It’s a busy time of year for surveying and monitoring species. I was up early the other morning to do a dawn survey of the birds on one of our reserves
Each species of bird in the United Kingdom has its own unique code . In the case of this Song Thrush the code is ST
Standing at a specific location for 15 minutes
I record all the birds I see and hear around me on a sheet of paper using codes
If a species is singing I put a circle around the code, if it is calling I draw a line under the code, if it is flying I draw an arrow to represent its direction of flight
This is repeated at 15 locations on the site, 6 times during the spring.
