Outdoor cats cause so much damage it’s awful… Even when there are laws about it owners don’t listen and keep their cats outside and wildlife pays the price. And when native animals in Australia and New Zealand get attacked they don’t have any defences to the bacteria in their mouthes and under their claws so if you do find an animal who survived a cat attack they will need a really intense run of antibiotics to survive. Like we were told in the caring for orphaned birds workshop that when you see a bird blown up like a balloon (from a ruptured airsac) the main worry is that it’s from the pinpoint wounds of a cat’s claws and the bacteria that comes with that is often fatal Also off leash dogs on beaches where they aren’t supposed to be mess with migratory birds not letting them rest and kill fairy penguins in Australia too

[@NZBigfoot]

As a NZer... I live rural, and in the last 20 years have owned 13 cats, and at one point within that period of time we had around 10 cats at once... currently where down to 3 as they grew old and passed on. Our property has ALOT of birds, and yes... our cats catch and eat 'alot' (maybe 5-10 a week in summer back when we had 10 cats at once), although half our cats ignored birds entirely, and only 3 of them were prolific bird hunters. But heres the rub... and something the anti cat brigade seem to ignore... Our cats ate, in terms of birds, mostly finches, sparrows and black birds or starlings. Species that are in no way endangered or being impacted by cat predication... the bird species however our cats caught the most of were wax eyes, and lets just say wax eyes breed like rabbits, our fruit trees would be decimated by them yearly. Im talking one fig tree having 50+ of them at once flying around in them... after that it would be the sparrows and finches, and usually it was the fledglings rather than adult birds (still didnt make a dent in the overall sparrow population locally)... our property still has just as many birds (native and non native) on it as it did when we had more cats, and in terms of our area (on the outskirts of a rural town) the surrounding properties all have at least a cat or two each themselves... so cats per square km is high and the bird population is just fine and dandy. But you know what is the biggest prey animal my cats catch and kill out numbering any number of birds they catch... rats (and mice)... which are the REAL issue for our native birds, besides the stoats/possums and dogs off leashes due to irresponsible owners. Cats compared to most of the other introduced predators in NZ are way down the bottom of the list, especially when you actually look at what the cats are actually catching in terms of species... dogs on the other hand, they kill way more actually endangered species than any cat does. And rats, hell... get rid of the cats in NZ and you're looking at a Ratpocalypse within 6 months minimum THAT will really screw NZ bird species over. No animal has defenses against cats mouth bacteria, its simply a part of how a cat kills its prey a cat can find and eat the bird later when it finds its body, nice and efficient, you loose a catch but get to potentially find it again later... then again ive seen birds die from fright, their shockingly fragile lifeforms. Do i like my cats killing birds? no, but they are a predatory animal who is born and evolved to hunt... its what they do, and if someone says oh woe is me, but what of the birds... ill tell them this... Ever watched miner birds pulling baby sparrows out of their nests dropping them then eating them? Ever watched a Tui kill another Tui in a fight over territory? Ever witnessed a female sparrow being literally gang (well you know) to death by 15+ other male sparrows?... i have, quite a few times... birds aint saints.

Yeah, it's not the only species.

I keep my dog inside and in the yard. I don't let my boa constrictor roam. I keep our rabbit behind a fence. My chickens lived in a coop and run. Why is it acceptable to just let cats go around and kil things? If I wanted to take a three toed box turtle or a hognose snake from the wild and keep it as a pet, it would be super illegal and considered poaching, even if I bred them and returned a hundred hatchlings to the habitat. But it's totally fine if someone's industrious feline runs around and wipes out hundreds in a year or so, rendering them locally extinct.

