Our MAPS bird-banding program is experiencing an eerily slow start to the 2021 banding year.
So far, we have captured 193 birds of 32 species. Of those 130 were newly banded, 47 were recaptures, and 16 left our hands unbanded.
Although we are only 7 species short of our total from last year, the overall numbers are fewer than in previous years. For example, on one morning we captured zero Yellow Warblers, which are typically our most numerous species (see what we banded in 2020).
This could be correlated with the mass die-off of migratory birds that occurred last fall in the southwest (https://www.audubon.org/news/the-southwest-facing-unprecedented-migratory-bird-die) and greater Western region.
We can’t say for sure what the cause is and we won’t know exactly how different this season was until we analyze our data. However, it has been interesting to experience what has seemed like an unusually slow spring migration and start to the breeding season.
Mountain Bluebird Nestbox Monitoring
Nature Mapping citizen scientists began another season of Mountain Bluebird nestbox monitoring on May 1st 2021. Our bluebird trail is comprised of 112 boxes mounted on the National Elk Refuge fence along Hwy 89. These boxes are monitored by 14 volunteers.
These hardy volunteers brave mud, ants, and empty nestboxes to ensure accurate and quality data collection along the bluebird trail. We are ever grateful for their good work!
This year, seven nestboxes have been occupied by Mountain Bluebirds and many more boxes are occupied by Tree Swallows and House Wrens. The first wave of bluebird nesting is almost over, but a couple bluebird pairs have already initiated new nesting attempts for their second broods.
JHWF is color-banding Mountain Bluebirds as a part of our effort to understand survivorship, dispersal, and site fidelity of the bluebirds in Jackson Hole.
This year we have banded 35 Mountain Bluebird nestlings and two adults that we caught opportunistically. We also color banded two Mountain Bluebird adults that we caught at our Boyles Hill MAPS banding station.
If you see a color-banded bluebird in or near Jackson, write down the color combination, note the location, and report the sighting to reportband.gov or Hilary@jhwildlife.org!

How long have you been involved in Mountain Bluebird Nest Box Monitoring and do you have an estimate for how many active bluebird nests you’ve monitored?
Patti – We first volunteered in 2018 and 2019. We watched a set of 10 nest boxes, in 2018 we had 3 nest boxes that produced little baby bluebirds – it was like magic to me. We witnessed 2 sets of nestlings being banded, one nest with 5 and the other with 6.
What drew you to be a Mountain Bluebird nest box volunteer?
Patti – My first thought was “Have you see the color of those birds? Who wouldn’t want to watch them.” But really, any chance to watch birds that close up through an entire breeding and nesting season was really exciting.
Do you a specific fond or rewarding memories related to this project?
Patti – I would say the first blue egg in box 15 did it for me. Also seeing them being banded was an amazing feat by the professionals
Are there any challenges/negative aspects of being a Mountain Bluebird nest box monitoring volunteer?
Patti – Being dive-bombed by the tree swallows was not fun. They are feisty creatures and do not like visitors to their nests close to egg laying time. It’s because you have both of them protecting their box! The other challenge is being about 3″ too short to see into some of the boxes. The pocket digital camera became my assistant if Andrew was not there.
Do you have any advice you would give to new Mountain Bluebird nest box volunteers?
Patti – Use your camera to record what you see. Even if no one needs the data in picture form, you yourself will be amazed to remember the whole process in such a clear way – from the first scraps of grass to the eggs appearing one by one, to the hatchlings then to the nestlings, and then on to the abandoned box.
What is it specifically about birds that draws your interest?
Patti – Andrew is a mammalogist by training and has been interested in nature all of his life. I was a girl scout from 2nd grade through adulthood. We both love the outdoors. Andrew’s interest in birds came as he was watching mammals! My interest was a bit delayed because I thought I would never be able to spot them quickly enough and make any sort of identification. As usual, his patient teaching methods and field identification hints helped me gain skills and he is still here to help me spot field marks and bird behavior. My first life-list bird was a raven in Logan, Utah in 1980.

Eagle Scout is the highest achievement or rank attainable in the Boy Scouting program of the Boy Scouts of America. The requirements necessary to achieve this rank take years to fulfill, and must include completion of an extensive service project that the Scout plans, organizes, leads, and manages. Luckily for the Jackson Hole Wildlife Foundation, prospective Eagle Scout Maclain Smith from Utah, made us the beneficiary of his service project. This past Friday afternoon, Maclain came up to Jackson to install 52 Mountain bluebird nestboxes that he and fellow Scouts constructed by hand.
With lots of laughs and great spirit, Maclain and nine of his family members spent a sunny autumn afternoon installing new pinewood nestboxes on half of our Mountain bluebird trail that runs along the western boundary of the National Elk Refuge. Our old nestboxes (that served their purpose for 13 years!) were taken to Teton Recycling Center where they will be repurposed into wood mulch and used for gardening and landscaping purposes. After 13 years, we felt it time to retire the old nestboxes as they had seen many repairs over the years, but their deteriorating condition was starting to present challenges in terms of predator control and protecting nests from bad weather conditions.
Not only are we fortunate to have the help of Maclain, but we currently have two more prospective Eagle Scouts producing a total of 72 additional nestboxes that will be installed this coming spring. Of these 72 — the other half of our trail will receive 52 new nestboxes, we are looking into placing additional nestboxes elsewhere on the National Elk Refuge, and keep a few in storage. Thank goodness for Scouts!

As a follow-up to last week’s blog post, unfortunately we have sad news to report. The nest with the five bluebird chicks seems to have been sabotaged and no observable signs exist of the chicks or their parents. Upon arriving at this particular nest box for weekly inspection, the top lid was haphazardly lying on the ground about a foot away; its screws that held it firmly in place were stripped from the wood and only just hanging on by wire. Scratch marks can be seen around the entrance hole. We can’t know for sure what happened, but we suspect we have a weasel hunting our mountain bluebird trail as other nature mappers have reported similar scenarios.
All we can do is remain vigilant to identify the predator and then devise an appropriate solution. It is a reminder to us of the nature of nature, and the circle of life in birth, survival and death — how all in nature are independent and interconnected. However, such involvement as ours through citizen science (while sometimes strongly tugging at our heartstrings) ultimately, still connects us with relevant, meaningful, and real experiences with science.
