What are nasal cones?

If you take a close look at a peregrine falcon, you'll notice a small structure in their nares. All birds in the family Falconidae have this feature. That includes falcons and caracaras around the world. This bony tubercle has an important function, and is known as a nasal cone.

When you started to explain what the nasal cone does the first thing that popped into my mind was the SR-71 engines. They had a cone that looked very similar and actually moved fore/aft to control the pressure. Then towards the end you showed airplane engines. Made me chuckle.

I have a pair of Peregrine falcons breeding on an urban bridge about a kilometre away and regularly see them in flight. I've also seen American Kestrels hunting over train tracks near my house.

[@petralawson2044]

Love your videos! You're very good at explaining things 0u0

[@donnaleighjenkins4952]

Very interesting explanation! Beautiful bird!

[@kitkat5765]

So cool! I saw peregrines mating last weekend, and I love them. (We also have a few kestrels, though they're harder to find for some reason.) I think Falconidae are my favorite bird of prey family, but I don't know much about caracaras--will have to research them! 🤗

I saw a peregrine falcon just yesterday and I have seen caracaras.

The shock cone in a jet engine is similar in function but slows down the air so the flames of combustion dont get blown out by supersonic airflow. Interesting none the less thanks

Peregrine falcons have been known to fly and stoop ( dive ) at a speed of 399kph. The Latin name of the peregrine falcon is Falco peregrinus.

[@1stcrg]

The only falcon around in my area and country ( New Zealand ) is the New Zealand falcon. ( Falco novisselandee ) all this information is not from Wikipedia or an encyclopaedia. The Māori name for the New Zealand falcon is kārearea. I’m not a Māori person. I’m halve English and halve kiwi.

I think this presentation is confused, and attempts to pass along that confusion. They did a poor job of explaining Bernoulli’s theory. Faster moving air creates less pressure SIDEWAYS only. Head on, it creates more pressure. After the theory is explained properly, the next step should be to explain the aerodynamics of the bird’s beak in various regimes of flight. Then demonstrate how the fast moving air passes the beak. Birdie, please go back and redo this presentation? It is an interesting subject when properly explained. Courtesy of Half Vast Flying

[@allthingsbirdie]

Thank you for sharing that knowledge! It's clear that you have a deep understanding of these concepts. My intent is to convey Bernoulli's principle in more rudimentary terms for non-engineers. Yes, there is much more to it! It's often a delicate balance of explaining technical concepts, while at the same time, not going too far afield.

@@allthingsbirdie You do a great job! 👍

[@allthingsbirdie]

@@OspreyFlyer Thank you, I appreciate that!

The presentation is perfectly adequate for entry-level exposure to the subject for people who do not hold degrees in Aerospace engineering or mechanical engineering. If you are so interested in the subject and can explain it better, why not do it yourself? :)
