Brilliant Birds Activity

Brilliant Birds Activity Card The Best Of The Nests Local birdwatcher Mrs Twitcher is an expert on birds’ nests. “I think birds are brilliant,” she told our reporter. “I don’t think people can build nests like birds do.” Do you think Mrs Twitcher is right? Your challenge Can you build a birds’ nest? Make sure you only use your pretend beak! How will your nest survive in the wind and the rain? Discuss • What do birds use to build nests? • How do you think they decide which materials to collect? • How difficult do you think building a nest will be?

Getting started What materials can you find that you might be able to use to build your nest? Which ones do you think will be best? Do you need different materials inside and outside the nest? How will you keep everything together? You could start with a small bowl made out of modelling material. What other ways can you think of to build a nest? 2/2 Test your ideas What will happen to your nest on a windy day? What will happen to your nest in rainy weather? What works well and what could be improved? Share your ideas Take pictures of the best nests and make a display for Mrs Twitcher. Give a presentation on building birds’ nests. Extra things to do Do birds with different shaped beaks make different nests? Are there any unusual materials that birds use to make nests? Find out if all birds build nests. Remember to hold you pretend beak in your hands, not your mouth British Science Association Registered Charity No. 212479 and SC039236