[@cuttlefishonfire7502]

Speaking as someone with indoor cats, it's so weird! Like, if I let my cat outside it risks getting hit by a car, or eaten by predators, as well as causing damage to the environment by killing wildlife! Why are so many other cat owners just okay with this?! I once saw someone talking online about how indoor cats were less happy and it was bad to keep cats from their natural habitat, and this person was Brazilian! Domestic cats natural habitat is not in Brazil, it's not where I live in the US either, cats were domesticated in west Asia, and even then that was many thousands of years ago! Cats natural habitat is not in the wild they are domestic animals! In the place where I grew up, local populations of burrowing owls were endangered, largely because of predation from cats. They are invasive species, it's an objective fact! People always act like it's an attack on their cats to talk about this, like no, I care about my cats AND about the environment, you're just defensive bc you don't like getting called out. If you're really worried about your cat not being happy indoors, just leash train them or get a catio or something! Avoids your cat potentially dying outdoors too! But no, this type of person is too lazy to ever actually be responsible, with the life of their pet or with the environment 🙄

colonizers often transported as much of the wildlife of their country of origin as possible to literally physically replace the ecosystems they were colonizing (make it easier for them to move in, make it harder for the natives to survive).

A couple notes: 1. "Darkling Beetles" are a massive family that is widespread across the world. The Genus Mimopeus is endemic to New Zealand (though not Stephen's Island), although I'm not sure that there is anything particularly unusual about them. 2. Three toes forward and 1 toe back is not a good way to distinguish passerines from other birds, as it is not at all a unique feature. Most non-passerine birds also have feet like this, including shorebirds, herons, hawks, and many more. 3. Passerines are referred to as "perching birds" later in the video, which is another common name used for the Order. But it's not a very good name because many non-passerine birds perch, including kingfishers, hummingbirds, hawks, and many others. (To clarify, Lyall's Wren did NOT diverge from other passerines earlier than hawks did.)

It's not arbitrary not including domestic and feral cats. Politically it might not have been able to get enough public acceptance. It's an example of speciesism towards a non-human animal in detriment of other non-human animals. Because if you want to get rid of feral cats, you need to get rid of domestic ones too, since they're the reason sometimes cats are brought up in the wild.

Anti-speciesist conservation is a very big ask to make, but has been a guideline for hands-off rewilding efforts, so not completely a insensible idea. Just to be clear on my definition, even if the species we prefer over another is not H. sapiens, it's still putting the individual and species welfare above that of individuals of another species. And in response to the original commenter, protecting invasive feral cats over threatened native wildlife in an ecosystem is usually the opposite of what conservation efforts are about, but it still shows a speciesist bias.

[@SugeryGold]

@@NewAge374Yeah thats why it’s important to use our brains and not just let labels like that make our decisions for us. By your definition both removing and leaving the cats, pythons or whatever invasive animal is causing the problem, is speciesism since either way you are “picking favorites”. While humans argue about personal interpretation, wildlife dies because of our decisions that we were too small minded to think about the consequences of. I dont really know what point you’re trying to make because nature doesn’t recognize politically correct terms like “speciesism” and by your logic if you’ve ever chosen one animal over another you are a perpetrator of speciesism so if you ate eggs from a chicken instead of a quail you’re being speciesist.

[@NewAge374]

@@SugeryGold Recognising that you have a bias towards saving one animal over another in a policy without sufficient argumentation, that's critical thinking. Carrying it out anyway because you find adequate arguments that putting more effort into saving one species, would benefit the wider ecosystem -even at the cost of some individuals- is acting thoughtfully and trying to come small-mindedness. Indeed humans are the only species capable of speciesist bias because of the role we've appointed to ourselves as stewards of the Earth. And we must be careful to not fall into the trap of fixing things out of guilt, nor out of infatuation, but go instead for the most rational solution with the highest change of success and stability, ¨sustainability¨ and ecological awareness. I'm only asking we recognise this bias in our decision-making, just like other logical fallacies or otherwise making the experience of a certain demographic the default for all other people (like white, male, straight, wealthy, non-disabled etc)

