A new species of African Forest Robin from Gabon
(Passeriformes: Muscicapidae: Stiphrornis)


Here is the abstract from a journal article in Zootaxa:

We describe a new species of forest robin from the Gamba Complex in southwest Gabon. This common bird, Stiphrornis pyrrholaemus sp. nov., inhabits primary lowland forest and forages on or near the ground like the other members of the genus Stiphrornis of central and western Africa. Unique phenotypic features of the new species include the male’s bright orange chin, throat, and breast, creamy yellow belly, olive green back and rump, and gray flanks. Mitochondrial sequence divergence corroborates our assessment based on its distinct physical characteristics that this is a new species, and suggest that Stiphrornis erythrothorax is likely the most closely related congener.

Summer Birding in Taiwan

This past summer, I spent about seven weeks in Taiwan. My primary purpose was to visit with family, but, needless to say, I did a fair amount of birding while there. I was also Taiwan earlier in the year for the Chinese New Year. My birding report for that trip can be view here.

To prepare for the trip, I studied the field marks for the birds I was likely to see, as well as for a few target birds. I used Wu Sen-Hsiong's Field Guide to the Wild Birds of Taiwan as my primary guide, and Severinghaus & Blackshaw’s New Guide to the Birds of Taiwan as a supplement. Brief reviews of both guides can be found in the post below (scroll down). In addition to field guides, I also made use of publicly accessible field recordings from the Macauley Library to learn the various calls and songs of Taiwan birds. Being a tropical country, Taiwan’s forests are very thick with vegetation, making it difficult to find and identify birds by sight alone. Knowing the songs and calls made it easier to track down birds and identify them.

Kaohsiung County and Tungkang River

I did most of my birding close to my in-law’s home in western Kaohsiung county, near Daliao. Click for map, as well as in the agricultural areas along the Tungkang river in Ping Tung county. Click for map. These areas are located in the southwestern alluvial plains of Taiwan at an elevation below 50 meters. The habitats encountered were a mix of agricultural lands, mostly rice paddies and cane fields, as well as low hills that were largely overtaken by grasslands and bamboo thickets, with a few hardwood trees scattered about. A very small pond was also present. The highlights were the Painted Snipe and the Zitting Citicola – the Snipe for its wonderful plumage and the Cisicola for its entertaining flight display.

These are my observations:
Bamboo Partridge
Barn Swallow
Black-crowned Night Heron
Black Drongo
Black-naped Monarch

In addition to local birding, I also made a few field trips to Kenting National Park at the southern tip of Taiwan, Alishan in central Taiwan, Taipei Botanical Garden in the north, and a very brief trip to Victoria Point in Hong Kong.

I have been to Kenting a number of times over the 15-20 years I have been visiting Taiwan. Overall, I have been very disappointed with the birding in the park, particularly with the Sheding Forest Recreation Area. The Baisha beach and other coastal areas have also been somewhat disappointing. The only bright spot I can recommend in Kenting is the Longluan Lake area. That being said, Kenting is a world renowned place for hawk migration, although I have never been there at that time. The highlights were the Mountain Scops Owl and the Hwa-mei.

Here are my observations:

Alishan was the highlight of the trip. Its highest peak is Datashan (2663 m). The elevation in the Alishan Forest area is between 2200-2400 m. The mountain range offers a chance to see many of the endemic birds, as well as other high elevation species. And the scenery was spectacular and sometimes draws your attention away form the birds.

Getting to Alishan was half the fun. We took a train to the Chiayi station. From Chiayi, we took the mountain railroad up to Fenchihu (1000 m). Fenchihu is an old railroad town with a shopping area and plenty of places to eat the famous Fenchi lunchbox – basically rice, eggs, and pickled veggies. From Fenchihu, we were picked-up by shuttle van and taken up to our hostel. We spent three days up on the mountain at the Jane-Su Homestay in Chiayi County. The homestay is situated at 1450 m, in the middle of a high mountain oolong tea plantation, and affords a spectacular view of the Alishan area. One feels as if they were floating on a sea of clouds. I highly recommend the homestay!

