Bird Banding: Monitoring Avian Productivity and Survivorship (MAPS) Project
In 1991, the Teton Science School’s Teton Research Institute began banding songbirds within the boundaries of Grand Teton National Park. Using the Institute for Bird Populations’ Monitoring Avian Productivity and Survivorship (MAPS) protocol, banders have collected data including age, sex, breeding status and body condition from over 10,000 songbirds at this and four other sites. With the help of scientists at both the TSS Teton Research Institute and the Teton Raptor Center we have a continuous data set that extends up to 27 years!
During the summer of 2017, JHWF had the pleasure of working alongside scientists from the Teton Raptor Center in order to become familiar with the specifics of running the MAPS stations in Jackson Hole. Between the two stations, we captured 577 individual birds of 43 species.The five most commonly captured species were:
- Yellow Warbler (118)
- American Robin (64)
- Song Sparrow (53)
- MacGillivray’s Warbler (50)
- Cedar Waxwing (32)
Beginning in 2018, JHWF staff and volunteers will be leading banding efforts at both MAPS stations — the original station in the park as well as a station located on private land, west of Jackson. We hope to be able to contribute ongoing data for the next 27 years and beyond!
What is MAPS?
The MAPS, or Monitoring Avian Productivity and Survivorship, program is a cooperative effort to collect standardized data on North American landbirds. In doing so, we are able to recognize and monitor long-term trends in avian populations and, ultimately, identify factors that can lead to changes in those populations.
By increasing our understanding of these factors and their relationships, from a local to a continental scale, we are able to make informed conservation and management decisions. Furthermore, we will be able to measure the effectiveness of those decisions once they have been put into action.
Factors Influencing Avian Population Change:
- How successfully the population produces young (productivity)
- How long birds live (survivorship)
- How many young birds survive into adulthood to produce nestlings of their own (recruitment)
- Habitat change
- Climate change
MAPS stations use mist nets, placed at permanent locations within a designated study area, to safely capture birds. Banders extract the birds from the nests and bring them back to a centralized location, where they take various measurements and place a USGS-issued aluminum band on the bird’s leg prior to releasing it.
Banding begins around sunrise and the nets are open for six hours during one day of every 10-day period. The season begins in May or early June, depending on latitude (that’s the first week of June for us, in Jackson Hole!) and runs through early August.
Note: Banders are trained and operate under special permits in order to handle wild birds. The safety of each and every bird is our priority and we are constantly checking in on the bird’s condition during the banding process.
Why Study Birds?
You mean, other than because birds are awesome?
You’ve probably heard the phrase “the canary in the coal mine.” Throughout most of the 1900s, canaries were used in coal mines as an early indicator of the presence of carbon monoxide and other toxic gases. By observing the activity of the canaries, the miners were alerted if conditions became unsafe and they needed to evacuate. In a similar way, birds serve as “sentinel animals” of environmental health.
Birds eat other organisms, whether seeds and berries or other animals (insects, rodents, even other birds), which they metabolize fairly quickly. Because of this, birds can bio-accumulate toxins and other compounds present in the organisms that make up their diet. In this way, the health of birds directly correlates to the health of the broader ecosystem. What’s more, birds are the most successful terrestrial vertebrate — they live on every continent and occupy a wide variety of habitats. They are active during the day and often easily heard and seen, making them easier to study than most other animals.
Plus, who doesn’t love birds?

The MAPS program began in 1989, with 16 stations throughout the United States. Now, there are over 1300 MAPS stations in nearly every US state and Canadian province. The resulting data set exceeds 2 million avian captures!
Here in Jackson, our sites have been in operation for 27 years (Kelly) and 15 years (Jackson).
Why is it important to have long-term data?
According to the National Science Foundation (NSF), long-term research is important because:
- Changes in many ecological processes occur slowly
- Impact of relatively rare events can only be assessed when ongoing studies have been conducted
- Ecological processes vary from year to year and patterns can only be discerned from a long-term view
- Long-term studies provide a context in which shorter-term studies may be understood
