Endlings: Passenger Pigeon - Oct 14

 Obligatory disclaimer: real life sucks, so let us talk about ‘Endlings’, the Bizarre Beasts’ (BB) not-a-spin-off, instead. This episode’s topic – the passenger pigeon.

Some time ago, BB produced a promoting video of this event, where two women, Ms. Suta and Ms. Green, painted/colored a bunch of small plastic pigeon models and discussed the passenger pigeon’s Wikipedia article. It was not quite a scam, but it felt almost like one. This time, it is different – a completely new narrator, (and of a male gender too) discussed the passenger pigeon, why it died out and if it can be brought back.

…No, Colossal Biosciences (CB) are not behind it; this time, it is a different company, who claims that it will bring the passenger pigeon back, (in a manner of speaking) by 2032. Right now, it is October 2025. This means, that the company (Let’s call it RR), puts a ‘time stamp’ on its’ rewilding project – in 6 slash 7 years, few people can remember about RRs’ promise to bring the passenger pigeon back if RR chooses to go for the obscure approach… Interesting, and kind of suspicious.

The actual process of ‘bringing back the passenger pigeon’ is not too different from how CB plans to bring back the giant moa: CB plans to accomplish their project by combining the DNA of the emu and one of the tinamou species, while RR plans to combine the DNA of the passenger pigeon (it can be recovered, apparently), with that of its’ closest relative – the band-tailed pigeon – and inject the combo into the rock pigeon’s eggs…

As we discussed in the past, a tinamou-emu hybrid do not make a moa, especially a giant one. As for the pigeons, the passenger pigeon was a part of the Columbinae subfamily, the typical pigeons and doves in layperson’s terms, but it had its’ own genus and kept to itself; since at its’ peak the passenger pigeon numbered in millions, this was easy.

The band-tailed pigeon, meanwhile, belongs to the American pigeon genus that consists of 17 species, all of which are more closely related to each other than to the other birds, so what makes the band-tailed pigeon so special in regards to the passenger pigeon? The video does not tell us.

This brings us back to the passenger pigeon. It stood out from the rest of its’ pigeon and dove cousins by, well, the obvious. It lived and bred in bulk. It fed in bulk. It was usually in motion, looking for new food sources, (mostly grains, nuts, fruits, and the like). It was much more aerodynamic than many other pigeons – and it did not seek human cities to live in, unlike some other pigeons and doves. Pause.

…You take – intentionally or unintentionally – those features away, and the result is not a passenger pigeon, but some other bird. Pause.

There is no indication that RR intends to do this, but their process has the passenger pigeon DNA combined with the band-tailed pigeon’s, and perhaps the rock dove’s as well. There is no indication that the passenger pigeon’s DNA will be dominant, but if it will be…

…If the passenger pigeon DNA will be dominant, then the new bird will try to live like the extinct passenger pigeon did, which includes breeding and living in bulk. Will the 2030s North America be able to sustain this kind of population? Probably not without some massive landscape rewilding. Will the American society and government be willing to do this sort of massive landscape rewilding instead of building new urban centres? Probably not. And without large tracts of wild North American woodland, the new passenger pigeon will die out again, that’s the bottom line, unless…

…Unless it is being recreated not for rewilding purposes but for commercial ones, in which case the enthusiasm and the support for RR’s passenger pigeon project will drop. Listen, pigeons may not be as thoroughly domesticated as ducks and chickens, but they are domesticated and bred – for good looks, for mail carrier service, and for flesh and feathers too; we do not need another pigeon species/breed/GMO in the mix.

Let us pause and take a deep breath. The RR passenger pigeon project comes with options. It may work and we will have the new passenger pigeon – but we will not be ready for it and it will die out. It may sort of work, and will have a new genetically modified pigeon, which may act like the passenger pigeon, or not, for both the band-tailed and the rock pigeons belong to different genera than the passenger pigeon did, and both act – and look, and are built – differently from the passenger pigeon. Alternatively, the RR project will just fizzle out in the next 6-7 years, and we will have no new pigeon for our troubles.

