Three shrikes and you’re out. No birder will tell you this, but it’s true. I’ve never seen more than three kinds of shrike in a morning of bird watching. Last week’s outing to Bhandup Pumping Station was no exception. I heard a beautiful birdsong, one that was not familiar from the past six months of patient study, and found that it came from this long-tailed shrike (Lanius schach, aka rufous-backed shrike).
I’d only heard the shrill harsh call of this bird, so common across India. That shriek gives the group its name. But this was a song. Quite different, and more enchanting. Why was it singing when the mating season was past? It was answered by other calls. So perhaps this was a territorial call. I recalled a paper I saw a month ago which said that bird calls had become more complex in the quiet of the anthropause. One of the results was a decrease in aggression among city birds, because the more complex songs seem to better convey meaning about territory.
A little later I walked down a side path where three boys went racing past me with bikes (and unmasked, perhaps because they were outside the gaze of parents). In the quiet after they left I looked around and spotted a great grey shrike (Lanius excubitor lahtora). This was renamed two years ago, and some would recognize it by its older designation of southern gray shrike (Lanius meridionalis). The photo shows it in a characteristic high perch. The perch seems to be an important aspect of its territorial behaviour.
These were all the shrikes I saw that day. I never even reached the upper limit of three.
I admire your patience, IJ, and your ability to listen and track down these intriguing birds. It’s interesting what you wrote about their high perch.

Thank you, but you ascribe qualities to me which others have in much greater measure. Compared to most birders I’m a rank amateur.

Listening to bird calls would have been so pleasurable especially in these unpleasant times.

It was nice to wake in the early morning and listen to the calls changing with the hours.

Very informative post, and noteworthy that bird songs have changed with the ‘quiet’. A bonus! Though some birds are unsure of coping with the quiet. You can’t please everyone.

Thanks. In either case, it is interesting to learn how much we inadvertently affect the world around us

Last year I attended several in-the-field Warbler photography workshops. The instructor could tell the different types of Warbler calls and whether they were signalling “found food” or when one male bird invaded another male birds space. It was fascinating.

Yes, amazing how much information there is in bird calls. I hope to learn more; it’ll be an experience to walk through woodlands and really hear what is going on around you.

I find it really interesting that birds may have changed their calls as the quiet around them has grown – pretty fascinating I.J. That’s quite a tail on your closing bird image!
