@@thebrainscoop well yes, as long as they persisted that was the case. Elephant birds could have probably fed more people though; if having been handled with sustainability in mind.
@@murockey They probably took a long time to reach maturity making them very inefficient as a food source. For maximum pounds of animal per unit time, you want small, not large. Insect farming is far more efficient than chicken farming which is far more efficient than cattle farming.
Awyiss thanks for also covering their colors! I'm always interested in knowing why things look the way they look. I've read a study (can't find it again now) that egg colors are mostly just variants of blue and brown-lighter means less pigmentation and darker means more. I'm always impressed to see all these different eggs that the birds somehow came up with, despite the limitation.
So interesting, as always. The images of the collections and discussion of their value is always so enjoyable. I was particularly struck by the comments on the high frequency of blues in eggs, especially due to blue being such a challenging color to make in nature.
With respect to brood parasites, I've heard some facts that I don't know if they're true or not. Such that sometimes the "victims" notice the extra eggs and will kick them out of the nest. But if too many local birds do that, the parasitic parents will go around and destroy nests. Turning it all into a weird extortion racket. Nature is almost always even more complicated than it at first appears.
Yeah, that behavior was published in a 2007 paper by J.P. Hoover and S.K. Robinson: "Retaliatory mafia behavior by a parasitic cowbird favors host acceptance of parasitic eggs" www.pnas.org/content/104/11/4479
U can see on this man how much knowledge he has. I bet he could go for weeks non stop talking about birds and eggs in general. Also, the tables he prepared to talk about... that's not like anything else out there, you would never see a paleontology table rich like that. We should be paying more attention to birds. Also, big props to him, such a care and dedication.
I do field research in linguistics in a remote area of Papua New Guinea. A woman from a neighboring village had found a cassowary egg, and was selling it. I bought it (I think it was 5 or 10 kina). It was a beautiful mottled green color. The mother of my hosting family cooked it up for us, and it easily fed all five of us. A good topping for our sago jelly. Also, I love the videos! Thank you for making them to teach us :)
I found an interesting article about pigment in eggs not only warming up eggs, but also protecting the interior of the egg from UV. Its about blue eggs, but maybe this is also part of the reasom why the emu eggs are dark (if the pigment also absorbs in the UV range). www.sci-news.com/biology/mystery-blue-green-bird-eggs-03908.html
We have groove-billed anis, the smooth-billed ani’s nearest relative, here in south Texas. It’s really something to see a bunch of them tending a communal nest.
Hey for all German-speaking listeners, there is a recently published book called "Die verlorenen Arten" (The lost species) by Christopher Kemp. It's about all the forgotten or false identified specimens in Museen all over the world. It speaks for example about the olinguito that has already been covered on this channel.
Emu eggs are actually a sort of turquoise when they are laid, there is a texture and the top surface of the texture is a different shade than the grooves of the texture. They darken and loose some color within a few days. Perhaps this rapid color change helps the incubators know when it's time to get started. The females lay one egg every few days and when there are enough, the male emu begins incubating the eggs and doesn't leave the nest for food or water until they hatch.
That was very interesting. Emily's casual interview style is always appreciated and John seemed like a guy who would be fascinating to talk to and learn from. All in all, it was a very good episode. Thanks for sharing that with us.
I had no idea grackle eggs were so cool. I have a huge flock of them nesting in my yard this spring with a few nests in the hedge of arborvitae near our driveway. I'm going to go make sure I have a quick peep before they hatch! Makes me wish I had a gopro...
I've often heard that animals can't really make blue pigments, and the blue color that IS found in animals is purely structural. Is the blue color in eggs structural? If it's from byproducts of pigment production, that would suggest that animals CAN make blue pigments. If it's structural color, that would suggest that it is not a byproduct but a specific adaptation to something...
5:00 a cool experiment I learned of in neuroscience showed that birds have a sense of 'eggness' and certain shapes and sizes are preferred over others. They tried artificial eggs of different shapes and sizes and recorded which eggs were preferred:) Kind of like are sense of adorableness and how certain specific details are adorable and others are not. Now...it doesn't explain why the birds might enjoy an 'upgrade' (though sometimes they reject new eggs) but it's pretty cool.
Sometimes I watch videos like this just to get a glimpse of the passion that people have for learning about the world. It's always enlightening and makes me want to follow suit.
Just got the book of eggs a week ago! It's a wonderful piece of scientific literature to look up all the amazing bird eggs. Tanks for this very informative and educating video!
Wow, what a great video! So many ecology/life history/conservation concepts all connect to egg traits. I wish I had shown this to my ornithology students!
DDT was often used as a pesticide specifically for dengue mosquitoes and it was actually able to eradicate the pathogen from some countries like it was insanely effective, so its interesting to hear about it from another perspective where it was affecting the falcons ability to hatch eggs
For about five years I had a cowbird that came to me every summer, she would even come in my house. The are definitely one of my favorites too. They are the mafia of the bird world, but an excellent friend to me. Although when the males would show up to court her I was less pleased... man they were loud. I named her Lisa. No idea why.

