Golden-crowned, White-crowned, and Fox Sparrows arriving en mass from the north! Hermit Warblers and many other local nesting birds departing for their Tropical winter homes! And Sharp-shinned Hawks chasing them all through the forests! What a sensational dramatic story unfolding at our bird banding stations in these early days of the great annual bird fall migration! And you are invited to bear witness from a catbird seat with KBO’s biologists.
Klamath Bird Observatory continues to offer public visits to bird banding at our Upper Klamath Field Station near Fort Klamath in the Upper Klamath Lake area—but there are just a few more opportunities this fall. The banding station is scheduled on most Thursday mornings through mid-October. Individual, family, and group visits can be arranged by emailing KBO’s Banding Program Coordinator Bob Frey (see below).
This banding station, along Sevenmile Creek on the Fremont-Winema National Forest, is one of the longest running bird monitoring sites in the region. In the fall, many songbird species migrate through the Klamath Basin and can be encountered here, especially large numbers of warblers and sparrows. The location is also a birding hotspot on the Klamath Basin Birding Trail.
And a reminder … Crater Lake National Park and KBO continue our bird ecology program series into the fall. These Park Ranger-led programs begin at the Park’s Steel Visitor Center and feature a visit to KBO’s banding station in nearby Munson Valley. These programs are scheduled on Friday mornings—please check the Crater Lake National Park series flyer below for upcoming dates and more details.
Don’t miss these opportunities to experience the grand drama and visit KBO’s biologists and the birds they are studying up close!
Jaime Stephens, Klamath Bird Observatory (KBO) Science Director, will be presenting at the September 10th Klamath Basin Audubon Society meeting. The presentation will include an overview of KBO’s long-term monitoring and applied ecology research. It will focus on current projects occurring in the Klamath Basin within the context of broader bird conservation. An overview of long-term monitoring will include KBO’s bird banding program, monitoring in the National Parks, and a new long-term monitoring program initiated this spring in shrub-steppe habitats. The presentation will also highlight species-specific studies examining Vesper Sparrow, Black-backed Woodpecker, Common Nighthawk, and Hermit Warbler. The Hermit Warbler research is a partnership with Oregon State University which aims to better understand migratory connectivity for this species, to elucidate potential causal factors in population trends and inform conservation actions. The Klamath Basin was one of nine study sites where Hermit Warblers were tagged with geolocators in spring of 2019. This project aligns closely with the KBO-led Western Warblers Initiative, which seeks to apply the latest technology (Motus) in expanding our knowledge of migratory movements and connectivity for warblers; research will begin on Hermit, Wilson’s, and Black-throated Gray warblers in spring of 2020. The presentation will include time for questions and discussion about these projects and broader bird conservation initiatives.

Managers charged with stewarding public and private lands strive to protect, maintain, and restore healthy forest conditions that are resilient to drought, flood, and severe wildfire. Managers often rely on the presence of indicator species and species richness (i.e., the number of species present) to assess the value of different forest conditions to wildlife; however, relying on an indicator species or estimates of richness does not directly measure in what way focal habitats support the life history needs of individual species. For example, a bird provisioning food to nestlings is a more meaningful metric than a bird of the same species simply dispersing through a focal habitat. Unfortunately, classical measures of richness often treat these two hypothetical birds as similar when assessing the value of forests to wildlife. While past conservation planning has largely focused on wildlife presence, new research suggests assessing habitat value throughout the entire avian life cycle will provide a more holistic approach to management.
Recognizing the need for a better assessment of forest value to wildlife, a team of researchers from Klamath Bird Observatory, the Forest Service, and Michigan Technological University developed the “informed indices” concept. This new and impactful method scales diversity estimates by meaningful phases of each species lifecycle, such as breeding and feather replacement (i.e., molt). For proof-of-concept, the collaborative team used 18 years of bird capture data from across multiple forest types in California and Oregon to determine how measures of diversity change for bird communities across the breeding and molting seasons.
“We were surprised to find that forests with diverse breeding bird communities sometimes hosted relatively depauperate molting communities, demonstrating that a single location’s value is dynamic, changing from high to low depending on what part of the avian lifecycle a manager is considering” said Dr. Jared Wolfe, Klamath Bird Observatory Research Associate and lead author of the study.
