I hear two male Red-vented Bulbuls are singing from tree tops in the morning these days in and around my home garden. They utter a sequence of ‘ginger beer’ song on and off during their singing sessions.
The Red-vented Bulbul (pycnonotus cafer) is a familiar garden bird and very common everywhere in the country. Male Red-vented Bulbuls sing quite pleasant songs during the main breeding season of the birds in the country, which is the first half of year, although this bird nests almost throughout the year. Song repertoire of this bulbul is quite varied and consists of many songs with pleasing sounds. Amongst these ‘ginger beer’ is one distinct song uttered in sequence with other songs in the repertoire.

The ‘ginger beer’ song featured below was recorded by me in May 2008 in my home garden.
G. M. Henry in his classic work on the Sri Lankan birds ‘A Guide to the Birds of Ceylon (1955)’ writes this onomatopoeic name ‘ginger beer’ under the account of Red-vented Bulbul (pages 19-20) to describe this distinctive song type of the bird.
The Asian Koels (Eudynamys scolopaceus) in my home area are still singing. They started singing in February and still continuing it. Males start to sing well before dawn and going on with it almost throughout early part of morning, and then sing on and off during the day time. Then frequency of singing increases again by evening.
They were singing frequently almost throughout the day time during last few months, and in that time they were also singing in some nights. There are about five males are singing and several females are calling within the area which I can hear.

I still did not notice the Jungle or Large-billed Crows (Corvus macrorhynchos) are attempting to nest in this area. But, about just quarter of a kilometre away along the Highlevel road there are few pairs of House Crows (Corvus splendens) started to build nests on electric and telephone posts. However, I wonder whether the females in my home area will ever get a chance to lay eggs in these House Crow nests as there are already other koels are singing in the vicinity of these nests.
Besides the males’ very distinct and familiar song they also sing another type of song time to time, of which the purpose appears to be also for advertising their presence to the females.
The familiar song of the males featured below was recorded on 03rd May 2012 in my home garden. It is the sound which connects the koha (the Koel) with the Sinhala Awrudu (the Sinhala New Year) in April.
The other song of the males featured below was recorded on 12th May 2012 in my home garden. In this recording other koels in the area are also heard, including the call of the females described below.
Females have a very different vocalization in contrast to the songs of the males. Males also utter the same call on and off, and it is the only vocalization heard from both sexes during non-breeding season when the males do not sing.

At times in the morning I now hear up to four male Red-vented Bulbuls singing from their regular ‘song posts’ within vicinity of my home garden. Two of them sing from their regular tree tops (i.e. ‘song posts’) of two immediate neighbouring gardens and the other two from their ‘song posts’ in the gardens further up. I recorded few song repertoires of one of the males in close vicinity and parts of three repertoires are featured below showing some of the different songs that these bulbuls sing during their breeding season.
Sound track below features a part of repertoire with about four different types of songs. Singing of one of the distant bulbuls can also hear in background of this track.
Sound track below features a part of repertoire with about three different types of songs including the ‘ginger beer’ song at the end (the last two songs), which I described in my last posting in the blog.
Sound track below features a part of repertoire with about six different types of songs including a song sounds ‘sweet potatoes’ at the end (the last two songs), as G. M. Henry names this song type under description of vocalization of the Red-vented Bulbul in his classic book on Sri Lankan birds ‘A guide to the Birds of Ceylon’ (1955).

A male White-throated Kingfisher (Halcyon smyrnensis) has been singing almost every day from tall tree tops in and around my garden since early last month (March). This male was trying to attract a female while establishing a territory for breeding. Its regular ‘song posts’, of which it sings at each post for a considerable time, are fairly wide apart but most of them can be seen easily from my garden.
I observed a female came on and off to one of the trees where the male was singing from and started displaying to male with its wings spreading out showing distinct white patch in the wings.
I assume the male has now paired out with the female and nesting somewhere within the territory which male has established as now frequency of singing of the male has reduced a lot. The White-throated Kingfishers do not sing like this outside their breeding season.
Sound track below features song of the male kingfishers, recorded on April 29.
In the morning yesterday I heard calls of mobbing Red-vented Bulbuls from direction of my backyard and inspecting on that I came across a Collared Scops owl (Otus bakkamoena) roosting at a fairly high place on a Bread Fruit tree in the adjoining garden. It was sitting under a clump of large leaves of the tree and two pairs of Red-vented Bulbuls mobbing at the owl while uttering their loud scalding calls. The four bulbuls were later joined by a pair of Purple-rumped Sunbirds (Nectarinia zeylonica) for mobbing the owl.

Sound track below features scalding calls the mobbing bulbuls, and also scalding calls of the Purple-rumped Sunbirds towards end.
I heard the bulbuls were mobbing the roosting owl time to time almost throughout the day. This was not a regular roosting place of the scops owls in the area, the pair in this area roosts in the day time at some other place in their territory. At the late evening I stood in the vicinity of the Bread Fruit tree equipped with my sound recording gear expecting the owl may call at dusk before or after it leaves from its roost. But just at dusk I suddenly heard call of a young scops owl from some distance away. The young owl kept calling for some time and then flew and landed on another tree nearby me. Although the adult owl didn’t call the young one kept calling and it was soon joined by another calling young owl which flew in from a different direction. Both young birds kept calling for some time before they flew away.
Sound track below features calls of a young scops owls. A hissing sound of the juvenile is very much different from the calls of adult birds.
