Zebra Finches Love Pink

27 Feb 2026

Transcription

Chapter 1: What is the main topic discussed in this episode?

2.039 - 19.268 David Cooper

Smart, sharp, and slightly unhinged. Late night's fresh perspective. The Last Show with David Cooper. Our top story tonight, answering the question on the top of everybody's mind. Do birds prefer pink nests?

0

Chapter 2: What is the zebra finch's preference for nest color?

19.408 - 36.872 David Cooper

Because new research suggests some zebra finches would rather defy their flock than compromise on decor. And honestly, same. I'm here with someone who's done research in this area. She's an animal cognition researcher at the University of Alberta. Her name is Julia Self. Julia, what a joy it is to have you here.

37.753 - 39.015 Julia Self

Thank you. It's great to be here.

39.113 - 48.246 David Cooper

I love that you chose as your research area, the color, the preferred color of a certain type of bird's nest. What got you interested in this as a research area?

0

48.985 - 70.673 Julia Self

Yeah. So I got into this in my undergrad and I just love animals. And I think birds and the way that they build is just so cool to have this architect in a different species. And I was also interested in how birds make decisions. And so we used color as a stimuli, but it's just really exciting to see how they build and who doesn't want to know what an animal's favorite color is.

0

70.805 - 80.764 David Cooper

Right? Mine's sparkle. Is that even a color? I don't know. How do you even discover whether a bird wants a certain color of nest? Like, how do you set up an experiment like that?

81.352 - 102.258 Julia Self

Yeah, so we give them different choices of material, and we found that some birds just very strongly preferred one over the other. Like, they would spend hours and hours playing and interacting with and building with pink, for instance, and they wouldn't even, you know, glance at the green string. And so it was cool because we saw that some birds had these very strong preferences.

102.779 - 112.18 Julia Self

And anytime you see this variation in what animals do, it's exciting because you're wondering why. they have this variation. And so, yeah, giving them these options allowed us to see their favorite colors.

112.721 - 120.927 David Cooper

What does it actually mean to say that this bird, the zebra finch, has a color preference? Like, how do you know it's not just random or just that string was closer to me?

121.582 - 134.166 Julia Self

That's a great question. So we know this because we can change a bunch of other variables like where in the cage the string is and have these birds build multiple nests and they'll just keep choosing the same color. It doesn't matter where it is.

Chapter 3: How did Julia Self become interested in animal cognition?

170.911 - 188.612 Julia Self

Whereas others are just, they will not even, you know, look at the other color, touch the other color. And so it really depends. The birds who have really strong preferences will just ignore, you know, what their friends are doing. They don't care what anybody else does. They're sticking with what they like. Whereas these other birds are,

188.592 - 202.568 Julia Self

where they kind of don't care you know maybe they like pink a little they like green a little they use a little bit of both we see that they will change their mind and that they will you know copy their friends and and stick to the the flock basically um if they don't care so much

0

202.7 - 217.993 David Cooper

Honestly, kind of relatable. Like when I was a kid, if my parents bought me a new Lego set, you know, once every quarter or whenever they did, my friends wanted to hang out. I'm like, no, thank you. I'm going to stay in the basement and play with these small blocks. Is that what these birds are doing? They're just like, don't care about what's going on.

0

218.033 - 222.463 David Cooper

And why would they not care what's going on with their peers? Why would they love this color so much?

0

222.865 - 240.638 Julia Self

Yeah, so I had the same questions when I first saw these results, seeing how, you know, they could have a flock of birds doing something else and they're like, you know, forget them. I love pink. But then when I thought about humans and how we behave, kind of like how you mentioned with the Lego, it made sense to me. I mean, I think we all know someone where you're like...

240.618 - 257.4 Julia Self

Doesn't matter what I tell them. This person is never changing their mind. You know, might be politics or religion or something that really matters to this person. Or even, you know, concepts we have within ourselves. I know I have strong opinions about some things. And so in humans, we see that if we have these strong opinions, it doesn't really matter what other people say.

257.42 - 269.055 Julia Self

And so I think it's kind of the same with birds, right? They have a really strong opinion. It doesn't really matter what others are doing. You know, in my own life, if I don't care so much, if I, you know, don't care, it's a coin toss in terms of what I like.

Chapter 4: How do researchers determine a bird's color preference?

269.035 - 278.826 Julia Self

I'm probably more likely to copy what other people are doing than if I'm really convicted, in my opinion. And so when I think about it in terms of humans, it makes a lot more sense than when we just think about it in terms of birds.

0

279.146 - 291.82 David Cooper

And it just goes to show scientifically birds are people too, said no scientist ever. Okay, for the birds that have these strong preferences, do the males do certain things with the nest building pink stuff than the females do?

0

292.34 - 312.628 Julia Self

Yes, this is really exciting. So in zebra finches, the males select and deposit the majority of the nest material. And for a long time, we've referred to the male bird as the primary builder. And we thought that he did almost everything. But there's new research coming from our lab led by Dr. Ben Whitaker that shows that actually the females are doing a lot more than we thought.

0

312.708 - 323.684 Julia Self

And so in my experiment, we examined the male behavior because of previous research. But I'm excited to see the females' role in nest building. being more examined here in the future.

0

324.225 - 338.226 David Cooper

I mean, this mirrors the last 10,000 years of human history too. And honestly, I'm not surprised. Are the females doing different stuff with the nest materials than the males? And can a female override the male's preferences?

338.932 - 359.905 Julia Self

So sometimes. So in my experiment, there was one pair of birds, a male and a female, where the female just deposited all the string. And that was really unusual. And I told my colleague and, you know, combined with their own observations, they decided to examine this question because for a long time we thought, you know, the male selects and deposits, the female might rearrange.

360.406 - 378.849 Julia Self

And now we're seeing the females doing a lot more. Some of them deposit, some of them don't deposit at all, some a lot. And so We see a lot of variation among these pairs and in terms of what the male and the female are doing, which is exciting. And I think also kind of reflects like the variation we also see across species in our own lives in terms of what individuals do.

378.909 - 379.971 Julia Self

And it's exciting to see.

379.991 - 395.247 David Cooper

I have to ask at least one serious question from like a conservation perspective. Does understanding how animals use or ignore nest materials, how they engage with each other socially, these birds, does this help us with any conservation efforts?

Chapter 5: What does it mean for zebra finches to have strong color preferences?

480.074 - 497.074 Julia Self

Yeah, it's super interesting to see how different individuals prioritize their own opinions versus opinions of others. You know, maybe these birds who are weakly biased, maybe they're just people pleaser birds and they're just relying on, you know, or bird pleaser birds, I guess would be the term here, but just relying on others to make decisions.

0

497.374 - 508.427 Julia Self

And so it's really interesting to see how different individuals balance their own preferences against what others are doing. And it's exciting to see, you know, in the future, future research, what we might examine with that.

508.778 - 510.883 David Cooper

Julia, if you could build a nest, what color would it be?

0

510.943 - 512.326 Julia Self

It's got to be blue.

0

513.508 - 514.45 David Cooper

Maybe orange for me.

514.931 - 515.493 Julia Self

Orange, yeah.

515.773 - 522.387 David Cooper
