This is the eighth week of our online home learning resources, hopefully you are enjoying them and learning something. This week we are looking at weirs. Do you know what a weir is? At the end of this session you will do! The Wildlife Fact file for this week is about the kingfisher, an unmistakable visitor to our rivers. Keep your eyes peeled for the bright blue and metallic copper colouration of this beautiful bird.
We have introduced these online learning opportunities in response to Covid-19, which has prevented us from going into schools in the Ribble Catchment as we normally would. This is our way of bringing our educational topics to you at home so you can continue to learn all about rivers and wildlife. Each week we will be providing a new main topic, a Wildlife Fact file and a quiz.
Find out all about weirs – what they are, why they were built and why Ribble Rivers Trust removes them!
This week’s Wildlife Fact file is all about the kingfisher, read about it below and click on the image to open it as a pdf.
