7 February 2011: mainland Penang ricefields

Had another shot at tracking down the Steppe Eagle today, this time with Aun Tiah of the Raptor Study Group.

We started off at Permatang Nibong, where one adult Greater Spotted Eagle was roosting on the favourite pylon. The Peregrine pair were still on pylon 319, and another could be seen distantly perched on another pylon.



Here's the pair.





A close up of each bird. Compared to the one at Sungai Dua (see the photos on this post), these are noticeably darker above, lack the pale forehead, have broader moustachials, a peach wash to the underparts and heavier spotting on the belly and flanks. These differences seem to accord with what we could find in literature about the differences between the japonensis and callidus subspecies. Could it be that these birds are japonensis and the Sg Dua bird is callidus? They all seem in fresh plumage (so the differences can't be attributed to wear). I'd be interested to hear views on these birds.

We spotted some mistnets with dead birds in them in the distance, so started walking toward them. As we did so, we regularly flushed Zitting Cisticolas left and right out of the paddies.



But it would be a mistake to assume that everything that comes out of the rice is a Cisticola! Especially early in the morning, when skulking Locustellas come out to sun themselves, as this Pallas's Grasshopper Warbler did.



"PG Tips" as we called them in my UK twitching days (not that I ever saw one in the UK!) start singing early in the year while still on the wintering grounds. The song and call are quite distinctive, and best heard early morning.



I moved to get closer to the bird. The light was less favourable so I didn't have much hope for these pics, but actually I find the effect of the strong backlighting quite pleasing.



This worn individual is quite well-streaked on the breast and has lost its white tail-tips.






















Flashing its undertail at me before diving into cover!

It's quite amazing how the light affects the appearance of the plumage of this bird. Had I not seen it in good light (first two pics) I might have been wondering if this was a Middendorf's Grasshopper Warbler, as it looks relatively unstreaked above in the backlit pics. Before you ask, it's definitely the same bird - and even the same stalk!



An adult female Pied Harrier gave us brief views. The rear flanks are distinctively white and unstreaked.



The nets had 5-6 birds in them, some dessicated by the heat to the extent that they were unrecognizable.



A female Greater Painted-snipe.






















Cinnamon Bittern.






















Barn Owl.

This illegal practice is still widespread over many rice-growing areas. The rationale is apparently to deter birds that might eat the paddy, although the mesh is large enough to let munias, the main crop-feeders, pass right through.

We moved onto Sungai Dua, where the juv Steppe Eagle had been seen. We had another good view of the Peregrine there - our 4th for the morning, and on our way back toward the road, came across this sitting in a field.







A superb juvenile Greater Spotted Eagle.





It didn't stay perched for long.



Getting some unwanted attention from a local Brahminy Kite.

So still no Steppe Eagle on my third attempt. In the afternoon, we headed to Perak to watch a large harrier roost at Ulu Dedap. More in the next post!

4 and 5 February 2011: Sungai Dua, mainland Penang

I've spent the last two evenings at Sungai Dua ricefields trying to track down a Steppe Eagle seen by Hakim. So far, no joy, but plenty of consolations!



Stubble burning - not good for our atmosphere but it brings in the birds - swiftlets and swallows to feed on the insects and raptors for the rodents.

Black and Brahminy Kites were there aplenty, but what I wanted to see was aquilas. I missed on here yesterday, but this adult Greater Spotted was present on my arrival today.



I was puzzled by the white patch on the throat till I realized that it was caused by under feathers exposed by an extremely distended crop. The bird had obviously just swallowed something large!



That might explain why the bird had its beak open most of the time.





You can get an idea of the size of the crop from a side-on profile.



Had I arrived 5 minutes later I would have missed it altogether - it was probably off to find a quiet spot to digest its meal.



This Peregrine was present both days, sitting on the same pylon.



It was an immaculate bird in perfect, fresh plumage.



Keeping a wary eye on me!



Watching swiftlets.



And checking out Hakim!



All these pics and the video were taken with my new canon S95 through the telescope at up to 60x magnification. I'm very happy with the results!



It had a fly around once. In flight a grey background colour to the underparts was noticeable, contrasting with the white throat.



Flypast.



Comin at ya! The last view of a Peregrine many birds ever see!



Returning to her perch. The alula (the raised feathers at the carpal joint) is used for braking.



At dusk today, while I was waiting for the Great-eared Nightjars, this juvenile Peregrine flew past. It looks as if it had fed well!



We got brief views of a juvenile Pied Harrier yesterday.



And this fine adult male Eastern Marsh put on a good show both evenings.



These are last evening's pictures.



This evening it was closer...



...till it spotted me!



Great light!



A couple of resident Black-shouldered Kites - this is one of the adults.



And one of their offspring, already quite mature.
