Day in a Life of a Point Counter

By Sam Webb

Lava Beds National Park by Sam Webb

There were still a few stars in the sky when I hit the trail, but the horizon was starting to lighten, and it promised another beautiful sunrise. I hiked for about 20 minutes, listening for any late owls calling or the Common Nighthawks announcing the dawn with their distinct Peent! sound. Checking my GPS, I walked another few meters before setting down my backpack and pulling gear out. Although no landmarks are around, I had just reached the first point that I will be surveying for the day.

For the past several weeks, I have been living in the gorgeous Lava Beds National Monument in Northern California to conduct avian monitoring surveys for Klamath Bird Observatory. The point that I have just stopped at is part of a point count route that has been visited every three years since 2007 as part of a collaboration between the Klamath Inventory and Monitoring Network and Klamath Bird Observatory. Point counts are a widely used method for surveying birds where observers visit specific locations or points and count every bird they detect within a standardized period of time. These surveys usually take only a few minutes to complete, meaning that observers can collect data at many locations in a single morning. Data from point count surveys are frequently used to determine changes in bird populations over time, which are often linked to environmental changes and may be used to inform land management practices.

I finished filling out the top of the data form on my clipboard, set up my timer to beep once every minute for five minutes, and positioned my binoculars to be easily accessible. Just a few moments before I began the survey, I used my laser-rangefinder to determine the distance to some of the juniper trees. Then, 15 minutes before sunrise, I hit start on the timer and began to listen intently.

All around me, the birds are waking up and starting their morning chorus songs. I furiously write down a Morning Dove that is singing near one of the trees I had measured the distance to, about 32 meters away. I watched a couple of Lark Sparrows chase each other between the rocks, and just as I finished writing them down, a Western meadowlark began its echoing song. I write almost nonstop for 5 minutes, pausing only to tune into a new song or briefly glance through my binoculars at a bright male California Quail perching on a nearby sagebrush. The timer beeps one last time at me, and the survey is done. I reviewed the datasheet before selecting the next point in the GPS and setting it off. I had 11 more points to visit and wanted to get to them before the bird activity slowed down for the day.

After reaching the 12th and final point, I perched on a rock, overviewing the valley, eating my lunch, and admiring the park. Slowly, I make my way back through each point I just visited, recording data on the habitat, identifying what shrubs and trees are present, and taking notes on the composition of forbs and grasses. When I was finally done, I reviewed the data from the day. Some highlights were a pair of Bullock’s Orioles that were busily weaving together their nest, a stunningly brilliant Mountain Bluebird that started his song almost before any other birds were up, and a Pinyon Jay that swooped by, curious about what I was doing out there. I finished packing up and began to head back to my vehicle. Done for the day, I took my time hiking back, pausing to enjoy the park and wildlife all around me. The data I collected will be provided to the Klamath Inventory and Monitoring Network to help inform decisions on management practices so that this gorgeous park can continue flourishing and support a vast host of plant and animal life.

The Klamath Inventory and Monitoring Network is a group of six national parks in the southern Oregon and northern California region that works to provide reliable scientific information about the parks and their key resources to park managers, researchers, and visitors.

SCIENCE BRIEF: KBO Researchers Study the Effects of Climate on Hawaiian Birds and Their Food Webs

Written by KBO on . Posted in Klamath Call Note, Conservation, KBO Science.

Native Hawaiian birds are renowned for their beauty and unique evolutionary history, where numerous species rely on native plants for food in the form of nectar and fruit. Many of these important native plants that provision food for birds rely on climatic cues – such as rain and temperature – to time their flowering and fruiting activity. Understanding how birds respond to climatically-induced changes in their food web represents an important step towards predicting the effects of climate change on vulnerable wildlife species.

To better understand these complex relationships, Klamath Bird Observatory research associate, Dr. Jared Wolfe, and KBO research advisor, Dr. C. John Ralph, used data collected from the Big Island of Hawaii to measure long-term relationships between changes in climate, fruit and flower production, and the timing of breeding and molting in native and non-native birds. Their results were recently published in the scientific journal Ecology in a paper titled “Bottom-up Processes Influence the Demography and Life-cycle Phenology of Hawaiian Bird Communities”.

“Flower and fruit abundance at our study site were strongly affected by seasonal changes in rain, which had cascading effects on the timing of important lifecycle events of birds, such as breeding seasonality”. says lead author Wolfe. “Our results suggest that changes in climate can cascade up the food chain and strongly affect wildlife at higher trophic levels.”

Results from the analysis suggest that three native birds that commonly feed on nectar, the ʻiʻiwi, ʻapapane and Hawaiʻi ʻamakihi, all timed their breeding season with the availability of ʻōhiʻa lehua flowers, which in-turn, used heavy rains to time flowering activity.

“Our project is one of the first from Hawaii to combine long-term climate, plant phenology and bird monitoring data to disentangle these complex trophic relationships” says co-author Ralph. “These types of studies are rare because they rely on long-term and labor-intensive field work. But, findings from long-term studies such as this one are critically important because they provide insights into how changes in climate might affect native Hawaiian birds.”

SCIENCE BRIEF: Bird Communities in the Klamath Ecoregion

People spend a lot of time watching birds, and scientists are no exception. Because birds use such a wide variety of resources and respond quickly to environmental change, they are gold mines of information. Even better, most species are easy to find, especially in the spring when they are singing! Scientists from Klamath Bird Observatory, the Klamath Inventory & Monitoring (I&M) Network and others used a wealth of bird data from the Klamath Ecoregion to understand how birds naturally group themselves across the landscape. Their results were just published in PLOS ONE, “Bird Communities and Environmental Correlates in southern Oregon and northern California, USA.”
