A morning spent around the Loop trail at Bong Substation in Cuc Phuong produced only few exciting birds, although the morning drive started off good with at least 5 Malayan Night Herons and 2 Bar-bellied Pittas being flushed off the road.
First birds seen at the start of the Loop trail included a couple of smart Rufous-throated Fulvettas. A Chestnut-necklaced (Tonkin) Partridge was calling close by but didn't show itself. The usual suspects turned up further along the trail with plenty of Buff-breasted and Grey-throated Babblers. A few flycatchers showed up near the 1000-year-old tree, including many Black-naped Monarchs, 1 nice-looking male Asian Paradise Flycatcher, 1 female Fujian Niltava as well as 2 Hainan Blue Flycatchers. Mostly passerines were encountered during the walk but woodpeckers were heard and seen too - mainly Bay Woodpeckers and Greater Yellownapes but 1 woodpecker that was heard sounded reminiscent to Red-collared.
Just before the ancient tree a small birdwave consisted of Limestone Leaf-warbler, White-bellied Erpornis, Black-browed Fulvetta and again, Rufous-throated Fulvetta.
Towards the end of the trail a pitta-sized brown bird was flushed.
2 Yellow-bellied Warblers and a flock of Brown-backed Needletails finished off the morning's birding.
Nothing of interest was seen on the way out of the park.
