Bethany Hawkwatch

Bethany's location overlooking the Minnesota River Valley affords excellent viewing opportunities for migrating birds. Over 175 bird species have been recorded on campus and raptors like eagles, falcons, hawks, and vultures migrate along the river corridor. Since 2004, when data was first collected, over 13,000 raptors have been observed passing over the Bethany campus during their fall migration. The Bethany Hawkwatch averages over 1,300 raptors each season between August 15 and December 15.

In 2010, the Bethany Hawkwatch joined Hawkcount which is a clearing house for data from across the country. That data can then be used for determining the health of raptor populations across North America. Check out the Bethany Hawkwatch website or download the 2015 Bethany Hawkwatch Report

Bird Watching Trip

In February 2016, Professor Chad Heins took students from his Avian Ecology course up to northern Minnesota in search of uncommon birds from the boreal forest and rare gulls and other birds from the Arctic. 

In the Duluth-Superior Harbor students learned to distinguish between the common Herring Gulls and the rarer Thayer’s Gull. They also compared the common overwintering Mallards with the closely related American Black Duck. Searches for wintering Gyrfalcons came up empty but students watched a Peregrine Falcon dive-bomb a Red-tailed Hawk and also found a flock of Snow Buntings in Superior. As the light faded, the class spent more time looking for Snowy Owls and managed to find two of these tundra-nesting birds before it got too dark see them.

The next day was spent in the world-famous Sax-Zim Bog northwest of Duluth. Here, boreal birds reach the southern limit of their range.  Searches for Great Gray Owl and Black-backed Woodpecker were unsuccessful but spectacular views of finches like Common Redpoll, Pine Grosbeak, and Evening Grosbeak were had at various feeding stations. Students also had a chance to observe Gray Jay, Boreal Chickadee, and Ruffed Grouse and a couple of students even tried to copy Professor Heins and have a Black-capped Chickadee eat out of their hand. Temperatures were warmer than usual and students perhaps had the most fun on a hike through a Black Spruce/Tamarack bog off of McDavitt Road.  Here they crossed paths with the tracks of a Bobcat and the ever-abundant Snowshoe Hares. A North American Porcupine snoozing in a tree though ended up being their favorite mammal of the day. 

Bethany’s small class-sizes make these types of opportunities possible. Come check us out!
