As one leaves the town of Jackson and heads north on HWY 89, a trail of nestboxes lines the fencing of the National Elk Refuge. These nestboxes are part of JHWF’s Mountain Bluebird Nestbox Monitoring Project, which is designed to mitigate for extreme habitat loss that has negatively impacted the breeding success of this species. Monitoring work has been conducted for the past 13 years, but this summer we added a new element to the project by hiring bird bander Allison Swan. With help from our volunteers, Allison has banded 98 chicks and 1 female adult since May.
With data collected through banding and the re-sighting of individuals, we will be able to evaluate survival rates of young, dispersal patterns, re-nesting rates, productivity by age, site fidelity, and other measures of population dynamics. This type of information will allow us to understand population status in Jackson Hole and to better inform land management decisions with respect to the Mountain Bluebird.
Almost all chicks born this summer have fledged their nests and now is the time to begin searching for our color-banded birds — 99 in total.
Already several banded birds have been re-sighted through the use of binoculars and spotting scopes. Our first sighting was a juvenile Mountain Bluebird who crossed the highway and was seen in the parking lot of the National Museum of Wildlife Art. Fledglings can fly quite well, but many are still being fed by the adults, which means they will often stay in place long enough to get a good look at colored-bands on their legs.
All Nature Mappers, we need your help re-sighting banded bluebirds! The most important data we need collected is location data and the color band scheme for each bird. Ideally, we would also like to collect additional data on behavior, substrate and plumage.
The color bands are noticeable and folks have been reporting that it is easy to read the colors, especially with use of binoculars. If you do not have binoculars, please stop by the Jackson Hole Wildlife Foundation office and borrow a pair! We have three scopes and two pair of binoculars for volunteers to borrow while conducting observations.
Download our Re-sighting Datasheet here. As you observe and record sightings of this year’s birds note each ones unique color combination. Datasheets should be given to our Associate Director, Kate Gersh at: Kate@jhwildlife.org. We also encourage the sharing of verbal reports by calling our office at: (307) 739-0968.
Thanks for the help!
