BirdWords: Beaver Dams Help Bird Habitat
Article by Jeannette Carroll
Last October found the Sacramento River dropping lower and lower. The slough along Redding’s Cascade Park dropped to ankle-deep water. The ducks were gone. But wait, despite low Keswick Dam releases, residents along the slough noticed the water level begin to rise.
Puzzled, they followed the slough down to Cascade Park and discovered an amazing beaver dam more than 50 feet in length and 3 feet high, constructed of tree limbs and branches, twigs, grass and mud. Its height gradually increased to 4 or 5 feet. The dam survived December’s downpours and, even after our dry January, continues to hold water in a pond that extends over a quarter mile. The pond is well appreciated. Birds, like all creatures, need the right habitat. The Cascade beaver pond is creating a winter home for mallards, wigeons and other dabbling ducks. The dabblers are those who tilt bottoms-up to browse for pondweed, snails and underwater insects.
Along the pool’s edge, an egret patrols in its sharp-eyed hunt for fish, frogs,or just about any animal it can gulp down its long white neck. A steel-blue kingfisher rattles over the pond, taking advantage of the still water to spot its prey. Even a Barrow’s goldeneye, a diving duck typically found in the deeper river, has found a place to rest in the quiet pond.
Of course, any engineering project has costs, too. Without the dam, the slough would now be a riddle of exposed rocks. Shorebirds such as killdeer and yellowlegs, and also jays and sparrows, might pick for food in the trickles through those rocks. As it is, they will be confined to the drier habitat below the dam.
For people, beaver dams can be positive or negative, too. Fortunately, the Cascade pond is only wetting the slough, not posing a threat to area homes.
In the Midwest beavers are being reintroduced in some areas to hold water, a sort of substitute snowpack in the face of dry summers.
Beavers are native in Shasta County and throughout most of North America. Like the dipper, a bird of our mountain streams, they have an extra set of transparent eyelids that enables sight under water.
Beaver families form colonies and may have as many as eight members. Reaching maturity in three or four years, they breed in January or February, and usually have three or four kits. Because they are mainly nocturnal mammals, beavers are not often seen. Residents near Cascade Park have found a second dam on Olney Creek, but checking early and late, have not seen these great engineers at work. Still, they are out there, shaping habitat that some birds and people can enjoy.
Whole Earth and Watershed Festival
Now in its 8th year, the Whole Earth and Watershed Festival takes place at Redding City Hall and Sculpture Park where Wintu Audubon will have a booth. The purpose of the festival is to increase awareness of what it will take to live more sustainably as individuals and as a community within our ecosystem, better conserve and appreciate our natural resources, and foster support of our local businesses and community agencies
Bear Creek Watershed Outing and Bird Survey
A rare chance to bird on private property! Wintu Audubon President Esther Cox belongs to this watershed organization and has interested property owners in learning the bird species that live on their spreads. We will visit several of them. Meet at the parking lot across from Shasta Regional Medical Center, behind Mary’s Pizza Shack, to carpool at 7:30 am or join Esther at the Share-A-Ride parking lot at the intersection of Hwy.44 and Black Butte Road at 8:00 am. This will be a full day trip, so bring a lunch and water.
Local Weekday Bird Walk to Reading Island
Located at the confluence of Anderson Creek and the Sacramento River southeast of Anderson off Balls Ferry Road, this open space is managed by the Bureau of Land Management. It features magnificent valley oaks, grasslands, riparian areas and secluded backwaters all within a small area. This variety of habitats should provide for a good morning of birding. We will gather as usual in the parking lot south of the Redding Civic Auditorium for this 1/2–day trip. Bill Oliver will lead.
