Spring Migration Birding: Mid-Valley Hotspots

* Please note - this class meets at in the northwest corner of the Willets Whole Foods parking lot (nearest Hwy 82)  *

Migration season is an exciting time of year when many locally uncommon species can be seen while they stop to rest and refuel. This class, focused on migratory birds, will cover an overview of local migratory species, migration patterns, fascinating avian adaptations that help birds migrate, and pertinent conservation issues. We will visit several major mid-valley migration hotspots, including Crawford Ponds, Spring Park Reservoir, and other key habitat locations to be determined depending on bird activity at the time of the class. Target birds include waterfowl, shorebirds, and wading birds (Gadwall, American Wigeon, Northern Shoveler, Lesser Scaup, Grebes, Lesser and Greater Yellowlegs, Long-billed Dowitcher, Wilson's Phalarope, White-faced Ibis), as well as Osprey and other raptors, and a variety of migratory passerines. 

Birders of all experience levels welcome! Special attention will be given to orienting beginning birders to local habitats, local birds, and basic field craft skills. Mark fuller, former Independence Pass Foundation Director, and ACES Birding Guide Rebecca Weiss will be your instructors. Mark and Rebecca photographed, wrote, and published Birds of Aspen and the Roaring Fork Valley (to be released this summer!)

This class meets in the northwest corner of the parking lot at Whole Foods (nearest Hwy 82 in Wilietts) We will carpool from there to field trip locations. Come prepared for a full day in the field, including on-strenuous hiking on and off trails. Please wear layered clothing for both the chilly morning and warmer temperatures. Wear sturdy footwear, and bring rain gear, sun hat, sunglasses, sunblock, a hearty lunch, snacks, and plenty of water. Bring your binoculars (or borrow ours) and your field guide (optional). Mark and Rebecca will bring scopes, reference books, and handouts.

Mark Fuller has been a birder for 52 years and a resident of the Roaring Fork Valley for nearly that long. During his time in the valley Mark worked as the Pitkin County Environmental Coordinator and the Director of the Independence Pass Foundation and he served on the boards of several local organizations including Wilderness Workshop and the Aspen Center for Environmental Studies. Mark currently directs the Ruedi Water and Power Authority, a local intergovernmental agency concerned with water management and planning. He has taught birding classes through ACES and Colorado Mountain College and has contributed to the Colorado Breeding Bird Atlas, among other activities. Mark is the photographer of Birds of Aspen and the Roaring Fork Valley (to be released this summer!).He has birded on four continents but his favorite birding destination remains the Roaring Fork Valley and especially Independence Pass.
