Cavalock and The Cuckoo Bird Switcheroo Syndrome

Another blog post, another Japanese beer shot. Got this at Raffles City Marketplace supermarket. Haven't drank it yet. Says it contains 'hints of cypress and lemongrass', I have always had a thing for lemongrass so I'm hoping this is something that I'll like as well.

One of the things that I have kinda neglected doing during the lockdown and this post lockdown period is my notebook journaling and calligraphy. I was really into it and I was taking it out with me to write stuff, then the lockdown happened and I kinda lost the mood to write bout stuff since ... nothing much happened anymore! Well, I finally started journaling again and of cos the first thing I gotta do is fill up my empty fountain pen. Now I bought this demin color ink on a whim a while back and it turned out pretty good. 

So me Dad was out taking more wildlife pix recently and found this rather interesting pair. What you have here is a smaller tailorbird feeding a larger baby cuckoo bird. So what happened was a mother cuckoo laid an egg in the tailorbird nest and then flew away. These are known as 'parasitic cuckoos'. 

Female parasitic cuckoos sometimes specialize and lay eggs that closely resemble the eggs of their chosen host. Some birds are able to distinguish cuckoo eggs from their own, leading to those eggs least like the host's being thrown out of the nest. Parasitic cuckoos that show the highest levels of egg mimicry are those whose hosts exhibit high levels of egg rejection behavior. Some hosts do not exhibit egg rejection behavior and the cuckoo eggs look very dissimilar from the host eggs. Other species of cuckoo lay "cryptic" eggs, which are dark in color when their hosts' eggs are light. This is a trick to hide the egg from the host, and is exhibited in cuckoos that parasitize hosts with dark, domed nests.

So the dumb tailorbird didn't know any better and has been raising an illegitimate child every day ever since. Anyway both birds have since left the area and hopefully the poor tailorbird isn't still feeding the cuckoo bird.
