zosteropidae, adding two valid species and about 25 valid races to the number already known. Though several partial revisions have greatly elucidated... |

INTRODUCTION In this, the second part of my revision of the Zosteropidae, 26 species are dealt with, all belonging to the genus Zosterops. The remaining 12 species of the genus and all the other genera, will be treated in the third part, the preparation of which is in progress. Unfortunately, it becomes more and more clear that no revision of the Pacific forms of the Zosteropidae can be really satisfactory without a visit to the American Museum of Natural History, where all the material of the Tring Museum and of the Whitney South Sea Expedition is assembled. Even though the co-operation of the authorities of that museum is above praise, I have usually been able to examine part of their series only, and no type specimens at all. More important is that the... |

Since the publication of my paper on birds from Formosa (Mees, 1970), a few more collections have been received from the same source. A ban has now been placed on hunting and export of wild birds by the government of the Republic of China — an enlightened and overdue piece of legislation — with the result that the connection has come to an end and no more material is to be expected from Formosa. Although the later collections do not contain anything spectacular, a few records merit publication and for the reason stated this is a good moment for doing so. I take the opportunity to report on a few specimens from our old collection and from other sources. Appended are a bibliography of ornithological papers that have appeared since Hachisuka & Udagawa's... |

It is self-evident that as the avifauna of a country becomes better known, the number of additions to its avifauna one can expect to make in a given period, must decrease. On the other hand, it may be said that for the same reason the value of each addition increases. During a stay in Suriname of about a year in 1965/66 I found 17 species of birds which had not been previously recorded from the country (Mees, 1968). A second stay of a year's duration (November 1971-November 1972), yielded eleven additions to the avifauna of Suriname: nine of these are based on material collected, whereas two are based on field-observations only. With one of the species being represented by two subspecies, and one held over from my previous stay when lack of comparative... |

The family of the Zosteropidae encloses, besides the very large and uniform genus Zosterops, a number of aberrant forms, especially in the East Indian Archipelago, that, though doubtless closely related to Zosterops, are too distinct to be united with this genus without objection. Several authors have engaged themselves with the problem of the classification of these forms, without arriving at a definite conclusion (cf. Hartert, 1897, Lophozosterops; Stresemann, 1940, p. 66, Pseudo zosterops). The inclusion of many of these forms in the genus Zosterops, as propagated by Hartert, and by Chasen (1935), is no final solution either, and later workers, such as Delacour & Mayr (1946), Delacour (1946), and Voous (1948), investigators who are certainly not in... |

An evolutionary understanding of the complex mating systems of megapodes has been impaired by a historical and simplistic classification system that assumed all species to be monogamous. This approach has been challenged by behavioural ecology theories that emphasize the primacy of the individual attempt to maximize its own fitness. From this point of view the remarkable incubation techniques and the recently described behaviours of some clearly promiscuous species can be more clearly understood. In particular, the influence of the type of incubation-heat source on the mating system is paramount. |
