World WHAT Day?

Malibu Lagoon

I’m sure you’ve all sent out your ‘Happy World Wetlands Day’ cards and booked your dinner reservations to celebrate… No? Only me? Well, today is in fact World Wetlands Day and the United States is signatory to the Ramsar Convention (named for the city in which the global wetlands conservation agreement was signed).

If you live in Los Angeles, you might have noticed we don’t have a lot of wetlands anymore; California has destroyed 90% of its to development, but locally on Santa Monica Bay we do have the Ballona Wetlands and the smaller Malibu lagoon. These sites are of vital importance to migrating shorebirds. Bird migration, the seasonal movement of birds from their breeding grounds to their wintering grounds, is one of the most spectacular, physically demanding, and mysterious wildlife events. Wetlands are one of the only places these birds can stop and refuel on their epic journeys.
For the second year, Santa Monica Bay Audubon has participated in the Point Blue Pacific Flyway Shorebird Survey and Migratory Shorebird Project at Malibu Lagoon to track and monitor birds stopping at our local wetlands. Check out these links:

Here are some record-setters that make migrations and wetland stops so amazing according to a National Audubon list:

■ THE LARGEST CONGREGATION O SHOREBIRDS Over one million shorebirds, mostly Western Sandpipers and Dunlins have been recorded in a single spring day on Alaska’s Copper River Delta. In fact, practically the entire North American population of Western Sandpipers stops thereto rest and refuel on a diet that consists almost entirely of tiny clams.

■ THE LONGEST NONSTOP FLYER Bar-tailed Godwits make the longest nonstop migration of any shorebird species traveling 6500 miles from Alaska to New Zealand, one way, without stopping.

■ THE FARTHEST TRAVELER Pectoral Sandpipers make the longest migratory flights of all birds They winter in southern South America but breed as far North as Central Siberia.

■ THE FASTEST FLYERS When migrating with good tail winds, shorebirds can fly up to 60 miles per hour.

■ TIMED TO DINE Eighty-percent of Red Knots in the Western Hemisphere time their arrival at the Delaware Bay, from the southern tip of Argentina, just in time to dine on millions of horseshoe crab eggs. The eggs have been stirred up to the beach surface by tides and the masses of egg-laying horseshoe crabs.

■ RAVENOUS EATERS In order to gain enough weight to continue their migration to the Arctic, Sanderlings eat one horseshoe crab egg every 5 seconds for 14 hours each day until they have rested and fed enough to continue migrating.

    Fascinating information! Where is the dinner? Indeed, there should be one to talk about all things migratory. EDNA
