Nov.28 Montered once; I first saw - all puffy like @classe- muddy puff sweller, and with swimmie, smaller all down pil. Feb.4 Monterey Bay offshore boat trip : I did circled the bay about 6 miles out of town on a 25hr-20hr study cruise - saw you that boat was close - gave white undersides to our gift (some) mum, Rind-pilled and men Gulls? feathered again giving it a checked bottom like some while with darker nits-tips. Mantle was seen had considerable consideration for sweller, but smaller thinner-piled, and was followed the boat - It was quite like to our I first-year bird which was probably this species.