“Instead of relying on simple measures of presence and absence, our informed indices concept assesses wildlife across biologically-meaningful seasons. This is an important improvement because it identifies essential variation in the value of forest to wildlife, thereby allowing managers to properly conserve wildlife throughout North America and beyond” said Dr. John Alexander, Klamath Bird Observatory Executive Director and co-author of the study.

The study of natural areas can improve our understanding of plants and animals that occupy different habitats. Land managers need this kind of information for making decisions about how best to manage, restore, or protect their lands. However, it is not possible to measure each aspect of biodiversity. Studying one or several species to better understand the natural area as a whole is a common, but relatively understudied, practice. In the Pacific Northwest, Partners in Flight – a broad partnership aimed at conserving bird populations – has been using birds as focal species for nearly 20 years. The premise is that a suite of songbird species that are closely tied to key habitat features will represent many other bird species and other elements of biodiversity.
New research examines the focal species approach
Scientists from Klamath Bird Observatory and the Klamath Inventory and Monitoring Network of the National Park Service teamed up to think about how the focal species approach is being applied to six national parks in southern Oregon and northern California. Specifically, we examined whether the Partners in Flight focal species, which are derived from expert opinions and knowledge of birds and their habitats, did a good job at representing three additional management concerns: 1) vegetation, 2) other songbirds, and 3) more specifically, songbirds in decline. We then tested whether we could develop a focal species list from existing park-specific bird surveys that would do a better job at representing the other groups. The results were recently published in the scientific journal Ecological Applications in an article titled Established and Empirically Derived Landbird Focal Species Lists Correlate with Vegetation and Avian Metrics(CLICK HERE TO SEE THE PUBLICATION).
Why does this matter?
If focal species do a good job at representing other groups of birds or vegetation, then the list can help land managers make better decisions about natural areas. Deciding which correlations are most important will depend on the management question at hand. For example, with vegetation management, if focal species are highly correlated with other songbirds and vegetation, managers can confidently apply their knowledge about the focal species to planning needs, such as developing a restoration strategy.
What have we learned?
Partners in Flight focal species represented three other components of biodiversity (all songbirds combined, songbirds in decline, and vegetation) in some, but not all, instances. We found that the Partners in Flight focal species did a good job of representing other songbirds at four of the six national parks. For all parks combined, the focal species developed from park-specific bird surveys improved correlation, showing the most notable improvement at Crater Lake National Park, where the existing focal species did not correlate strongly with the other groups. In contrast to the close association with songbirds generally, the Partners in Flight focal species lists represented songbirds in decline at only two of the parks. It is likely that species in decline have different habitat needs or experience different threats than the focal species.
Partners in Flight focal species lists are based on breeding season habitat needs, but food and habitat outside of the breeding season are also critically important for birds. For example, understanding how seasonal habitat and food needs relate to songbird health and ability to produce young, and how climate interacts with those, may inform conservation of declining species. Adding focal species that can represent limitations or threats outside of the breeding season may expand the use of this approach in the context of widespread bird population declines. Further, continued long-term monitoring in the parks is critical to understanding both whether local bird populations show similar dynamics as the same species at regional and national scales, and if so, the reasons why.
Ashland, OR – A new study on songbirds in the Pacific Northwest, released on March 11th, empirically tests the use of focal species as indicators of ecosystem health.
Focal species are often monitored to understand overall ecosystem health and thereby inform and improve natural resource management. However, few studies have empirically tested how well this approach works. The new study, Established and empirically derived landbird focal species lists correlate with vegetation and avian metrics, published by scientists at Klamath Bird Observatory and the Klamath Inventory and Monitoring Network of the National Park Service, tested the focal species approach against site-specific empirical data and found that a suite of bird focal species represented other birds and vegetation in some, but not all instances, and the application of focal species may be improved with more site-specific data.
In the Pacific Northwest, Partners in Flight (PIF) – a broad partnership aimed at conserving bird populations – has been using birds as focal species for nearly 20 years. The premise of the focal species approach is that a suite of songbird species that are closely tied to key habitat features will represent many other bird species and other elements of biodiversity. The study, published in the scientific journal Ecological Applications (CLICK HERE TO SEE THE PUBLICATION), used data from six national parks in southern Oregon and northern California to evaluate the focal species approach in the Pacific Northwest. Specifically, the study examined whether PIF focal species represented three broader ecosystem components of biodiversity: vegetation, other songbirds, and more specifically, songbirds in decline. The researchers then tested whether they could develop a focal species list from existing park-specific bird surveys that would do a better job at representing the broader suite of species and vegetation.
