I only dared to name the herring gull as it was identified as such by observation.org (waarneming.nl) , I would totally have no clue myself
Like I mentioned in another thread/ post my relation with my R7 for some reason did not work out for my sports shooting, an area where that camera is also aimed at according to some of the marketing. Off course I got some great rugby shots with the R7 as well, but I felt much more confident when using my R5 or R6 and my potential keeper rate was a lot higher, at least it felt that way but I never did the exact math.