Sigh. The narrator at ‘Endlings’ himself was rather sceptical of the passenger pigeon project; he tried his best to sell it to the audience, but he couldn’t fully do it. (The fact that he knew that most of us would forget about this video by the end of the week probably played a role too). The details of successfully bringing the passenger pigeon back to the U.S. are too many and he did not appear to have all of the answers – RR did not give it to him. Stop.

So, in conclusion. CB’s rewilding projects are exuberant and showy, but they do put CB into the spotlight, and CB cannot weasel out of this too easily. RR’s approach, on the other hand, allows them to do exactly that, and it is not an improvement over CB’s approach, sadly…  Looks like the rewilding projects/concepts/etc. in the West are in for some bad times…

Well, this is it for now. See you all soon!

CB and the dodo bird - Sep 19

 Obligatory disclaimer: real life sucks, and CB (i.e. Colossal Biosciences, if someone is confused), is intent on making it worse, apparently.

With the grey/dire wolves, they actually have something: three grey wolf puppies (Arctic wolf subspecies, most likely), with some biological & anatomical modifications that are supposed to make them more like the extinct dire wolves. Lately, the news of those three are rare, hopefully, then, they have not died on CB’s watch.

With the moa birds, CB ignored the fact that we still have samples of the moa birds’ skins, feathers, and the like, and proclaimed that they will hybridize the Australian emu with the South American tinamous, and release the new hybrids into the New Zealand wilds. This movie is of a dubious legality, but the fact that there is no guarantee that the resulting hybrid ratites will be viable supersedes that. Therefore, lately, the commotion around the would-be revived moa birds is dying down, and CB’s celebrity sponsors, such as Sir Peter Jackson, (who made the ‘Hobbit’ and LotR movie trilogies), are keeping quiet.

Now, (September 2025), CB is launching yet another proclamation: they recovered some sort of primeval pigeon gene that will allow them to recreate the dodo. CB just needs chicken eggs. Pause.

The dodo were pigeons. They were very specialized pigeons, they had their own subtribe, and their closest relative was the solitaire, another specialized flightless species that died in the 17^th century as well. Their closest living relatives belong to the pigeon tribe Raphini, whose members are relatively big and bulky, especially for flying birds.

…The Columbidae birds (pigeons, doves, etc.) come in two main varieties: sleek and streamlined, or big and bulky. The dodo and the solitaire were two extremes of the second variety, but their living relatives, such as the Nicobar pigeon and the crowned pigeons, also tend to be heavyset, though nowhere as extreme as their extinct kin was. Where do the chickens enter?

Nowhere, that is the thing. Chickens are gamebirds, members of the Galliformes order, completely separate from the aforementioned pigeons, doves and co.; the chicken and the pigeon may look superficially similar to each other, but they are just as closely related as the red fox and the hedgehog – i.e. not at all aside from the most basic ties. To use chicken eggs (and genes?) to bring back the dodo is about as logical as using elephants to bring back the Smilodon.

As for the primeval pigeon genes/genomes/etc. …The name alone is rather unfortunate and populistic – and also vague and generalized. CB gives no concrete guarantee that using this technique will bring back the dodo precisely and not something else entirely. A creation of a brand-new pigeon species, flightless or not, would be exciting, but it would not be re-wilding, not really. Rather, it would be playing God with life (with birds, to be more specific), and that is something else. Of course, whether CB would go this course, and not just take the sponsors’ money and run, is another question…

So, to recap: in a matter of years, in less than a decade, CB went from something respectable to half-frauds and half-madmen, who have done science in general, and rewilding in particular, a bad service indeed. To make matters even worse for them, there is no real source of dodo DNA – a head and a leg is all that remained of a rather enchanting RL species; pity that it could not co-exist with humans and their companions, (such as domestic pigs turned feral, and rats). CB – or anyone else – just would not be able to acquire dodo genes at all, and what they are offering instead may just suffer from a bad, populist name, or perhaps CB is just pulling a completely banal, ordinary, con. The future will show. Real life seriously sucks, sometimes.

This is it for now – see you all soon!