Although the mountain roads are relatively well-marked, they can sometimes be difficult to navigate, particularly for the out-of-towner. Summer time is also typhoon season in Taiwan. As such, is it not uncommon to have small mudslides or wash-outs. As such, we hired a local guide from the homestay to drive us around.

I would typically rise just before sunrise, and bird along the roads around the homestay. The vegetation was a mix of conifers, broadleaf trees, and bamboo. Activity was extremely high – at some points at felt a bit overwhelmed with all the birds. Anyway, I did manage to regain my composure and focus on the birds at hand.

The guide would pick us up around 7:00 am, and take us around to some of the local scenic hotspots such as Titanic Rock, Shenmu (Sacred Tree), the Twin Sister Lakes, and a grove of ancient cypress trees. We also visited a local coffee plantation, and a oolong tea plantation operated by the homestay owner.

The highlights of the Alishan trip were the endemic birds (*), particularly the Taiwan Yuhina and the White-eared Sibia. Other notables include an adult Malayan Night Heron and the Large-billed Crow.

Here are my observations:

The Taipei Botanical Garden is situated in downtown Taipei, close to the National Taiwan University. Although the setting was primarily urban, birding in the small park was surprisingly good. We also visited the Riverside Park near the Xindian River. The highlights of the garden were two juvenile Malayan Night Herons, and a nesting Black-browed Barbet. The Riverside Park was home to a small colony of Sacred Ibis that apparently escaped from the Taipei zoo and are now breeding.

Here are my observations:

I also made a very brief (overnight) trip to Hong Kong. Didn’t have much time to bird, but I did manage to sneak about 2 hours in to walk the Hong Kong Trail around Victoria Point. It was rather late in the morning (10:30) and quite warm (40 celcius), but I did manage to see and hear a few birds. The highlights were the Red-Whiskered Bulbul and the Blue Whistling Thrush.

Here are my observations:
Black Kite
Blue Magpie
Blue Whistling Thrush
Crested Myna
Eurasian Tree Sparrow
Japanese White-eye
Lesser Sulphur-crested Cockatoo
Light-vented Bulbul
Masked Laughingthrush
Oriental Magpie Robin
Red-whiskered Bulbul


Overall, I observed about 82 species – 43 of which were lifers for me. The overall highlight of the trip was the Taiwan Yuhina and the White-eared Sibia. Although these birds are fairly common in the mountains, I just found them absolutely spectacular to watch There were also a few disappointments. Taiwan has 16 completely endemic species according to the Clements Checklist of Birds (or 22 by IOC guidelines), all of which I had targeted for the trip. I observed eight of the endemics on this trip (Collared Bush Robin, Steere’s Liocichla, Taiwan Barwing, Taiwan Bulbul, Taiwan Hill Partridge, Taiwan Laughingthrush, Taiwan Yuhina, and White-eared Sibia). There are still seven more that I did not get the opportunity to see, particularly the Formosan Blue Magpie. We had intended to spend more time in the moutains near Huben and Hualien, but two typhoons (Kalmaegi & Fung-wong) hit the island and dumped several feet of water, and washing-out a number of roads ad bridges, as well as causing a few mudslides.

On the bright side, I now have an excuse to go back!

Guide to Birding in Taiwan

Taiwan is a wonderful place to watch birds. Each year, approximately 450 species of birds can be found on the small island. As such, Taiwan has the second highest bird density in the world (Madagascar is first). In addition, Taiwan has 15 endemic species, the majority of which can be found in the mountainous regions.