“If focal species do a good job at representing others aspects of biodiversity, then we can confidently apply them to decisions about managing natural areas. In this time of unprecedented human altered environments, ensuring that the best available science informs decision-making in an efficient manner is crucial,” explains Jaime Stephens, KBO’s Science Director and lead author of this paper. Jaime suggests that this study identifies not only how this approach can be useful to land managers, but importantly, also the limitations of the focal species approach.
The research team found that PIF focal species represented the broader suite of species and vegetation in some, but not all, instances. For example, Partners in Flight focal species did a good job of representing other songbirds at four of the six national parks included in the study. For all parks combined, the new focal species developed from the park-specific bird surveys were slightly better at representing other songbirds, with more improvement in some parks than others.
In contrast to the close association of focal species with the group of all songbirds combined, the PIF focal species represented songbirds in decline at only two of the parks. John Alexander, KBO Executive Director and a co-author of the study, highlights that “It is likely that the species in decline experience different threats than the focal species.” Alexander goes on to explain that these underrepresented declining species may face threats when they leave the parks during the migration – the focal species are chosen to help understand conditions in each park where the songbirds breed.
“I’ve worked through many uses of indicator and focal species approaches as a way for us to “see” and perhaps improve how a system works, and this is among the best approaches I know,” says PIF National Coordinator Bob Ford. He adds, “This approach provides a blueprint for how multi indicator species can be applied to advance conservation in other North American biomes.” He believes this is an important part of the PIF toolbox, adding value to the full lifecycle approaches that PIF applies to addressing conservation needs for priority and declining species.
This study, funded by the National Park Service Inventory and Monitoring Program, takes advantage of the first decade of long-term bird monitoring in the six national parks of the Klamath Network. This monitoring program was designed to answer pressing questions for park managers and local conservation practitioners over the short-term, while monitoring long-term trends in bird populations over the long term. “Our long time partners at KBO provide valuable expertise that allows us to extend the value of our datasets and answer important questions that support natural resource stewardship in Klamath Network parks and beyond,” says Alice Chung-MacCoubrey, the NPS Klamath Network Inventory and Monitoring Program Manager. Continued long-term monitoring in the parks is critical to understanding local bird population dynamics in comparison to trends for the same species at regional and national scales.

About Klamath Inventory and Monitoring Network of the National Park Service: The Klamath Network tracks the ecological health of six national park units in southern Oregon and northern California. We inventory park natural resources and then regularly monitor the condition of a carefully selected subset, called “vital signs,” at Crater Lake NP, Lava Beds NM, Whiskeytown NRA, Lassen Volcanic NP, Redwood National and State Parks, and Oregon Caves National Monument and Preserve. Our small staff of scientists partners with park scientists and other organizations to monitor nine vital signs: cave environments and communities, rocky intertidal zone communities, landbird communities, land cover and use within and surrounding parks, lake water quality and aquatic communities, stream water quality and aquatic communities, vegetation communities, invasive plants, and whitebark pine trees.

Riparian (or streamside) habitats are critical for water quality and wildlife. These habitats filter pollutants from runoff, stabilize soils, provide shade to cool water temperatures, and much more. They are also known for their biodiversity, supporting the most diverse bird communities of any habitat type in arid and semi-arid regions such as ours. This is even more pronounced in urban landscapes.
Some of our most at-risk bird species require riparian habitats for breeding. Many species also need healthy riparian habitats during the fall and winter seasons, when they complete important activities like refueling during migration, replacing worn feathers (molting), or building reserves for the next breeding season.
Most of our western riparian habitats have been lost or degraded due to human impacts. However, restoration efforts are helping to return these areas back to more functioning natural conditions. For nearly two decades Klamath Bird Observatory, Lomakatsi Restoration Project, and Ashland School District have partnered on a riparian restoration project at the Willow Wind Community Learning Center along Bear Creek in Ashland, Oregon.
Lomakatsi works to improve riparian habitat in our region by planting a wide diversity of native vegetation, removing invasive plants, and supporting the natural regeneration of native plant communities. As part of the project at Willow Wind, over 3,000 native trees and shrubs have been planted by Lomakatsi’s restoration workers, school groups, and community volunteers. This work has increased the size and health of riparian areas that cool and clean our water, while also providing important bird habitat.
