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 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 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.
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.
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.
Well, I hope you have enjoyed learning all about helicopter seeds? Do you remember their names? They are:
Now it is time for your helicopter seed nature study. Are you ready?
Your 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:
