Among the Fulmars was one very smart intermediate phase bird. These dark birds often turn up this time of year, so a good time to look for them. I only normally see them at distance while seawatching, so good to get some nice views and photos up close.
Here's a comparison of a 'normal' light phase (left) with this intermediate phase bird (right) and a couple of flight shots of it below. Also notice the darker band on the bill compared to the normal phase bird.