I grew up on a bird sanctuary island in NZ we used to have kiwi's nesting under our house and penguins under our woodshed. These day's im a possum hunter , sometimes i catch cats , rats , and stotes in my traps ,the predator free plan is not do able really, and wiping out possums is going to hurt a few people and take away a part of our modern culture. The key is conservation efforts like trapping,you can see the difference in the blocks of native I've been trapping for last few years. Theres allot more seedlings coming up and im sure you can hear more bird life. Compared to the blocks im getting into for first time theres a noticable different. The key like with dear and pigs is keeping the numbers controled so they don't become like locusts. I love our native trees and birds but we have to be realistic . And getting rid of possums takes something away from our culture and from poor farming families and kids . Rats are a huge problem maybe offering rat baits to farmers and people who want to control them on a large scale in some sort of deal with doc . We have a problem with wild peacocks up here where i live , it's harder than you think to find their roosting trees and go after them at night, and i don't have money to buy a trap for them. But if doc could supply me with a couple traps for them , id pay for bait and be willing to put time into trapping them along with possums and it wouldn't take me long to put a dent in the population. I tried building bird boxes and hanging them in trees but i don't think im making the holes right size for our native birds but im trying and I grow native trees i plant out around the place . I love listening to the tui outside the house during the day and morepork at night, I've never seen a live morepork but im really hoping to get them breeding by our place by taking out the possums. I need to take out a few magpies as well make it better for the tui . I got cats and they are free to come inside and out as they please mostly they stick around house and farm sheeds I've never had them bring me a native bird but they have a couple sparrows but its mostly rats and mice . I did try using collars with bells on but it became dangerous to my cats with all the fences and things around here ...... anyway rant over ,just its not realistic the plan as is and theres better things you could do that wouldn't cost the tax payers as much and would give a better result. And stop blaming farmers for the environment they are actually great conservationists and deeply care about the land and its native Flora and fauna

How my sister's made extra money for university and how I make a little extra money on top of my disability benefit. I do a small trap line for exercise and because I care about our native birds and bush . These days we pluck the fur and it gets mixed with wool and made into socks, hats, and other cold weather clothing. Possum fur is like polar bear fur it doesn't freeze and it's as fine as silk . If you live in a cold climate it's well worth investing in some of the products. It's also part of our culture possums being in our cartoons and ads and allot of kids grew up going spotlighting for them at night.

I'm a bit skeptical with "saving energy" when it comes to evolution especially when a bird loses its ability to fly, I believe it's more along the lines that it *doesn't* need to fly so it becomes redundant? Like those little fish that live in a cavern so they lost their eyes, what's the point of having eyes if you're living in complete darkness.

[@universe1879]

Its both, growing big wings to fly can cost energy and growing smaller ones cost less, when the bird is in a place where it doesn’t need to fly those big wings costs a lot of energy to do nothing and because of that birds that happen to have smaller wings use less energy to grow and survive, and they have an advantage to survive and breed more small wing birbs as a result

[@Kickilia]

It is a lot about saving energy, because even if you don't actively use something, pure maintainance is energy costly. Growing something it doesn't use (wings in this case) that it then has to spend lots of cells (that cost energy) continously renewing so the wings don't die and rot and become a massive source of problems for the bird -- it's just wasteful when it could spend that energy looking for mates or food. Instead, here, evolution favored birds that had smaller and smaller wings until they disappear and no extra energy has to be spent, since they don't use them anyway.

[@Ezullof]

If flight was just redundant, it would likely still remains possible because it wouldn't be detrimental. Traits disappear not because they are redundant, but because they are detrimental. Energy cost is a relatively common example, and it's likely the case here. The fish in caverns don't really lose their eyes, they lose the ability to see, both because it would cost too much energy to maintain and because mutations start piling on without being detrimental.

