No fewer than nine new species were added to the Hong Kong list in the year, and another species was upgraded from Category III to Category I. These Category I additions were diverse in terms of species (two waders, one gull, one kingfisher, a bulbul, a shrike and four warblers). Some were very short-staying, being seen only by single photographers, while others remained for several days or even weeks, giving most observers the opportunity to see them. Some were identified by observers with binoculars or telescope, some from photographers and even some from sound recordings of vocalisations. The spread of first records, from Mai Po in the north to Po Toi in the south, and from Tai O in the west to Pak Sha O in the east, also showed how new species can turn up throughout Hong Kong, not just at the usual hotspots. This diversity of new records reveals how a new species could turn up to anyone, anywhere and at any time. The result of these new discoveries means that this year's Hong Kong Bird Report is dominated by first papers documenting the sightings. Nevertheless, we have still included some other reports to provide more information about birds and bird ecology in Hong Kong, including some interesting observations on nesting behavior of two difficult-to-observe species and a paper about increasing species that serves as a follow-up to last year's paper about declines. One of the innovations you will notice in this year's report is the addition of maps to the Systematic List. These are provided to show the distribution of records of selected species across Hong Kong over the course of the year. We are hoping that this can be a convenient way to easily understand the distribution of species that are scarce enough to be of interest but too widespread for every sighting to be reported individually in the list. As this is a new feature we welcome any feedback that readers may have about the maps and whether there are any improvements that could be made in future years. One thing that I have noticed while working on these maps is that the distribution of observations is not equal across all sites. More reports are received from some sites than from others. The ongoing atlas surveys by the HKBWS should help to understand the distribution of species in those areas that are less well covered, and I encourage all observers to get involved with these surveys to get as much coverage as possible. I also encourage observers to see whether they can fill any gaps by exploring new areas and reporting what they find – maybe this year you will be lucky enough to another new species for the ever-increasing Hong Kong list. As in previous years I would like to finish by thanking the rest of the editorial team for their work on getting the report completed. Geoff Welch, as always, has helped to ensure that preparation of the report is running smoothly and that all aspects are meeting a deadline so that the report can be completed in time. Gary Chow (with the help of several other members) has again been responsible for ensuring that all aspects are translated between English and Chinese. The Systematic List, the major task in the Bird Report each year, has been completed this year by a team of five individuals: David Diskin, John Holmes, Louis Lee, Matthew Kwan and Geoff Welch. Bonnie Chan and other staff at HKBWS have ensured that the practical aspects of report Hong Kong Bird Report 2015: Editorial Preface preparation are completed, including liaison with the printers and sending the report to all members of the society. Finally, of course, the Records Committee have been responsible for assessing all rarities submitted for inclusion in the Systematic List; with so many new species they no doubt had a busy year in 2015 and their commitment to the work is admirable.
