First migritory shore birds of the year

On Wensday April 8 and Thursday April 9 2015 The first  migratory shore birds showed up at Sitka national  historical park. The mane migratory shore bird that showed up was Calidris alpina common name for Calidris  alpina is Dunlin. I saw the Dunlins on Thursday April 9 but I heard that on Wensday April 8 I heard that a big group of shore birds  where down there but they weren’t down their the day before witch would make since because on Wensday  their was a big rain storm that came through so it most likely landed to wait out the storm and feed before they continued their migration north most of the Dunlins that were there were in there winter plumage still there was one in there that had its summer plumage on. There was about 4-6 Dunlins, 50-150 Surfbirds, 10-15 rock sandpipers, and 4-6 black turnstone it was exciting.                             Arenaria melanocephala Black turnstone                               Aphriza virgata  Surfbird                                     Calidris alpina Dunlin                               Calidris ptilocnemis  rock sandpiper