And also while we are at it. Keep your dogs in your yard, not barking 24/7, crapping everywhere in the street, attacking neighbours, getting into dog fights, killing wildlife. Just because the poor cat always gets blamed for everything bad. By the way, wild dogs are a major pain, almost worse than the neighbourhood dogs

So, as an interesting side note, we moved to New Zealand last year, and none of the houses have screens. They also don’t have central heating/air like in the US, so the only way to get any air circulation or cool many of the rooms in the warmer months is by opening and closing (unscreened) windows and doors. And so cats (sometimes ones that aren’t even yours 😂) just come and go as they please, and having indoor-only pets is not a realistic option the way it was in the US 😢

[@Chameleonradio]

That's so weird, can't you get screens installed.

[@martywhalen3673]

@@Chameleonradio not as a ready-made thing, it would have to be a custom creation by you or a tradie with sourcing a fine mesh and sorting how to attach it to windows that are simply not designed to hold a screen with opening outwards from the bottom. We are renting at the moment and are even more limited on the types of house modifications we can make, but there's been talk on facebook groups of people trying to do this. I think the short answer is, it is a significant challenge and hard to do (and the only people who seem to care about having screens in the first place are Americans, not kiwis or UK transplants).

Who knew. Cats hunt birds. It was never going to go well.

[@williamdistefano5698]

Cats have been the end of flightless birds since smilodon and terror birds. 🤷‍♂️

[@ChiChiLand299]

If we really did care about preserving the environment and we should probably just ban the ownership of cats and dogs because we can never guarantee that everybody will do the right thing. There are tons of animals let the cats and the dogs will kill in their lives before they die. But we know that's never going to happen and I know even you guys wouldn't be for getting rid of all the cats and dogs in the world even though it's actually for an environmental impact kind of situation is the right thing to do

[@isen2619]

The only reason bird species are struggling in many places to this point is the impact of humans on the environment. We pave over parks and put up glass skyscrapers and spray pesticides everyone and people think cats are the problem! Have you ever been in a natural location to watch a fireworks display?

[@ChiChiLand299]

@@isen2619 yeah and we also brought cats which is literally one of the most invasive species in the world lol And as much as people want to pretend humans are an invasive species were not a species that naturally proliferates and moves into new environments is simply a successful one that's really invasive species who's won the kids transplanted somewhere else that would be impossible under its own means

[@isen2619]

@@ChiChiLand299 Most of the world has many similar predators to cats. Places like New Zealand do not have those similar predators which is why cats are so devastating to the birdlife there. Birds and wildlife in the Americans, Africa and Eurasia evolved alongside cats and cat-like species.

fortunately, feral cats have plenty of predators of their own 😂

[@emmahardesty4330]

Predators shouldn't be introduced to small islands. Bear in mind that most cats don't catch birds--things with superior eyesight and wings. Cats famously prefer things that scurry along the ground. Bear in mind that most birds are packed with disease, probably the one animal most responsible for human deaths. With time, natural selection offshoots human ignorance, and cats on islands such as Japan, England, Cypress, Crete have large, free-roaming cat populations and healthy populations of birds. Finally: How many billions of any bird species do we need?

[@ryangriffin5362]

With the exception of Cyprus all the places you listed have native species of wildcats in the genus Felis, so all the birds in those places are well-adapted to avoid the hunting strategies of domestic cats. In New Zealand there weren't even terrestrial mammals. Those birds had zero chance of adapting fast enough, and many simply couldn't due to their ecological niches. Domestic cats have been on cyprus for millenia, so it's actually unclear what their effect was on local bird populations/ diversity. Shifting baselines make us forget how much harm has been caused. Also not for nothing, but it is well-documented that wildcats in the genus Felis regularly hunt ground-dwelling birds. The many flightless birds of New Zealand that had virtually no predators at all were easy targets.

Not gonna lie, Hank. As someone who didn’t see Season 0 when it first aired, the interruptions to correct yourself and expand on topics are a bit annoying. Though, I understand why this approach would be better than redoing these from scratch. Still, it’s informative.
