Black-chinned Fruit-Dove didn't face a major threat in the world , only distributed in the Philippines and Taiwan (are difficult to be found) . Records in Taiwan have been quite rare. If there were any resident populations in Taiwan, the number of ethnic groups should also be quite small
Their body color is very similar to forest background , if they didn't sound or call , it is not easy to be found. Activities alone in the canopy. So far, there is not much understanding of their living habits.

Dispute
The Black-chinned Fruit-Dove's population on Taiwan's island has always been an unsolved problem
Gibbs et al. (2001) and Dickinson (2003) consider this species has four subspecies, P. l. Taiwanus is only found on the island of Taiwan and is sub-endemic to Taiwan . ( their reason is : although the records is very rare in recent decades, but it shows included male, female & sub adult in different recorded )
But the other scholars believe that the individuals discovered in Taiwan are population expansion from the Philippines (Hachisuka & Udagawa 1951) . Thus , are no taiwanus subspecies (Clements2007)

As the original specimens have been destroyed (There was only one specimen at that time), even Taiwan has resident population, it may not be a valid subspecies

Malayan Night Heron （Gorsachius melanolophus） From the English name " Malayan Night Heron " we can surmise they are mainly distributed in Malaysia and the Indo-China peninsula, but now those areas are not easy to see ( seems very diffcult ) In Taiwan, there are few fixed groups in central and southern hill area. Twenty or three years ago, the Malayan Night Heron in Taiwan, the amount of rare groups, in the bird guide book is belong "rare resident" level . And their activiti es almost under forest in the hill , is not easy to observe. But We do not know why, more than a decade, the Malayan Night Heron's population gradually to the north expansion, and seems to have begun to adapt to the city environment, so in the major campuses, botanical gardens, parks and other urban green places are also more common. The original rare birds, now is the major birds on the lawn of the parks. Breeding period of 3 to 9 months, during the courtship  male will be sta...

It's out, and it's excellent! If you are thinking of birding Taiwan (or nearby) you need this book. ** May take a couple weeks before on sale overseas ** It's all you need for birding Taiwan. There is comprehensive coverage of the avifauna of the main island, offshore islands (Matsu, Lanyu, Kinmen etc), and surrounding seas. 670 birds are fully illustrated, plus compact double plates for escapees and difficult species comparisons. Eight years in preparation, the wait was wort h it and WBST is to be congratulated for producing such a useful book. The artwork is very good and of a standard meeting, or exceeding, that of international publishers. No other book illustrates the current 27 endemics, 56 endemic subspecies, other resident/migrant species and relevant subspecies better. The 190 annotated painted plates will make it the default guide for foreign birders to Taiwan - and useful for birding other countries nearby. The plates have English species names and key fi...
