Fine photos, as usual Tom. I suspect that snazzy face actually is camouflage, breaking up the pattern of the head visually.

Hello birders, 

Over at the very full Teller Lake No. 5 are a few juvenile Pied-billed Grebes with their striking black and white facial patterns. Most juvenile birds look drab and camouflaged, for good defensive reasons. But Pied-billed Grebe juveniles are an exception, along with Masked and Ruddy Ducks. Any others? Must be an evolutionary reason for this, but whatever the reason, snazzy-looking young Pied-billed Grebes seem to be enjoying their first summer before turning into drab adults.

Here are they are, plus a few others from Sunday: http://bit.ly/Vg8Ifb
