The Migrant Birds of Chuping Grassland Feb'16 - PART 2

There are many things in the universe which science has yet to find an answer - like why some people do not like to put on the indicator light when changing lanes? or why it appears that Singapore has more rare birds visiting them frequently? or perhaps why all planets are round and not square or triangle in shape? When science can't find an answer to a phenomenon then the spiritual perspective will usually fill the void. 

Unlike some migrants birds which may have took off as early as February, some of them have preferred to stay a little bit longer - either due to the reason that they have arrived later during the autumn migration or perhaps they are filling their fats and strengthening their flight muscle before embarking their arduous journey home. Here are some of the migrant birds which are still around in mid February:

Common Kestrel (Falco tinnunculus) - female

What a beauty ! Basking herself in the glory of the early morning sun rays. 

Eastern Marsh Harrier (male)

This is what happens when you have forgotten to change the aperture in your camera otherwise it would have been a splendid photo.

The same bird as it flew further away.

Pied Harrier (female)

She is scheming the weeds below for her first morning meal.

Common Stonechat / Siberian Stonechat (male)

Presently there are 24 known subspecies of stonechats (HBW alive). Most of them i believe were based on geographical variation. Out of the 24 subspecies, only two are said to occur in Peninsular Malaysia i.e Saxicola stejnegeri and S. przewalskii. No worries as long as you call them either a Common Stonechat or a Siberian Stonechat nobody will laugh at you.

Did you just said i am from Siberia?

Here is another male common stonechat which was seen not too far from the first one. This one appears like having some new and fresh feathers sprouting out near its rump.

How do you differentiate between a male Oriental Pipit and a female Oriental Pipit? Well just look at their legs. This one i think is most likely a female.

This one appears to have a longer snout and beak but since i have not mastered the features of a Richard's Pipit, i will just named it as an Oriental Pipit as well.

Brown Shrike

This shrike has also yet to depart for home.


Here are some of the resident birds which are equally stunning.

Purple Heron

It stayed motionless like this for close to 10 minutes but eventually it still missed catching the prey.

Little Grebe

They are a pair i believe.

Female Pink-Necked Green Pigeon

Its not easy to  photograph them in flight. This one was just one lucky shot.


Here is one which i have not seen before - a leucistic Yellow-Vented Bulbul !

Despite its condition, it still retains its yellow vent. There have been  a few reported cases of leucistic Yellow Vented Bulbul in this region and i believe Wong Tsu Shi has also photographed one in Sabah. Why is this bulbul species are so prone to deficiency of melanin ? You might just need to ask the bird scientist.


HAPPY BIRDING !

The Migrant Birds of Chuping Grassland - Feb'16 - PART 1

Spring is in the air and it marked the start of an epic avian migration ever witnessed in this part of the hemisphere. By the time you read this post, the raptors of Pulau Rupat have already started their journey en-masse just like some of the wildebeest of Tanzania albeit in a slightly smaller scale. What triggers them (the birds) to start this epic journey? Do they follow the same route back to their breeding grounds? Are they all migrating at the same time? These are some of the intriguing questions which are often posed to the scientific community. 

As a self-trained birdwatcher, i have always tried to find an answer to those questions. Perhaps i could find some of them in this vast grassland.

Oriental Honey Buzzard (OHB)

From its features (greyish head and dark brown eyes), this OHB is certainly an adult male orientalis. (common morph). There were two of them and they were flying just above the tree tops and heading towards east. Question: could they have been heading for 'home' or are they just some resident OHBs? To answer those questions, there are two information leads which you could look for. Firstly the migratory form of orientalis are reported to be generally paler while the resident bird has darker underside. Secondly migratory raptors usually fly higher. However i could be wrong as some migratory raptors are known to "overnight" in their staging areas while waiting for the right time to continue their journey.

Unlike the above OHB, this forked-tailed swift (Apus pacificus) was heading north (towards Thailand) instead of eastwards. 

Apus pacificus

There were 5 of them but this one flew closes to me. Some reports have indicated that A.cooki is more common in open areas and in northern Peninsular Malaysia but i have identified the above swift as an A. pacificus based on its broader white rump band.

The same bird with a visibly large white band on its rump. Looks a bit like a tomahawk cruise missile.

Just like the above fork-tailed swift, these Oriental Pratincole (Glareola maldivarum) were also heading northwards.

Oriental Pratincole

Although there have been breeding cases reported in Selangor, Kelantan and Kuantan in the past (Allen J & Pearson 2012), it will be quite difficult to determine whether these birds are actually resident birds or migrants. Perhaps a satellite transmitter can be placed on one of them to track their movements. If they were indeed migrant birds then they could have flown from as far as Indonesia and Australia.

I saw a total of 15 birds in a span of 10 - 15 minutes. They did not appear all at once but mostly in a single file, sometimes two and at the most 3.

I believe its much easier to differentiate "pratincole" while they are in flight rather than when they are aground. The absence of the white trailing edge to the wing should eliminate them from a "Collared Pratincole" (Glareola pratincola). 

Note: they were once included in the "wader" category but now they are more or less a distinct species.

Most of them are already in their breeding colors - red-bill base.

From this anecdotal observation you can see that the above three species of birds (if they are indeed migrants) have chosen different routes in their spring migration. Does that also meant that some of them uses the land route while some would prefer the sea route?

More answers can perhaps emerged from the next few posts.
