@David B. If you see these birds in area A, when you count them, one or two of them fly away. However, Two birds have flown to area B which you have counted. And then the people in area B have also see them and register the two birds in their reports. Aren't they four birds? In fact, only two birds should be registered, not four birds.😂Right?

@Percy Just count how many you see and hear. The important thing is the year to year comparison

I'm a little curious about this activity. Birds fly away when they feel frightened. How do you calculate their quantity accurately?😁

It's pretty cool. A science research which conducted by every citizens~ And it's very meaningful, scientists cat review previous data to observe the species and climate change~

@Joyce They are events done around the country this time of year. Teams cover specific areas and count how many of each species of bird they see.
