It was initially aged as an adult and when I eventually caught up with it on 3rd June, my initial views questioned the ageing of this particular individual. On a constantly moving bird like this, in strong sunlight and the fact it was never really close, it's easy to see how a mistake could be made with the ageing of this bird. Thankfully, camera at hand, the still images allowed for the bird to be correctly aged as a 2nd-summer.
To compare, below are a few images of the stunning adult that was on Lodmoor in July 2013.
|Note the primary pattern, only P10 is old. Note also the lack of a bar on the outer secondaries.|
|Note the neat and tidy rear edge to the black of the underwing.|
