Identifying Helicopter Seeds
In this tutorial, we will learn about how to identify helicopter seeds.
Here in Ireland and the British Isles, you are most likely to find the following helicopter seeds:
- Field maple
- Norway maple
- Sycamore
How to identify our helicopter seeds
Field maple seeds
Field maple seeds have the greatest angle of the three and grow almost horizontally away from each other. Each seed is curved in an upward scoop from the bottom.
Norway maple seeds
Norway maple seeds also grow far apart from each other, but at a closer angle than field maple seeds. Each seed is broad at the tip and has a wavy appearance to its edges.
Sycamore seeds
Compared to field maple and Norway maple, sycamore seeds are smaller and they grow much closer together. Each seed is rounded at the tip and curves outwards at the bottom.
What are helicopter seeds?
Have you ever asked yourself, what are helicopter seeds and why do they have wings?
Well, there are two types of flying seed – parachute seeds and winged seeds. Helicopter seeds are winged seeds. Their wings are single, stiff, flat membranes, which are attached to the actual ‘seed’ bit and designed to help the seed catch the wind as it falls from the tree and fly away. Theis helps it move away from its parent tree so it is not competing for food, water and sunlight.
The reason they are called helicopters is because of the way they spin as they fall from the tree. But, they have other names too, including spinning jennies, whirligigs and whirlibirds. But their proper name is a samara.
Have you ever wondered why maple seeds spin as they fall ? You can find out here.
Summary
Well, I hope you have enjoyed learning all about helicopter seeds? Do you remember their names? They are:
- Field maple
- Norway maple
- Sycamore
Helicopter Seed Nature Study
Now it is time for your helicopter seed nature study. Are you ready?
Your first task, is to download the resource that accompanies this lesson.
Your second task, is to go out on a nature walk and try and find all three of the seeds we have just learnt about. I want you to:
- Examine the shape of their wings
- Look at the angle between the two wings in a joined up pair
- Feel the texture of the wing around its different sides
- Notice the size, shape and location of the ‘seed’ relative to the wing
