The UW @ Bothel embraces their crow roost, which has been present since 2009. Their website states that, "the campus crows [are] a phenomenon of nature" and they report over 16,000 crows at peak winter roost numbers. People are invited to come and experience the crows at twilight. The UW has become a center for crow research.
Currently being monitored by local crow lover Cristy Berger while being hazed by Integrative Avian Solutions, as contracted by by Downtown Sacramento Partnership. Learn more at Christy's FB page. There have also been roosts documents (and studied) in nearby Woodland, Davis and Yuba City.
In 2018, we had the pleasure of visiting the Irvine roost and, over a few days, were able to observe pre-roost activities and final roost location. Like the nearby Mission Viejo Roost, the SJWS Roost starts in a more urban center and ends in a nature preserve--which lends itself to question the theory that urban roosts are "safe havens" from predators. In fact, we were fortunate enough to stumble on a Great-Horned Owl in the SJWS on an early more pilgrimage. Our count on an early November morning: 4,000. https://youtu.be/Bb7AB9VnZ-k
According to one video documentary we watched, crows have been roosting around Saddleback College since at least 1977. Currently, they pre-roost at the college and then fly into the Arroyo Trabuco Golf Course for the night. Click the photo to be connected to a 2016 video filmed by local MV birder, Kat Avila. Her recent 2018 video of an estimated 6,000 crows can be found here: https://www.youtube.com/watch?v=3h_uUeDDJN4
For decades, Lawrence, MA has hosted one of the largest winter crow roosts in New England. Both American and Fish Crows begin to form a nightly communal winter roost along the Merrimack River in October and continue through April. The estimated number of Crows last winter was well above 25,000! Learn more about this roost by visiting their Winter Crow Roost website.
In 1891, Francis Bain, a naturalist on Prince Edward Island marveled at and wrote about "...a grove in Charlottetown Park was the trysting place for central Queen's County. I have seen three thousand Crows going at sundown, on a calm autumn evening, in one, long black, silent stream of quivering pinions to this favorite resting place." Ancestors of those crows still roost in Charlottetown today. As with many an urban roost, there are mixed responses from the human co-inhabitants. Uniquely, Charlottetown has created a annual "Crow March" (parade of people dressed as crows). Here is a video of this honorific manifestation.
