Bluebirds should be visible at Grand Teton National Park on International Migratory Bird Day this coming weekend/NPS

As the calendar falls deeper and deeper into spring, more and more birds are passing through the National Park System. And on May 9, in honor of International Migratory Bird Day, you can bird with a ranger at Grand Teton National Park.

Ranger Andrew Langford will visit several park areas that provide the best opportunities to locate, identify, and record birds as part of the annual North American bird count and annual IMBD observance.

The bird-watching excursion begins at 8 a.m. from the Craig Thomas Discovery and Visitor Center in Moose and finishes by 4 p.m. at Christian Pond by Jackson Lake Lodge. This public activity is free and reservations are not required. Participants of the IMBD activity are reminded that park entrance stations are open; therefore a park pass is required for travel through any fee station.

Throughout the day, participants will take short walks at various locations, so those attending should wear comfortable shoes and bring a lunch, drinking water, warm clothing and rain gear. Bird field guides, binoculars and spotting scopes are also recommended items.

The 2015 IMBD theme, "Restore Habitat, Restore Birds," focuses on the loss and degradation of bird habitats around the world. Urbanization and climate change are two of the primary threats to bird populations, a park release noted. To foster conservation efforts, IMBD suggests ways to get involved in habitat restoration projects at home, in communities, and further afield. Each habitat illustrated on the 2015 IMBD poster provides a colorful view of the places migratory birds seek for nesting, wintering, or as stopover sites during migration.

Grand Teton National Park provides critical habitat for a host of migratory birds, as well as year-round species. The arrival each spring of sandhill cranes, mountain bluebirds, western tanagers, meadow larks and other charismatic and fascinating birds brings delight to park visitors and local bird watchers alike.

As always, the annual theme is relevant to host organizations and participants throughout the world. Participation in Grand Teton's IMBD tour offers a chance to learn about the benefits of birds and their unique contribution to the health and beauty of the natural areas in northwestern Wyoming.

Observed each year in May to support avian conservation, IMBD serves as the hallmark outreach event for Partners in Flight'”an international conservation program with a goal to reverse dwindling populations of migratory birds by bringing attention to factors that contribute to worldwide declines.
