Saw the attached gannets flying past Portland Bill in 2013, but recently noticed the bird bottom left which is smaller.
Both the original photo attached, and also a zoomed/cropped pic of the individual bird so you can gauge size from the gannets.
I'm presuming an immature Gull, but the neck looked short in comparison to where the wings start and the length of body/tail beyond the wings (but that might just be the angle as the bird changed direction?
Thanks in advance for any ideas
