Bird survey

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

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.

    How do you know when a bird is singing & when it’s calling? I think I know the answer, but it would be good to hear it from someone who knows!

    Thanks,

    • Hi Hen, Apologies for the delay in responding but I have been in Lapland for three weeks. There are no hard and fast rules to the difference between bird songs and calls. A birds call is usually rather repetitive and the song more varied but not in all cases.

      Songs are more musical and complex then calls. They are usually only produced by the male. With most birds the song is associated with breeding. The male is singing to find a mate and/or claim and protect territory.

      Calls are usually not as musical and varied. Birds use calls to communicate with each other and between members of a flock or family. There are calls for aggression, warning, identification, flocking, hunger and many others.
