A rare bat species, rarely seen in Colorado, was discovered in a Wellington yard, marking the first known sighting in northern Colorado. This evening bat, previously recorded only three times in the state, was initially mistaken for a more common species. Wildlife experts are investigating how the bat ended up in northern Colorado, with possibilities including displacement by weather or the presence of a roost in the region. The bat is small and lightweight, and is being kept warm at the wildlife center before being released back into the wild in the spring. Agencies are still working to determine where the bat should be released. This is the first known sighting of an evening bat in northern Colorado, and experts are curious to learn more about the species' presence in the region.