KBO has studied birds as indicators of habitat quality at Willow Wind over the past 18 years to monitor the effectiveness of this streamside habitat restoration. The abundance of several bird species that use riparian habitats during the winter has increased over time in areas where Lomakatsi implemented restoration efforts. The abundance of these same species changed less in areas where no restoration occurred. Before restoration actions took place, the fall bird community at Willow Wind was substantially different than that of nearby mature riparian habitat. In the restored areas, the fall bird community is now becoming more similar to the bird communities in mature riparian habitat along Bear Creek, as a result of the regrowth of native plants. Restoration actions are improving riparian habitat quality in areas where it had previously been degraded.

KBO’s new Decision Support Tool highlights recent studies from KBO scientists and partners and demonstrates how we used science and birds as indicators to inform an adaptive management process in the Monument. The Monument was created to protect biodiversity, including migratory birds that need protection to prevent or reverse recent population declines. The Monument’s establishment, and its expansion in 2017, provided increased protection for critical habitats that many priority migratory bird species need, including oaks and grasslands that are among the most at-risk habitats in the western United States. When the Monument was established KBO completed a study that demonstrated measurable impacts of livestock on the Monument’s migratory birds. Results from this and other studies informed a process to eliminate livestock grazing from most of the Monument. KBO then did a follow up study that showed the measurable benefits of removing cattle from the Monument for migratory birds in oak woodlands.
Like KBO’s other Decision Support tools, this new four-page document is intended for managers, conservation resource professionals, and anyone else that is interested in how science can be used to make natural resource management decisions and measure the effectiveness of management actions that incorporate bird and habitat conservation objectives.

Forests in the Klamath Mountains Ecoregion, centered within the core of Klamath Bird Observatory’s focus region, are home to a diversity of wildlife, including birds. While old-growth forests receive a lot of attention, species such as Black-throated Grey Warblers, Rufous Hummingbirds, and Olive-sided Flycatchers all use habitat features of younger, early-successional forests, such as broad-leafed trees and shrubs, edges, or snags.
Because most of the early-successional forest in our region is privately managed, Klamath Bird Observatory recently worked with several partners to identify conservation opportunities for birds in southern Oregon’s private timber stands. With support from the Sustainable Forestry Initiative, we worked alongside the American Bird Conservancy, the National Council for Air and Stream Improvement (NCASI), and private forest management companies (Hancock Forest Management, Weyerhauser, and Lone Rock Forest Resources) to learn more about how privately managed timber stands can provide habitat for birds.
One of the main goals of the project was to identify opportunities for improving early-successional forest bird habitat on privately-managed timber forests, and asking what management practices might make those habitats of greater value to birds. As a first step, we produced a scoping document titledSustainable Forest Management: Opportunities for Bird Conservation on Private Timberlands in the Klamath Mountains, Oregon. It identifies focal bird species and habitat features that are important in the early successional forest of our region. This document compiled information from forest bird conservation plans and identified potential management action on private lands that would benefit many of those bird species.
The next step was to study how bird species use private forests in southern Oregon, and how different characteristics of timber stands contribute to habitat quality. To do so, we used species distribution models (SDMs), developed from 16 years of bird survey data from across the Klamath Mountains Ecoregion. Our unique SDMs use historical bird survey data and unclassified land cover imagery to develop a mathematical model that can be used to predict where species will occur on a landscape (See Using Birds to Predict Habitat Conditions for more information about our modeling approach). One of the advantages of using a model to predict bird habitat is that it allowed us to identify and rank the bird habitat potential for a large number of privately managed timber stands on the landscape. While KBO did field work on a small sample of those stands to check the models, our research using KBO’s larger region-wide dataset was ultimately able to provide information about bird habitat on over 2,100 privately managed forest stands in the region!
Finally, to learn more, we conducted two workshops with forestry professionals to understand how management can create high-quality early-successional habitat for birds. We visited some of the stands, talked about the results from our research, and discussed the management that may have contributed to how different timber stands ranked in our analysis. The workshop led to some successful conversations about practices that can be easily incorporated into existing forest management plans to create habitat for birds. Our workshops and research ultimately led to the development of two factsheets that highlight some of the key opportunities for bird conservation in private timber stands in our region. We’ve compiled the resources from this project as a manager’s guide on Avian Knowledge Northwest. Click here to read more and to download the factsheets!
