When trying to photograph birds as they take off into flight
watching and understanding their body language is very important.
Birds who are ready to fly become more alert and take on postures
that are sometimes obvious and sometimes more subtle. Learning them
enables you to be prepared when the moment of lift off occurs. This
is a juvenile Cuckoo seen at Parkgate, Cheshire in September 2008.
A bird quite reluctant to fly but when it was I was ready.
