Black-tailed Skimmer

Observation - Black-tailed Skimmer - UK and Ireland. Description: I have pegged this one as an immature male because the abdomen seems a little wider and the antehumeral stripes appear more cleanly yellow but I am not certain of this aspect and any guidance would be appreciated.
