Bathing Oriental Magpie Robin

111112.jpg

In May 2008, Steven a.k.a. sharkspin photographed an Oriental Magpie Robin (Copsychus saularis) having a bath in a stream at Panti Forest Reserve, Johor, Malaysia (above). This reserve has been the Mecca of birders and photographers from Malaysia and neighbouring Singapore. The area is home to over 250 bird species, including several Sunda endemics and globally threatened species.

The Oriental Magpie Robin in this case was seen standing in the shallow water of the stream and vigorously ruffling its feathers (above). It also shook its wings and dipped its breast area into the water (below). Such actions allow droplets of water to get between the feathers and in the process, wash away dirt that collect on them.

After bathing, birds need to dry themselves immediately. Why? A wet bird may not be able to fly efficiently and thus can be quite helpless when confronted by a predator. Drying involves vigorously shaking itself to throw off the water droplets. The wings will also be shaken and flapped and the feathers fluffed.

After excess water droplets are got rid of, birds usually indulge in preening their feathers to keep them in perfect condition.

Bathing in streams and puddles is one of the ways birds maintain their feathers. Birds also bathe in the rain, on dew or water droplets collected on leaves after rain or from a hose during watering of the garden on a hot day. They also dust bathe.

Sunning is another method of feather maintenance, besides anting, although this latter method has not been properly observed locally.

Chestnut-bellied Malkohas sunning

“Chestnut-bellied Malkohas (Phaenicophaeus sumatranus) are considered uncommon, nationally near threatened, and globally near-threatened species, so it is with great luck that I was able to come across two birds in the same morning. I believe one of them was a female, however based on my fleeting observations of the two I am not able to tell.

“The morning was blessed with bright sunlight, and the two birds were obviously enjoying having a sunbath. And with their dark coloured feathers, they would be able to gather heat from the sun with greater efficiency. It also was suggested that they may be anting, however on examining my pictures, could not see any evidence of it.”

Sunning is another method of feather maintenance, besides water and dust bathing, preening and anting. In sunning, birds adopt varied postures. Both or one wing may be extended and the tail feathers spread out. The bird usually lies on the hot ground with its head lowered and tipped to one side. It may remain motionless for some time, but not in the case of these malkohas.

There are two earlier posts: One shows a malkoha sunning on the ground but the observer was not able to get near for a close-up shot, unlike the present encounter. The other shows malkohas sunning themselves on the branches of a tree.

We are more familiar with sunning by cormorants and anhingas, not so with other birds…

Date of observation: 13th May 2008

Spotted Dove sunbathing

11119.jpg 2227.jpg3331.jpg

Lately, a pair of Spotted Doves (Streptopelia chinensis) have adopted my garden, visiting a few times a day to forage and to sunbathe. Initially, I managed to see only one large bird lazing on the driveway, raising its wings to soak in the sun (left). I only noticed it when I walked out of the house and th bird noisely flew off into the garden. Besides the characteristic loud flapping, also made by other pigeons like Pink-necked Green Pigeon (Treron vernans), my attention was also directed to its large pair of wings and tail feathers as it flew off.

I used to surprise the bird a few times when it was foraging on the ground of my garden. Subsequently I became more careful. The bird meticulously searched the ground, foraging for up to half an hour at a time, pecking the ground whenever it found seeds, ants and what not before moving off.

During hot periods when the driveway is heated up, it will lie on the tiles, spreading its wings upwards to the sun. It would appear that this form of sunbathing is characteristic also of the Peaceful Dove (Geopelia striata), previously known as Zebra Dove.

One day, I found a pair perching on the top of my gate. This was the first time I have seen the two birds together (below).

Yellow-vented Bulbul bathing in the rain

11112.jpg11110.jpg

Not all birds take shelter once it rains. Not this Yellow-vented Bulbul (Pycnonotus goiavier) anyway. It perched on a branch shaded very lightly by the leaves of the curry bush (Myrraya koenigii). The droplets of rain fell on its plumage. The bird shook them off and fluffed its feathers.

It was obviously having a bath.

This went on for about four minutes and the bird moved from point to point. And all the time it was enjoying the rain.

Then the rain stopped and the bulbul moved to an exposed branch, stretched out fully and sang a few of its short-syllable song. It then flew off.

Bathing is one way of keeping the feathers in top form. Preening, anting, dust and sun bathing are other methods.

Oriental White-eye taking a bath

2226.jpg11118.jpg

Harshit Singhal is a young birder from India who sent in this account of his observation on 15th March 2008.

“I have kept a 3 inch deep bath tub on the ground just besides the 
guava tree (Psidium guajava) and birds such as fantail flycatcher, Jungle babbler (Turdoides striata), Red-vented Bulbul (Pycnonotus cafer) have often been seen bathing in it.

“But on 10th March, an Oriental White-eye (Zosterops palpebrosus) perched on the guava tree and then hesitantly moved to the top of the bath tub (left below)

“It appeared very vigilant and cautious and after making sure that there was no enemies 
nearby, it plunged into the water and took a fanatical bath. After 
flapping its wings four to five times, it flew to the nearby Chakotra tree (Citrus maxima) 
and started grooming its feathers.

“It was a fascinating sight for 
me as I have read in field guides that white-eyes are completely arboreal and do not descend on the ground.”

It may be arboreal but the bird needs a bath and it needs to come to the ground for it.

"You can know the name of a bird in all the languages of the world,
but when you're finished,
you'll know absolutely nothing whatever about the bird...
So let's look at the bird and see what it's doing - that's what counts.
I learned very early the difference between knowing the name of something and knowing something."

Nobel Laureate Richard P. Feynman (1918-1988)