Brilliant video! I love that there is still so many questions about bird eggs that are unanswered and hearing how people figured out DDT was the cause of the falcon egg issue was inspiring :) Thanks for making such an interesting video.
I read an article recently ( vis.sciencemag.org/eggs/ is not that article, but it seems to be a pretty fancy breakdown of the conclusions ) that described a process of surveying and categorizing a wide sampling of bird eggs and comparing them with the parent birds for a variety of factors to see if anything correlated with egg shape so as to actually explain why egg shape is so varied in birds. It seems like the main thing that effects a given species' egg shape is the shape of the species' body- their aerodynamicness, basically. That's really cool! Even in 2019 we're still learning new things about the ancient egg.
Loving the curious content from the channel. It would be fascinating to do some research in dinosaur egg colour if I ever got a PhD position in the future. Since birds are descendants of dinosaurs, it would be quite a sight if we step back into the mesozoic where there are (hypothetically) flamboyant eggs everywhere during the nesting seasons.
Theory on the emu eggs. They're dark so the female isn't around the nest as much. If she were to be constantly incubating then leaving would make it easy for predators to find the nest. Keeping the eggs dark means they can keep warm without the mother. Letting her eat and keep healthy to protect the eggs when needed. Similar to how fawn's blend in with the environment. It keeps them safe while the mother only comes to feed them till they are stronger to stay with her.
So does the egg have to be partially destroyed to get the shell thickness? If so how is an egg chosen to sacrafice or do you guys have already broken egg shells to use?
Thank you for an interesting and educational video! I immediately got intrigued by the subject and bought The Book Of Eggs online. New reading material 🤩

Hi Emily! Does the Field's egg collection only focus on bird eggs? Or do they have reptile eggs as well? Is there a separate collection for reptile eggs?
So, in regard to Kiwis' large eggs: Did they start as an elephant bird, with big eggs, and then evolutionary pressure made a population of them smaller, but did not correspondingly make the eggs smaller, thus resulting in the birds' bodies adapting around their large eggs instead?

In a way it makes sense that there might be fewer in areas where resources might be more limited since blue is normally very costly to make. The most prominent blue egg layer in north America is the American Robin. Also in north America is the brown headed cowbird. Whereas most bird don't seem to notice cowbird eggs, I've seen videos where robins will reject cowbird eggs because they look too different from their blue eggs. So my theory was that the blue possibly evolved as a counter to brood parasites. Or perhaps its just a coincidence. Still, its interesting to note.
I wonder what a roadrunner egg looks like, I used to live around them but never payed close attention to the nests (probably because mamma bird did not like you if you did)
They're emptied. If you look closely you can see little holes drilled into them to drain them. Shells won't rot, you just have to be careful not to crush them.
So like, why, how and at what point do they drain the eggs? Looked like they all had holes drilled in to them, so they only keep the shell of the egg for research? Kinda feel like that'd be an obvious question to include in a video like this. Certainly peeked my curiosity.

Many civilisations & cultures see the egg as the embodiment of the soul.
is there a collection of reptile eggs? Aren't they more leathery and does that make them harder to preserve?
They do have a different consistency. Any reptile eggs we have in the collection are likely stored in alcohol in jars.
Why are flightless birds from Africa and Australia, which by the late cretaceous were already quite geographically separated, so interrelated?
