Once again the annual Hong Kong Bird Report provides a summary of bird sightings in Hong Kong, in this edition covering the year 2014. Bird watching in the territory continues to go from strength to strength, especially with the ongoing development of digital photography leading to exciting observations and new discoveries. As in previous years, we have prepared a summary of observations in the systematic list as well as some papers about Hong Kong birds that we think will be of interest to the members of HKBWS. For over 50 years the HKBWS has been collecting records of bird sightings in Hong Kong. One of the strengths of this long-term and reliable dataset is that it helps us to investigate the changing fortunes of bird species within the territory. On the positive side, the new arrival and colonization of some species, especially forest species, may be obvious to long-term observers. On the negative side, some species that were previously regular have now disappeared in Hong Kong. What may be less obvious are the changes in fortunes of those species that have occurred throughout this period of observation, but for which the abundance has changed. Looking back through older editions of the annual Hong Kong Bird Report may give some indication of the change for some species, but is a time-consuming task. I am pleased therefore to include a paper on the population changes in some species as part of this HKBR. We have chosen to start with the more obvious declines in abundance, largely to draw attention to the potential conservation needs of these species. I am expecting that the more positive news of increasing species will be in a future edition of the HKBR. Of course, all this is only possible with the continued support of the HKBWS membership. Any sightings submitted to HKBWS could be useful in future to help track the changing population of the species. As you will notice from the paper in this report, records are useful not only for the rarer species but also potentially for species currently considered to be common (Barn Swallow being an example in this paper). I encourage everyone to continue to submit observations so that we can ensure that the data we use is of the best quality possible. I would like to close by once again thanking the editorial team for a job well done. The HKBR is always a team effort, and everyone involved plays a vital role in getting this report to you each year. As in the past few years, Geoff Welch has been invaluable in helping to prepare the systematic list and annual summary and compiling photos, as well as organizing all aspects to ensure the report production runs smoothly and providing useful ideas for continuing improvements to the report. Gary Chow arranges all of the translations and provides additional feedback on content that I may have previously missed. Bonnie Chan and others in the HKBWS office liaise with the printer to ensure that the report reaches final production, and then ensure that this gets sent to the members. I would also like to give thanks to the Records Committee for their work over the years in verifying observations and sightings for inclusion in the report.
