A successful gull watching day

I had an enjoyable day today with sightings of a Yellow-legged Gull, a Caspian Gull, a Scandinavian Herring Gull, and Common Gulls with dark head streaking.

As a bonus, the photos turned out great as well.

2nd-calendar year Yellow-legged Gull

Sightings of Yellow-legged Gulls (Larus michahellis) are rare in my local area so I was quite pleased to discover this individual in a large flock of gulls just outside the city center.

3rd-calendar year Caspian Gull

Caspian Gulls (Larus cachinnans) don’t show themselves much where I live either and when they do, it’s usually a first-winter individual. Seeing a 3rd-calendar year in the same flock as the Yellow-legged Gull was therefore a nice surprise.

Note the mirror on P10 on this individual.

Common Gulls with dark head streaking

The same flock of gulls also consisted of some 60 Common Gulls (Larus canus). Some of the adults showed conspicuous dark head streaking. One of them obliged by making a nice fly-by:

Scandinavian Herring Gull

In a different flock of gulls nearby, I spotted this adult Scandinavian Herring Gull (Larus argentatus argentatus).

Note the reduced black on the outer primaries, the Thayeri-pattern on P9, the absence of any black markings on P5 and the relatively dark-pink legs.

Ringed Black-headed Gull

To finish my gull session of the day, a Black-headed Gull (Chroicocephalus ridibundus) ringed locally in December as White EJF0 presented itself nicely:

All in all, a good day’s work!
