Conservation Priorities

2020 Conservation Priority Goals of the Oregon Audubon Council

Annually, Oregon’s Audubon Chapters meet and determine shared issues, concerns and opportunities that we can work on together and influence in the coming year. Conclusions are listed below, grouped and underscored without order of priority, and again do not include other priorities of individual Chapters. Some issues, like general opposition to the Jordan Cove LNG plant and associated pipeline as an example, may fall under another statewide priority without compromising the interest of an individual Chapter with opposition to only a specific portion of the project.

  • Insure greater protection for ocean and forests
  • Defend federal lands and laws
  • Provide guidance to Klamath and Malheur Wildlife Refuge management
  • Special attention for bird species: Marbled Murrelets, Greater Sage-grouse, California Condors, Streaked Horned Larks
  • Greater attention statewide for the importance of beavers to ecosystem function
  • Recognize the importance of ODFW reform and funding for protection of bird species, updated policies for trapping beavers, and judicious methods of predator control
  • Tackle climate change both locally and statewide
  • Recognize the impact of the Columbia River Hydropower System on aquatic life and all species dependent on its health
  • Address light pollution through the Dark Skies Initiative
  • Deter bird mortality from window strikes

Swifts

Vaux's swift
Vaux’s Swifts may look similar to swallows, but they have a cigar-shaped body, longer, more arched wings, and a shorter tail.

Swifts are the most aerial of birds, spending most of their lives on the wing—foraging for flying insects, skimming water from the surface of ponds, mating in midair, and sometimes even sleeping on the wing. Two species occur regularly in western Oregon, both with specialized requirements for the non-airborne parts of their lives. The larger of the two species, Black Swift (Cypseloides niger), nests on rock cliffs behind waterfalls, and only a few regular nesting locations have been found in Oregon. Black Swift is classed as Endangered with key threats believed to include airborne pollutants that reduce aerial insect availability and climate change that could reduce and/or disrupt the seasonal timing of stream flows at waterfalls.

The smaller species, Vaux’s Swift (the first part of the name rhymes with “boxes”) (Chaetura vauxi) is comparatively well-known due to its tendency to use chimneys as roosting and nesting sites. As with its eastern cousin the Chimney Swift, this is an adaptation to large-scale loss of the old-growth forests where large, dead hollow trees once served this function. Much of the population now depends on man-made structures, especially along their southbound migration route through logged and urbanized areas. (Joel Geier)

Trumpeter Swans

trumpeter swans
Trumpeter Swans are not a federally listed species but are still recovering from near extinction and only found on one third of their original range.

Tundra Swans (Cygnus columbianus) and Trumpeter Swans (Cygnus buccinator) winter in our area. Tundra Swans are smaller, far more common, arrive earlier and stay later, and congregate in huge flocks at mid-valley refuges. Trumpeter Swans are the largest wild bird species by weight in North America, with a wingspan close to that of eagles. In our area, wintering Trumpeter Swans typically arrive in mid- to late November and stay through February.

Historically Trumpeter Swans nested across the continent from Alaska to New England and south to the Rio Grande. Early accounts from Oregon suggest that this species was more abundant than Tundra Swans in the mid-1800s. However the population was decimated by hunting for meat, millinery feathers, and skins almost to extinction until a tiny, nonmigratory population was discovered in the Yellowstone area. In 1968 there were still only 3,700 Trumpeters, and in 2015 the population had climbed to 63,000. Although this is an incredible increase, Trumpeter Swans are still missing from nearly two thirds of their original range. Conservation threats include loss of winter habitat, collisions with utility wires, and lead poisoning. Trumpeter Swans are currently Not Listed on the federal Endangered Species List, and no critical habitat or conservation plans are in effect.

Marbled Murrelets

marbled murrelet
Marbled Murrelets are listed as Endangered federally and Threatened in Oregon and Washington.

Marbled Murrelets (Brachyramphus marmoratus) are stout seabirds that are related to puffins. Their range is from coastal Alaska to Baja. The species was first described in 1789, but it was not documented until 1974 that they nest high in old-growth trees. The birds are secretive, nest singly – not in colonies, and both parents only fly inland at night to feed chicks.

