– very brightly colors Trogon and very similar to Javan Trogon.. it is so many colors put on this Sumatra endemic
– 颜色非常鲜艳,与爪哇岛的非常像是。苏门答腊特有种。
update 20240113
– just another beautiful bird that we saw it before heavy rain. It was under the shade very dark. Bird color cannot been seen, push the ISO10000 at F9 shutter speed still 1/30s …
– it is going to end the Sumatra Birding tour here, it is enjoyable we only hit into rain end of the tour which is amazing. My 2023 end with the memorize trip here. But overall is wet, muddy and few places of landslides. As we just concentrate on west-center, we mostly at Sub-montane or Montane birding. I am mostly using CANON RF200800 and CANON R3 for rainforest environment. It is challenging with such long focal length with small aperture (will share more experience later regard the lens)
– this bird seem quite common any where here, we seen and heard almost any where even night roosting at montane area. Such a beautiful bird and hope to see the Java version soon (which I missed 16 years ago)
– another Christmas spend with my best guest, buddy .. this time choose have special target tour to Sumatra. After whole day travel, we arrived first birding accommodation from 4am – 4pm .. 1+ hour flight and ~7hours drive ..next day morning, we decided to change ours original plan for Ground Cuckoo, but I didn’t see one and only heard twice for almost whole day in a very lovely forest.
– this bird flying in-front of us while we waiting ours target and having ours hot tea session. What a beauty, still remember ~18 years ago I missed my Java trogon … and today see this very look a-like endemic of Sumatra ..
a very similar to Borneo Black-headed Pitta and Garnet pitta call and similar look. But it is an endemic to Sumatra island
– 与婆罗洲的黑头八色鸫,西马的榴红八色鸫非常像。叫声也很像。
update 202401
– while we looking for the Ground-cuckoo, that area actually plenty of this Pitta. We saw one just 3-5feet from us stand there and cannot take any picture and this bird same just came to us and look at us .. beautiful moment even not a good picture compare to previous feeding station picture but it is a different satisfaction to find one wild..
– saw this bird yesterday while waiting ours target, the bird stand 5 feed at us looking at us and definitely not able to focus to have a picture. Today, go to the “easy side” but 2 landslides happen car cannot drive through, we birding and walk ~8km to reach. While we cooking coffee, the bird calling and came…
– active and moving within bushes and making various sharp, loud call
– 移动快在丛里,叫的蛮好听+响亮。
update 202312
– arrived the famous Tapan road, stop the first location as saw the whistling-thrush on the road and not long heard a not so familiar call and soon Dwi say it is a babbler and make some small effort to have it in view and not so open photo due to very lowlight. In the noon time very soon we have another chance to photograph it ..
– a very beautiful Ground-Cuckoo and it is as beautiful as the Bornean Ground-Cuckoo. it is shy, move fast on ground
– 非常漂亮的地鹃,就如婆罗洲地鹃一样的美。通常害羞+在地上快速走动
update 202403

####
update 202401
– no one can explain how excited we were when we got this super good view of this bird after 2 full morning waiting and this beautiful bird give us amazing view at the “not common” spot
– 很难讲诉我们当时的心情,等了2天后。这鸟在“鸟点”外出现。真的太美,兴奋。
#####
update 202312
– one of ours Sumatra birding main target
– we spend 1 morning at “promising spot” but bird no show, and spend next morning again but just heard it 2 times. But luckily we make decision to walk around and finally with the Dwi sharing the behavior of the bird… manage to have good view and picture.
– a large and rare Pitta with overall blue and brown for male, large beak
update 202312
– a target bird, we found one while ours night birding after we got ours Rajah Scops-Owl. Happy to found one, before we heading to “feeding spot”. But we only have 2 chance which happen before enough light for better quality of picture.
– Any how it is 20th Pitta for guest…
– Am using new CANON RF200800 which is small aperture lens. But with a travel tripod assist, I managed to have most the picture hit on at ~1/10-1/30
as other Peacock-Pheasant, it is shy and look at the body feather pattern, this Peacock-Pheasant simply beautiful
update 202312
– as other Peacock-Pheasant, it is shy and not easy to have a good view in the wild. This pair of Sumatra endemic, will show up at one of the feeding station but this male will chase any bird that come close make us only saw the main target Schneider’s Pitta (2 times before light, 1 time night)
8. Sunda Forktail, 姬燕尾, 姬燕尾, Enicurus velatus, ヒメエンビシキチョウ
– as other forktail, a small and very shy bird. But it is a beautiful one with rufous head instead ovarall black-and-white.
– 与其他燕尾一样,都是很怕人。也很不一样,大部分燕尾都是黑+白
update 202312
– while we walking on the trail for Ground Cuckoo, this bird always infront us but keep a distance. We didn’t spent too much time for it as rushing for the main target
– overall bulbul, leafbird and most of the colorful birds, songbirds are very low density at west Sumatra
– 一只非常有条纹的鹎,整体呈灰色。
– 在苏门答腊,鹎,叶鹎,鸠都几乎很难看到。
update 202401
– the famous Tapan road had few landslides so we mostly walking at the road (~15-20km) but overall Bulbul, leafbirds, dove almost not heard or visible … but this endemic came down to feed berry while we have good view of ~12 Blue Nuthatch.
– as other frogmouth it should be nocturnal and always good to meet one in day time look cute.
– 蟆口鸱是夜行鸟,早上见到他绝对是兴奋的一克
update 20240108
– one of ours main target, but missed the night and morning version on day1. But got it on day 2 for both night and day version. It really look like Bornean Frogmouth with “short” tailed
a owl we always heard and wanted to see in Borneo, even it can be different sub-species or species (in future) but It is much easier here .. a small owl like other small and active in dark
– even it is high chance to find it’s roosting bird, but we always like to find the bird in night. Ours’ first morning, have a good try and the bird didn’t make any sound… I am amaze how I found it (haha, by the thermal camera.. found it once very near and 2nd time quite a distance)
– as other Wren-Babbler this one same moving really fast and active surprise it is not very shy. Moving in pair and bush fast
– 与其他鹪鹛一样动作非常快,草丛中跳来跳去,可是好像不是很害羞。
update 202401
– almost not possible to get the picture of this endemic bird with bird watcher … but lucky or not so lucky the main target is no show … while we waiting, I personal looking for this bird and lucky to have this better moment for photo and I actually got 3 in 1 frame.
– very common along the Tapan road, but just no luck to have better photo opportunity. Typical treepie call and big-long bird
update 202401
– saw so many of this bird but just dint get a chance to have good photo
– 蛮普通的见不停,可是每一次近点的。
15. Red-billed Partridge, 红嘴山鹧鸪, 紅嘴山鷓鴣, Arborophila rubrirostris, アカハシミヤマテッケイ, Puyuh-gonggong sumatera

update 202401
– another bird suppose to hope come to feeding station but not, but we managed to heard and found the bird. Again this is another reason setup customize button for my R3 which can shoot in complex environment (just like this) point the focus points (I using 5 point) on to any part of the bird and eye will be lock focus ..very useful and suitable for people like shooting wildbird in move
The barred eagle-owl (Bubo sumatranus), also called the Malay eagle-owl, is a species of eagle owl in the family Strigidae. It is a member of the large genus Bubo which is distributed on most of the world’s continents.

Combination of small size, all rufous color, lack of prominent facial border, and only limited markings below separates it from all other owls on Sri Lanka.
