odd Neotropic Corm ID; Rose-breast
First, some little bit of bird news. There was a male ROSE-BREASTED GROSBEAK in residential Point Loma on 2 April, near the corner of SilverGate X Charles, but it hasn't been refound. Given the "early" date, this is very likely a bird that wintered somewhere locally, as it is 'too early' for a spring vagrant. On 4 April, there was a good count of 200 Surfbirds at low tide on the beaches in Coronado (Hotel del Coronado area), probably eating Grunion eggs.
Concerning the two Neotropic Cormorants at Lake Cuyamaca, several other folks have brought up the point that the immature bird is abnormally pale for this species. Guy M. says he has never seen one this pale amongst the hundreds he has seen over the years at the Salton Sea. Normally they are darker below than young Double-cresteds, but this bird is very, very pale throughout. Hybrids between the two species are known to occur on a somewhat 'regular' occasion, but the bird is very small–appearing as small as the nearby adult, which looks just fine for a Neotropic, of course. Presumably a hybrid would appear more "intermediate." This bird also seems to be paler than normal in photos in other ways as well, with an odd pale patch on the side of the face, and perhaps even a paler-than-normal back (?). So, perhaps it is just a somewhat oddly pigmented young Neotropic? But, it would be good for folks to obtain better photos of that bird, when not plagued by fog and drizzle as those on Friday were, and concentrate on getting photos showing detail of the facial region (supraloral area, etc.), as well as the upperparts, etc. Given the bird's small size and slim shape with longish tail, it may well be a Neotropic, but it does not appear 'normal' plumage-wise.
