[SBB] Continuing Pectoral Sandpipers

This morning Frank Vanslager and I had a PECTORAL SANDPIPER in New Chicago Marsh on the southern side of the Environmental Education Center entrance Rd. Later as we left Pete LaTorrette pointed out a second PESA on the northern side of the entrance. Pete felt that the second bird was a male (and intuitively that the first was a female). While near the first island in Salt Pond A16 Frank and I saw one of the juvenile BLACK SKIMMER fly around the island and even attempt to skim the surface on the far (smooth water) side of the island. Both BLSK parents were also on the island and a second young BLSK was seen walking along the island some distance from where the first had landed.(Frank briefly saw what he thought may have been a third Juvenile where the first had settled in after its flight around the island). They probably won't be around much longer. Some HERRING GULLS were on the island but still no sign of Thayer's Gulls. We then had a couple BURROWING OWLS and LONG-BILLED CURLEWS in Arzino Ranch but nothing "notable" at Sunnyvale Baylands park.
