Politicians may not belong in the bedrooms of the nation, but that's
no reason Canadian birders shouldn't sneak an inside peak at the mating
behaviour of the Sharp-tailed Grouse. This May 13 to 15, at the Delta Marsh
Birding Festival, a tour of one of the male grouses' dancing grounds
earn visitors a bird's-eye view of the ancient courtship ritual known
as a "lek." It's just one of many activities organizers have
planned for the seventh annual birding festival at Manitoba's Delta Marsh,
one of the largest freshwater marshes in the world.
Spanning some 22,000 hectares at the southern tip of Lake Manitoba, the marsh
began its life roughly 2,500 years ago, when the lake's currents deposited
sand along its southern basin. Today, as a result of dune-ridge succession,
a 50-kilometre band of deciduous trees and shrubs has emerged between the beach
and marsh, creating a natural migratory pathway. Clouds of mosquitoes and other
insects in combination with the physical habitat create a marsh that's
hard to resist for nesting songbirds. Indeed, the Delta Marsh Bird Observatory
(DMBO), which performs daily operations of banding and census-taking during
spring and fall migrations, estimates an average of 7,500 visiting songbirds
a year, with the yellow warbler topping out at an average 1,500 per year.
The marsh's unique characteristics inspired outdoorsman James Ford Bell
(founder of General Mills) to consult with Aldo Leopold in the early 1930s
about his ambition to create what is now known as the Delta Waterfowl and Wetlands
Research Station. In operation since 1938, Delta is famous for its ornithological
research; in 1999, the marsh was designated an Important Bird Area by Birds
Studies Canada and the Canadian Nature Federation. Boasting some of the highest
breeding densities of yellow warblers and Baltimore orioles in North America,
the marsh has a checklist of 307 species with spring proving to be an especially
rewarding time.
Early registrants and volunteers to the festival might snag on-site accommodation
at Mallard Lodge, the 932-hectare estate built in 1932 by Winnipeg businessman
Donald Bain. From there, they can take daily guided birding tours, hike along
interpretive trails, sit in on workshops (including one on "First Aid
for Birds") and attend a banquet and a fish fry, where guest speakers
share their insights into the world of birds.
