I’ve thoroughly enjoyed watching the great diversity of birds while I’ve lived here in Birch Bay. I’m starting to recognize Mergansers, Harlequins, Canvasbacks; and Mallards are always prevalent, Bald Eagles and Heron, and on and on. I’ve wondered why there isn’t more of a presence of vacationing birdwatchers to this area. Maybe there is and I’m just not in the know.
I am in the know that the annual Wings Over Water is tomorrow, next door in Blaine, WA. It has really expanded since it began eight years ago. It’s quite the family event and holds something of interest for all ages of birdwatchers!
Check it out for yourself!
8th Annual Wings Over Water NW Birding Festival
Saturday, April 17th, 2010
638 Peace Portal Dr., I-5 Exit 276 Blaine, WA
Greet fellow outdoor enthusiasts and view thousands of geese, sea ducks, and raptors that crowd the estuarine habitats ranging from the Canadian border at Blaine to the beaches of Birch Bay State Park. Exhibits of wildlife art, carvings, seminars, and field trips will highlight the one-day festival. For complete details on this festival, visit the following link:
This festival started eight years ago as a forum to highlight the Brant (Branta bernicla nigricans), a small sea goose that is about the size of the common Mallard and stages one of the most spectacular migrations of all waterfowl. The Brant leave their Arctic staging grounds in late fall, they fly non-stop for almost 50 hours to their wintering grounds in Baja, Mexico. Brant perform some of their most important staging in the greater Puget Sound area prior to moving north in the spring. The largest concentrations of Brant in the Puget Sound usually occur between February and May. Peak numbers occur in mid-April, coincidental to the annual spawning season of the Pacific herring.
Brant numbers have been declining in recent decades. This is due in part to the rapid growth of the human population in coastal communities in the Strait of Georgia. This growth causes disturbances to the Brant estuaries, beaches, bays and spits where they feed and rest before their migration north to Arctic breeding grounds.
It used to be a strictly coastal bird in winter, seldom leaving tidal estuaries, where it feeds on eel-grass (Zostera marina) and the seaweed, sea lettuce (Ulva). In recent decades, it has started using agricultural land a short distance inland, feeding extensively on grass and winter-sown cereals. This may be behaviour learnt by following other species of geese. Food resource pressure may also be important in forcing this change, as the world population has risen over tenfold to 400,000-500,000 by the mid 1980s, possibly reaching the carrying capacity of the estuaries.In the breeding season, it uses low-lying wet coastal tundra for both breeding and feeding. The nest is bowl-shaped, lined with grass and down, in an elevated location, often in a small pond.
I thought it was interesting that this goose possesses a highly developed salt gland that allows them to drink salt water. Since they’re considered a salt-water goose, I suppose having the gland is a no-brainer. I wonder how that capability can be adapted to make salt-water drinkable by humans? OK, so I got off on a tangent.
