This past Saturday, May 19, 2018, JHWF staff participated in the annual Wyoming Game & Fish Department bird survey of the South Park Wildlife Habitat Management Area, just south of Jackson. Our group of volunteer birders, including enthusiastic Nature Mappers and Jackson Hole Bird & Nature Club members, met bright and early Saturday morning, led by our local bird nerd expert volunteer, Tim Griffith. Tim has been crucial to organizing Game & Fish bird surveys of the South Park area since 2016, which have so far logged 96 different species for the area! Our pack split into two groups, one to tackle waterfowl, shorebirds and raptors around the ponds, the other to take on “Warbler Alley,” the thick cottonwood tree groves hugging the backwaters of the Snake River to the southeast. What an appropriate nickname that was – Yellow Warblers dotted most every tree in South Park, and were joined by the radiant Yellow-rumped, Wilson’s and MacGillivary’s Warblers as well. It was a different traveler from the south, however, that took everyone by surprise.
‘Warbler’s neck’ is a common occurrence on a bird survey.
After a busy four hours of hiking and birding the survey was winding down, and brunch was on the brain. But birding tends to deliver the bombshells at the last moments, and Saturday was no different. Jon Mobeck, our team’s oriole-obsessed leader shouted. “Bullock’s! Wait… BALTIMORE!” In a low hawthorn tree not 50 feet from us, was not only a Bullock’s Oriole, a gorgeous but fairly common bird in Jackson Hole, but next to it was a Baltimore Oriole, a normally much more eastern cousin. Historical records vary, but this bird may be one of less than a dozen ever reported in the state of Wyoming, and likely less than a handful have ever been seen in Teton County. What a find! The Bullock’s and Baltimore seemed to follow each other, flying from tree to tree after one another. Perhaps the Baltimore had lost his way on his normal spring route up from Central America, noticed a bird that resembled his brilliant orange color, and followed that Bullock’s back to our western mountains, far away from his normal east-of-the-plains summer vacation.

It’s moments like these that make us realize how special close-to-home wild places like South Park are. The diversity of wildlife in these areas can be astounding. But problems exist in the fact that unless these places are studied or surveyed, we may never know the rarities or struggling populations there. This is the issue Nature Mapping Jackson Hole is helping to solve – by submitting data from your commute from work, a dog-walk in a Jackson city park or a backpacking trip through the Gros Ventre, you are helping to build our human community’s understanding of the wildlife community that surrounds us. And every data point really is significant! You don’t often find rare birds like the Baltimore Oriole, but it’s very possible that the deer you saw driving home could represent the beginning of a muley movement exploring a new feeding ground in Jackson Hole. The data you enter from these sightings help JHWF’s partners to prepare management decisions that inspire positive interaction between humans and the wildlife moving into these areas. Knowing that your effort can directly benefit our local species is a reward in itself, and who knows – maybe your attention to wildlife developed from Nature Mapping will lead you to that once-in-a-lifetime animal.
