Looks like it has a black tail tip, eliminating Red-legged. It also does not look to have the contrast expected on secondaries and inner primaries that Red-legged would show.

good call, Peter

I’ve never seen an immature black-legged kittiwake with those underwing patterns.

Hi all -

This could be a first-year Red-legged Kittiwake. Worth looking into in any case. Not many photos on line of underwings of RLKI but here's one that shows a similar pattern:

Both the primary coevrts and the tertial area being marked dark. By contrast I can't find a BLKI with either. February is the month for RLKI in CA.

Thought it worth mentioning in case others want to go look for it.

Hi all,

I had brief looks and managed a single photo of an immature Black-legged Kittiwake seen just offshore from the Cliff House at about 0815 this morning. A bit more detail at my eBird checklist here:
<https://ebird.org/view/checklist/S52301096>https://ebird.org/view/checklist/S52301096

I think the photo supports my ID, but I'm a little puzzled by the apparent dark markings on the underside of the left wing (perhaps the primary coverts?), which I don't see as expected in the field guides I checked... comments welcome.

Good birding!
