Hardcore Birding: Mindanao Edition

Text and photos by Pete Simpson


This was a Wild Bird Club Philippines trip with three members from Manila (Willem van de Ven, Janjaap Brinkman, and Nikki Dyanne Realubit) and one from Thailand (Gawin Chutima). It was a condensed version of my previous tour, Mt Talomo from Davao, to ComVal via Panabo and PICOP ending with an airport drop back in Davao. All that in 5 days.

Mt Talomo delivered wonderfully. Four Japanese Night Heron reported on the first morning and one watched feeding in great light the following morning. These are an endangered species, rare and very difficult to see. We are lucky that they choose to spend the winter in the Davao area, and I try to ensure that they are not disturbed by my visits. They are a shy and cryptic bird that stick to the shadows and I confess that in the early days they would sometimes only be located when flushed. With more knowledge of their habits we are able to locate and observe the birds from a safe distance, they are aware but appear not concerned by our presence. The land owners and managers had been aware of these birds before birdwatchers knew, though they didn’t know the species or significance. Thankfully in this farmed area that the birds have chosen to spend the winter they are protected. My fear is that if disturbed from this site they would relocate and be eaten.

Whiskered Flowerpecker was seen briefly but in good light that first afternoon, followed by a fine display from a pair of Cryptic Flycatcher. While searching for those Cryptic Flycatcher we stumbled across Southern Silvery Kingfisher perched on the rocks of a mountain stream. Bonus sighting for the day was to have both forms of Purple-throated Sunbird on the same flowering tree. Davao is at the border between the red bellied and widely distributed ssp tricolous form and the yellow bellied central to west Mindanao and Sulu only ssp juliea form, the latter split already by HBW as Orange-lined Sunbird. In contrast to my previous tour the owling started well with instant response from Everett’s Scops Owl.

After second helpings of Japanese Night Heron the following morning, and multiple helpings at the buffet breakfast, we headed to Panabo where the Chinese Crested Tern behaved as they should, two birds (possibly four percent of the remaining world population) at high tide perched atop their favorite bamboo poles.

We had a short time at ComVal on day two, arriving from Panabo in the late afternoon to fog and the threat of rain. Lina’s Sunbird was difficult and I feared a washout, but a small flock of Mindanao Lorikeet saved the session.

The following morning we were up on site before dawn. Bukidnon Woodcock flew over roding a few times and Mindanao Scops Owl came close but remained hidden. We were hopeful of a clear dry morning and disappointed when the fog rolled in before 6am. Thankfully the discovery of a nearby fruiting bush means our short time on site was not wasted. Red-eared Parrotfinch was the bird that led us to the bush but once there we watched as mixed flocks moved through; Olive-backed Flowerpecker, Cinnamon Ibon and Rufous-headed Tailorbird passed and then Linas Sunbird visiting a flowering vine. After an hour Flame-crowned Flowerpecker joined the action. Winter visitors were in evidence here too with Mugimaki Flycatcher and two Olive-backed Pipits.

I did add another species to the already impressive ComVal site list, a surprising but not positive addition. Here at 1400masl the only starling should be Short-tailed Starling. Asian Glossy Starling are usually only up to 1200masl with Short-tailed coming in above 1000masl, meaning the overlap is should be only 1000-1200masl. At that altitude on Mt Talomo I have seen them mixed flock. We found two immature Asian Glossy sitting with a flock of Short-tailed, a new site record and possibly a further indication that the trashed habitat is attracting more trash birds.

From ComVal we continued east to Bislig for two days in PICOP, and as is customary upon arrival, we checked out Bislig airfield. But before that we had time for a quick look at Lake 77, previously a haven for resident and wintering ducks. Today there were none, I fear all were trapped for the cooking pot. Another wet birding session at the airfield with no chance of Grass Owl, but we did see both resident duck species and hear many Middendorff’s Grasshopper Warbler.

We suffered the authentic PICOP experience the following morning, the uncomfortable early jeepney ride to road 42. The owling was as it had been the previous week, frustratingly quiet. That frustration continued into our daytime birding, road 42 seems to have lost its mixed flocks. We walked almost to the end where just one of the group was treated to close views of two Mindanao Wattled Broadbill, the birds making their way silently back in to the forest before the rest of us arrived. We did see birds, Black-bibbed Cuckooshrike perched for scope views, Mindanao Blue fantail and Rufous Paradise Flycatcher were new for most, Philippine Leaf Warbler remain responsive and we managed all four species of Bulbul. The following day at the cemetery on road 4 we suffered an equally fruitless owling session, just a roosting Philippine Serpent Eagle in the spotlight. It was a tough morning attempting to salvage a half presentable PICOP list but the highlights were an early Rufous-lored Kingfisher, a lone Writhed Hornbill and great views of Striated Wren-Babbler. PICOP has less than one month to get its act together or there will be a lot of disappointed tour groups at the start of 2019.

On our way back to Davao we stopped again at Panabo to confirm that the CCTs have changed their habits since last winter, their absence on this day showing they must have new unknown bamboo pole to sit on at high tide.
This was probably a little more hardcore than the average WBCP trip, but I suspect we saw a lot more endemics and rare winter visitors than the usual fare.
