Quest for Silver Oriole

Silver Oriole - One of the star species of Guangdong's forests

The Silver Oriole is a relatively little known species that breeds in southern China and over winters in mainland South East Asia. It is listed as Endangered due to their limited range and heavy habitat loss of the tropical and sub-tropical forest throughout their range. They are probably one of the rarest breeding species in Guangdong, being rather elusive and not often seen. It is estimated that their global population is no more around 2000 individuals and decreasing.

I've been to Nanling in the past where they are most often recorded but failed to locate them. Last year having heard the news of a pair of Silver Orioles breeding at Liuxihe National Forest Park, I really wanted to give it a try this year. Sure enough, around mid May we got news that the pair had returned to the exact same location! Captain and Kei decided to go on the 25th of May, which I unfortunately had work. Luckily I was able to join another group organised by Principal Kwok. We wanted to get there as early as possible, so we met at 3am and transferred to the Huanggang Cross-boundary shuttle buses to go over the border, where we met with our driver at 4am. Weather was not looking particularly good, we could only hope that the heavy rain ease off by day break...

A quick nap in the van and we arrived at Liuxihe in just two and a half hours! We got off at a restaurant where the footpath up hill is located just to the back. Luckily for us, the weather did improve and we were able to remain dry for the rest of our journey!

Road next to hiking trail entrance

The location of the Silver Oriole is roughly at (23.742036, 113.843287), you can access the area through a footpath from behind the restaurant at the base of the hill, the hike is not particularly difficult, it took us just less than 40 minutes to get to the dam where the Silver Orioles are nesting.

With most of us not getting any good sleep the night before, we were finding the path much tougher than it should have been, but we managed in the end. The footpath cuts through some beautiful bamboo forest, I was expecting Chinese Bamboo Partridges to be abundant here but surprisingly we got none in the morning.

We arrived at the dam just past 7am. Just as everyone were still getting their cameras ready, a saw a bird flew in from the right side, it had dark head, grey body and a red tail! It was surely a Silver Oriole! It flew in and perched on top of a bamboo where I was able to confirm it as a female due to the streaky underparts.

Silver Oriole - Target achieved in less than a minute after arriving!

It was an incredible rush to be able to find our target species so quickly! A few minutes later the male also appeared and perched a little further away. This was the only perched view we had of the male during our time here.

For the next few hours we had good views of the female occasionally perching out on top of a bamboo, the male also flew past a few times. Views were not exactly close, even with my 500mm lens with 1.4x extender my image still needed a heavy crop, but Chun brought with him a scope, so we were able to get top views.

During our time there the adults never returned to the actual nest, which probably meant the young had already fledged and is somewhere nearby, sure enough Chun found the fledgling perched in one of the tall trees. The adults were feeding their young at the interval of around 15 - 20 minutes. Sightings of fledglings are not common, so we felt very fortunate to have been able to witness it! The adult brought in various of prey items, including caterpillars, cicadas and fruits.

Other birds in the area while we waited included a few Slaty-backed Forktails and a juvenile Plumbeous Redstart, although both were quite far away. We also had a Black Eagle which only showed briefly, another fairly scarce species throughout Guangdong, Liuxihe is likely the most southerly limits of this species we known of so far.

Indochinese Yuhinas were quite abundant and we encountered several flocks. Black Bulbuls were also in good numbers as expected, along with Chestnut Bulbuls, Grey Treepies and Hair-crested Drongos.

As we descended I spotted a Hill Prinia singing on an open branch, this is the closest encounter I've had with this species. Hill Prinias seemed pretty widespread in a few forest sites at Guangdong, including Gutian, but absent from Hong Kong. Whether this species can spread to Hong Kong remains to be seen.

Just before we got back to the restaurant, James spotted a flock of Black-throated Tits, a charismatic species of Guangdong's forests, relatively rare in Hong Kong where they are still seen occasionally. We had fairly good views of these cute birds.

We had a brilliant lunch at the restaurant, while we were there we also noticed a House Swift nest just under the terrace, which provided very close up views, in Hong Kong this species usually nest on much taller buildings, so it's unusual to be able to see their nest up close.

Our van departed at around 1pm, the way back to Shenzhen took slightly longer due to traffic, but we were able to get back to Shenzhen Huanggang Border at just around 4pm. It just shows such day trips from Hong Kong can be extremely productive, and open up a lot of relatively unexplored or under-birded areas in southern Guangdong. A huge thanks to Principal Kwok for organising the logistics for the trip, and it was extremely enjoyable with all the company of fellow birding friends.