Geographically, Taiwan has many features that make it an attractive place for birds. The majority (almost 70%) of the island is comprised of mountains with elevations of 100 meters or greater – more than half of which are over 1000 meters. The tallest peak on the island is Yushan (Jade Mountain), with an elevation of 3,952 meters. The remainder of the island is primarily alluvial plains - with a lots of agricultural development (and lots of people). As such, Taiwan offers a wide variety of birding habitats, including coastal wetlands, estuaries, grasslands, agricultural areas, tropical rainforests, broadleaf & bamboo forests, and high alpine forests.

The other feature contributing to Taiwan’s high bird density is it location. Taiwan is located in the western Pacific, about 130 km east of mainland China. The Tropic of Cancer passes directly through the southern part of the island. More importantly, it lies at the midpoint of the migration routes for birds traveling between their summer breeding grounds in Japan, China and Siberia, and their southern wintering grounds in the Philippines, Indonesia, and New Zealand.

Logistically, it is pretty easy to get around. The roads are good and the accommodations and food are reasonably priced. For those interested in planning an itinerary, I would suggest reading the trip reports posted on Surfbirds, particularly those of Andy Mears and Albert Low.

FINDING A FIELD GUIDE

After binoculars, a good field guide can be a birders most important tool. I have used several in the past, such as MacKinnon and Phillip’s Field Guide to the Birds of China, James Wan-Fu Chang's Field Guide to the Birds of Taiwan, Wu Sen-Hsiong's Field Guide to the Wild Birds of Taiwan, and Severinghaus and Blackshaw’s New Guide to the Birds of Taiwan. All the guides are good, but each has its strong points, as well as its drawbacks, as I discuss below.



Field Guide to the Birds of Taiwan

James Wan-Fu Chang's Field Guide to the Birds of Taiwan covers 458 species. Although the common and scientific names of each species is given in English, the main text is written primarily in Chinese, making it problematic for birds not versed in Mandarin. However, there are very brief English language descriptions of the range, habitat and status of each bird which I found helpful. In addition, reasonably good range maps are also shown for each bird (excluding vagrants). On the down side, I found the plates to be somewhat below the standard that most birders have come to expect. Paintings appear hastily done and often do not sufficiently show key field marks which are helpful in distinguishing similar species.


Field Guide to the Wild Birds of Taiwan

Wu Sen-Hsiong's Field Guide to the Wild Birds of Taiwan (ISBN 957-9578-00-1) covers 444 species. Like Chang’s guide, it is also written in Chinese. However, with the exception of the common and scientific names, there are no English language descriptions of any kind. That being said, the range maps and paintings are far superior to Chang’s guide. Key field marks are clearly indicated, and paintings of birds in flight are also shown when appropriate (e.g. gulls, terns, shorebirds, hawks, etc)


Field Guide to the Birds of China

MacKinnon and Phillip’s Field Guide to the Birds of China is more extensive, covering 1329 species. This guide addresses some of the drawbacks of the previous two guides. For starters, it is written entirely in English. The paintings are generally of high quality, and differences between subspecies are indicated. Range maps are also shown on the page facing the paintings. The descriptions of many (but not all) species are fairly well detailed, and the ranges for subspecies is also described. The guide does have some minor problems, which are probably unavoidable. Because of the number of species described, the guide is quite bulky - and somewhat expensive. In addition, the descriptions are in the back of the guide, rather than on the page adjacent to the paintings, making it somewhat inconvenient to use. Some of the species descriptions, particularly those of the Taiwan endemics, seemed to have been glossed over. And although most of the paintings are of high quality, not all were. Overall, I think they are slightly inferior to those of the Wu guide.


New Guide to the Birds of Taiwan

Severinghaus and Blackshaw’s New Guide to the Birds of Taiwan has the least coverage of any of the guides - only 201 species covered. Species covered include the endemics, the most common summer/winter residents (approx. 150 birds), and the migrants one is likely to see. Rare visitors and vagrants are not represented. In addition, the paintings are not the best, and only show a small handful of birds (about 45 birds on eight color plates). The artist is apparently the same person who did the paintings from the Chang guide. A few other birds, including hawk silouettes, are done in b&w pencil drawings, and are surprisingly good. The guide also has a very strong upside, making it indispensible. For starters, it is written in English (and Mandarin). It has excellent descriptions of the habitat and subtle behaviors that are very helpful in making IDs. In addition, the verbal descriptions of the bird calls and songs are also remarkably good.

