Shorebird Migration

A noisy Lesser Yellowlegs with three Least Sandpipers
Shorebird migration has started!!  This was emphasized by the number of shorebirds, especially Lesser Yellowlegs (Tringa flavipes),  seen yesterday.  Dr. John Webster tallied over 150 of them at a location in the parish of St. Philip. He commented “Migration in progress …flocks coming down to drink, bathe, rest and then depart again heading South” towards South America.

In the evening  I visited the wetlands at Chancery Lane and saw more shorebirds including five Willets (Tringa semipalmata), and a Whimbrel (Numenius phaeopus).

The day before Carla Daniel of the Barbados Sea Turtle Project saw another Willet at Bath Beach in St. John , which suggested that this species was in the 
midst of migrating.  This influx of shorebirds was not surprising with the weather we had yesterday.  Most of these birds would have passed high over the island or to the east, but in adverse weather conditions, many seek shelter and make landfall, staying just a short while before continuing to South America.  I am expecting this trend to continue into today so be on the lookout. 

Below is a list of shorebird species seen yesterday:

  1. Black-bellied Plover (Pluvialis squatarola) (18)
  2. Semipalmated Plover (Charadrius semipalmatus)
  3. Whimbrel (Numenius phaeopus)
  4. Ruddy Turnstone (Arenaria interpres) 
  5. Stilt Sandpiper (Calidris himantopus)
  6. Least Sandpiper (Calidris minutilla)
  7. Semipalmated Sandpiper (Calidris pusilla)
  8. Short-billed Dowitcher (Limnodromus griseus)
  9. Spotted Sandpiper (Actitis macularius)
  10. Solitary Sandpiper (Tringa solitaria)
  11. Willet (Tringa semipalmata) (5)
  12. Greater Yellowlegs (Tringa melanoleuca)
  13. Lesser Yellowlegs (Tringa flavipes) (152)