Most of the year you can find Marbled Murrelets near the coast on quiet bays or occasionally on coastal lakes. They do not form flocks, rather they are in pairs, spending most of the day foraging in shallow water for small fish and crustaceans. When startled, they fly away from the noise with very fast wingbeats.

Since the 1850s, their population has declined 50 – 80% as nesting habitat is logged and fragmented. Marbled murrelets are also threatened by oil spills near their foraging areas. They are listed as Threatened federally and Sensitive in Oregon. Oregon State University’s College of Forestry began a study in 2015 to understand the nesting needs and preferences of Marbled Murrelets. Researchers tag up to 100 breeding murrelets with tiny transmitters every spring, Ultimately the researchers plan to advise forest managers about factors that affect nesting success.

Vesper Sparrows

Vesper Sparrows (Pooecetes gramineus) were named because it was thought their melodious song sounded best in the evening. They live in open grassy fields or prairies, foraging for insects and seeds on bare ground around weed clumps. They often dust-bathe on dirt roads or tilled fields. Males defends nesting territory by singing from a perch on a taller plant, while females often mimic an injury to lure an intruder away.

A scientific study is underway to examine two potential factors that may be contributing to Vesper Sparrow population declines: 1) survivorship (Are birds returning after their migrations and wintering?), and 2) recruitment and dispersal (Is there movement of birds between local sites, and if so how far and what are the conditions that facilitate that exchange). Knowledge gained from this effort will help to target how and where to direct conservation actions for recovery.

Greater Sage-Grouse

Greater sage-grouse
Greater Sage-Grouse are found in 13 western US states and three Canadian provinces. The males puff up to a spherical shape on the lek as they display for potential mates.

Greater sage-grouse (Centrocercus urophasianus) are the most visible of >350 plant and wildlife species that depend on sagebrush. Their conservation status was determined by the U.S. Fish and Wildlife Service in 2010 to be Warranted for Listing but Precluded by Higher Priorities. Habitat and population fragmentation, coupled with inadequate regulatory mechanisms to control development on public lands, were the primary factors in the listing decision. Approximately 70% of the current sagebrush distribution within the greater sage-grouse range is public land; the U.S. Bureau of Land Management is responsible for managing half of the sagebrush within the United States. Less than 1% of the sagebrush is within areas protected from land-cover conversion. The remaining public land is managed for multiple uses that include livestock grazing, energy development, and recreation.

Managers have emphasized sage-grouse as indicators of ecosystem health. … Therefore, research is focused on gaining a better understanding of how sagebrush and sage-grouse populations are temporally and spatially interconnected. These relationships then can be significant factors in developing conservation actions that enhance the long-term viability of sagebrush ecosystems. (US Geological Survey project)

California Condors

California condor
California Condors are currently listed as federal Threatened species.

A holdover from prehistoric times, the California Condor (Gymnogyps californianus) is one of our largest and most magnificent birds – and one of the rarest. Soaring over wilderness crags, feeding on carcasses of large dead animals, and reproducing very slowly, condors were not well suited to survival in modern-day southern California. Headed toward extinction in the 1980s, the last birds were brought in from the wild in 1987, to be bred in captivity for eventual release into the wild again. The captive breeding program turned out to be surprisingly successful, and flocks of released condors are surviving in several areas of California and in the region of the Grand Canyon.

Condors roost mornings and evenings and soar on wind currents to forage for carrion during the day. They may find much of their food by watching actions of other scavengers, such as vultures or ravens. Only one egg is laid, and parents trade incubation duties once every 1 – 5 days. Young are capable of flight about 5-6 months after hatching, but may remain dependent on parents for another 6 months. This means that the whole nesting cycle takes more than a year, so condors breed every other year. (National Audubon Society)

Current threats include carcass poisoning and lead ammunition, shooting, and collisions with power lines.  California Condors are federally listed as Endangered. Because their range included Oregon, it is a possibility that reintroduction in the state is possible in the future.