If I could only choose one guide, my personal recommendation would be Field Guide to the Wild Birds of Taiwan by Sen-Hsiong Wu. It is jointly published by the Taiwan Wild Bird Society and the Wild Bird Society of Japan. I picked-up a copy in Taiwan for about $30. If I could add another as a supplement, it would be the Severinghaus and Blackshaw guide. This one is a bit harder to find, as it is out of print. I found a copy in an on-line antiquarian book store for about $25.

RESOURCES FOR BIRD IDENTIFICATION

When planning any birding adventure, it is always a good idea to do your homework ahead of time. That means familiarizing yourself with the birds you are likely to see. For me, that entails learning the field marks, the calls and songs, as well as the best places to find birds once you arrive at your destination.

For field marks, a good place to start is with a field guide, as stated above. In addition, there are also a number of sites on the internet where you can view photos of birds. Sometimes this can be very helpful, as painting don’t always do a bird justice. For Taiwan, I have found Birding in Taiwan and Oriental Bird Club to be two excellent websites.

Field Recordings

Learning the calls and songs is a must for Taiwan. For birds calls and songs, there are a number of commercially available tapes and CD’s. While these are helpful, they do pose a few problems. For starters, they tend to be costly. In addition, only a limited number of species are represented, and then only by their most common songs and calls. Alternate songs and calls are frequently left out. Fortunately, the internet comes to the rescue again. A number of websites have made field recordings available. In addition to the calls and songs, the location of the recordings is also given, allowing one to distinguish variations in calls between subspecies.

The best site - by far - is Cornell’s Macauley Library. This site contains countless hours of field recordings of many (but not all) birds across the globe. Most species are represented by multiplue recordings, which typically include alternate calls and songs. The Cornell site does have its downside. For example, because they are field recordings, they sometimes contain background noise, such as traffic, barking dogs, wind, and other birds. In addition, not all the recordings are publicly available at present, and not all birds are represented.

In addition to the Cornell site, there are also several good sites that are specifically dedicated to Taiwan birds. These sites contain a fair number of field recordings that can be used as a supplement to the Cornell recordings. Moreover, one may also find recordings of species that are not reprensented in the Cornell collection. In the case where the Cornell field recordings contain background noise or are of poor quality, one may find a better quality recording. In addition, these website typically contain other useful informations, such as general descriptions, data on range and habitat, life histories, and photos. For Taiwan birds, the most useful sites are Birds of Taroko Gorge, the Taiwan Goverment Information Office, and Wayne Hsu’s Page.

Birding Guides


Birdwatching in Taiwan

Where to go? That is best determined by reading trip reports or picking up a copy of a birding guide. Although I have never used a birding guide in Taiwan, there are several that are commercially available. The one that appears to be the most recommended is Birdwatching in Taiwan, by Rui-De Shi. This guide covers 52 birding area in Taiwan, as well as some of its surrounding islands. According to the publisher’s description, “the book also introduces the distinguishing features of ecosystems, the best seasons for visiting, and transportation details”.

OTHER RESOURCES

It is also a good idea to plan your itinerary in advance. To do so, it is helpful if you know a little something about the geography and culture, as well as the infrastructure and accommodations, of the place you are visiting. The internet offers a good resource for this type of information. As I have stated above, trip reports from other birders can be very helpful. For those, I have found Surfbirds to be the best site. Bird blogs are also good resources. I have added a few Taiwan bird blogs to my blog role on the right column of this page. There are also a number of eGroups and listservs through which one can get in touch with others who live or bird frequently in the region of interest. For Taiwan, I have found Yahoo!'s Oriental Birding Club to be very helpful. One could also do a Google search for more sites.
