eurasian curlew swallows a stone @ SBWR-26Sep2015

The lone Eurasian Curlew amongst the whimbrels did something strange in that it swallowed a small pebble. Perhaps this is to aid digestion in some way.

Why would a bird swallow a stone? and what is a gastrolith? ...and what possible link could this have to dinosaurs?

crested goshawk @ JEG-Aug2015

Walking along the nature trail at Jurong Eco Garden, i thought i had spooked a nightjar resting close to the trail. Seeing it in the shadow of the canopy, i realised that it was not a nightjar but something else. The bird was sitting upright and looking about actively. The resident laughing thrushes were making a lot of noise likely because of the prescence of the crested goshawk.

The raptor flew to another branch closeby where it received a earful from a racket-tailed drongo which was also not happy about its prescence. It finally flew off to another set of branches followed by the drongo.

black bitterns @ SBWR - June 2015

Looks like the black bitters are still around at the Sungei Buloh Wetland Reserve (SBWR).

There might actually be more than two black bitterns. The mizzle (miserable drizzle) added to the difficulty in spotting anything. More so for a well camouflaged bird. I only noticed the first two black bitterns when one took off from one far corner of the pond and flew towards another which caused the second one to fly off too and both landed in a sea hibiscus bush at the edge of the pond. The second one disappeared behind the branches and leaves soon after landing but the first sat exposed on a branch for a few moments before it too decided to seek cover further in the bushy thicket of sea hibiscus shrubs. With both birds well hidden, i thought that was the show for the morning. Then, after about 5 minutes, i saw a little movement on the marshy ground in front of me and realised that it was a black bittern out hunting in the rain. I had not observed the second bird flying back to roughly the same spot it must have been at earlier. This could be a third bird (or maybe it was the second bird sneaking back to the same spot.).

Despite the mizzle, it continued its extreme slow motion hunt for small fish in the shallows. The drizzle did not seem to affect it much at all. However, the constant splashing of raindrops onto the water surface might have made spotting fish near the surface of the water more difficult for the bird to spot prey. The fishkill success rate was much lower than what i had observed the previous weekend when i had seen a black bittern enjoy easy fishing in bright sunny conditions.

With its deceptively slow steps and slow-motion like movements, one would not be wrong to assume that this bird was not capable of fast movement. Nevertheless, when it did lunge for a fish, the action was incredibly fast. With its very dark almost jet black coat, this bittern blended in very well with the foliage at the pond. Perhaps this is why spotting this bird is so difficult.

black bittern @ SBWR - June 2015

I had seen this flash of black flying past occasionally over the past few months but was fortunate to see it in the open and stationary finally on 01 June 2015. I'm informed that this is a rare spot for this time of the year as this bird is an uncommon migrant and the migratory period ends in March-April each year.

However, i soon realised that there was not one but two black bitterns (both with adult plumage) within about 5 metres of each other. Perhaps these have taken up permanent residence in Singapore. Even a dragonfly thought it was ok to land on the videoed bittern for a short time. I guess the top of the bittern was the safest place to be for a dragonfly. The bittern shook off the unwanted tenant and continued with its morning breakfast hunt for a good many small fish.

grey-headed fish eagle squawk & flight @ SBWR - Feb 2015

Was fortunate to come across one of Singapore's endangered birds, a large bird of prey no less, at the Sungei Buloh Wetland Reserve. It was a breezy February afternoon and the bird let out a characteristic squawk (at about 00:17). This, i'm guessing, was a territorial call of some sort. There was unfortunately no return call from a distant corner. There were other raptors resident in the area, namely the more commonly seen, and largest raptor in Singapore, the White Bellied Sea Eagle and also the ubiquitous Brahminy Kite. It waited for about a minute and a half before calling out again. (I had changed positions to find a better vantage point).  It was finally forced off its perch by the strong February winds and it flew off to find another tree where perhaps it would have more luck with a return call.

The clip from 01:46 shows what is possibly the same GHFE taking off from another tree. 

I hope this critically endangered species survives endangerment and thrives in Singapore. As a fish eagle, it does require a decent pool of water well stocked with fish and sufficiently tall trees to build a nest in. It needs an ecosystem. Can Singapore maintain this beautiful large raptor for the next generation? We need to maintain our forested areas near water bodies.
