Two shrikes

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 travel on work. When that gets too tiring then I relax by travelling for holidays. The holidays are pretty hectic, so I need to unwind by getting back home. But that means work.
