Put a timer on for 10 minutes and then place a tick next to each bird you see. Can you do this three times in the same day? We suggest first thing in the morning, around lunchtime and then in the afternoon when school might usually end.
If you would like to extend this task, you could draw a bar chart to show the most common birds in your garden. We did this activity for 3 different days in the week, and then compared our bar charts.
