Watchin them birds on the street

My first falcon sighting. To chance upon a Shikra, in the middle of urban Delhi, is surprising. Thanks to the drifter day, I got to notice it, perched on the branches of the tree next to my balcony, feeding on carrion. A long observation ensued. The bird was not nervy to my presence, as I had assumed. We both checked each other out aplenty. A very curious squirrel kept pestering the bird, while it lounged on its breaks between the feeding cycles.

PS: Shikra derives from the word "shikari" or hunter, as it is trained and used in hunting by the falconers. It is comparable to a German Shepherd (of domesticated birds world), as in being a utility bird that could fetch game for other more prized birds.


It also turns out that Shikra is not a falcon, but a type of hawk (also called "little banded goshawk") - an Accipiter. It probably was a female, "her" spots match more of whatever females I could find on Google for a confirmation.

The shikra is a small raptor (26–30 cm long) and like most other Accipiter hawks, this species has short rounded wings and a narrow and somewhat long tail. Adults are whitish on the underside with fine rufous bars while the upperparts are grey. The lower belly is less barred and the thighs are whitish. Males have a red iris while the females have a less red (yellowish orange) iris and brownish upperparts apart from heavier barring on the underparts. The females are slightly larger.

Armchair ornithology FtW. This is why we need surviving canopies in our residential areas.

ghoom for porcie

This is Major Tom to Ground ControlI'm stepping through the doorAnd I'm floating in a most the peculiar wayAnd the stars look very different today

The stars ended up looking very different today, indeed. The moon was there too, right under the eye. And there was a fleety-floating moment, too. It all started with me and baby bro stepping through the door.

Me and S went out on a nightly ghoom. Since being floored running into the Hystrix Indica (or Indian Crested Porcupine), I have revisited the place in anticipation of catching another glimpse of the wonderful pair that I came across on my last visit ~20th.

We ambled up till Ak. S was busy with his camerawork. Having OTL in crazy mode has pushed her into weaning me away from the (only?) two things I've loved in the two years - her and the cameras; ah, damn the life I live. Night in the Indian forests, however, is engaging, so I didn't mind not having a camera. Beyond Aluk, we merged into the forests downhill.

We had radios (MR350s) on us, and split as we went down. I took a trail higher up, and S about 40m lower. Being split meant we can do a sweep more effectively. Good decision to get the radios, but a bad one forgetting a pair of torches (only got one).  The radio helped cover some embarrassment, its built-in lamp coming to the rescue to whoever didn't carry the torch.

10 minutes in, and S spots a pair of eyes. There's a small ravine connecting him to me, so I had to skirt around it as S asked me to wind my way back. There, about 40m down yet another sharp ravine, were a pair of yellow-orange eyes, looking back, as if trying to figure out these intruders. It seemed a civet to me, by the range of its head motions, its size, and its tapetum lucidum - that layer which reflects a distinct hue for each animal. S and I decided to split again, me coming at the creature from South and S from West. We got close, but the creature ultimately got alarmed and bounded away.

We went down deeper, but got nothing else, though we did hear a coupla things breaking, to perplex us, as much as it did to the origin of those sounds. After having done enough for the evening, we took a short break. Then back up, onto the road, then home. Once out on the road, I didn't stop my elevation gain, and climbed all the way to the ridge crest. The night sky was a complete picture today, thanks to no clouds.

platypus awesomeness

Platypuses are awesome, because

  1. it is an incredulous evolutionary abnormality, that was considered a hoax when first reported.  it was thought that somebody had sewn a duck's beak onto the body of a beaver-like animal.
  2. the plural of platypus is platypodes (not platypii)
  3. they are monotremes i.e. lays eggs instead of giving birth. monotremes ~ monos + trema which means single holed, which refers to its cloaca (and cloacal reproduction).
  4. a group of playtypodes is called a puggle
  5. the most famous species of platypus known is the duck-billed platypus. strangely, it is the only species of platypus known as well.
  6. they are also one of the few venomous mammals. the male has an 'ankle spur' on his feet (much like cowboy spur) that is connected to crural glands which produce venom, that works by triggering oedema, that could kill smaller mammals (like dogs) and incapacitate humans.
    some other venomous animals are the European mole, the Eurasian water shrew, and the hedgehog (which exhibits a behavior called self anointing where it smears its spines with poison from a frog's glands, thought it is debatable whether it is for defense or sexual arousal in partners).
  7. their tails work as fat reserves. that is an amazing adaptation. (more amazing, i can imagine, would be if they could mix it with caudal autotomy, which is what lizards do when under threat, making it like a sacrificial gesture to the predator god).
  8. it hunts inside the water, with eyes, nose and ears completely blocked. what it has done to overcome this handicap is unbelievable. it has developed electrolocation. its beak can be imagined as a flat radar scanner, that is lined with rows of electroreceptors. it detects tiny muscle contractions in its prey, providing all its input data in this form, continuously scanning the water for more calculation (feed me data!) through characteristic side-to-side motion of the head.
  9. being a mammal, it feeds its newborn milk. but this milk comes not from teats, but through skin pores that give out milk. this milk collects in grooves on its abdomen, where it's lapped up by the newborn. that is a new solution to a regular mammalian problem.
  10. mammals, ordinarily, have 2 chromosomes. platypus has 10 chromosomes.
  11. no gene has been identified with gender determination in the the platypus.
  12. the platypus features in an indigenous Australian story, where the major animal groups, the land animals, water animals and birds, all competed for the platypus to join their respective groups, but the platypus ultimately decided to not join any of them, feeling that he did not need to be part of a group to be special. story of my life!
