An somewhat more quantitative update on the Zanesville chimney swift roost reported last week: Last night I re-visited the site I passed during a drive-by at dusk on August 20. Between 8:12 and 8:32 PM (August 28) I counted 137 chimney swifts descending into the humble chimney of the Goss Rental Center, 210 Marietta St, near the canal and river in the southern section of downtown Zanesville. This is a very unimpressive chimney only a story tall, maybe twenty feet. It sits and the northeast corner of the older red brick building of the Goss complex (consisting of several connected and disconnected buildings and additions. I haven't researched this fully, but I think this is probably an old, unlined, and long unused chimney, a vestige of a former time. There is a streetlight nearby that is taller than the chimney, and likely lights the exit/entrance with glancing light from above. I suspect that more than 137 birds are using this structure, and that the flock may build as the season progresses. I probably undercounted. Others may have entered before my arrival. I can't visit the site nightly, since it is 12 miles from our farm, and we often have other things to do at dusk. last night I arranged to have another reason to be in town. Other Muskingum County birders (or nearby) may want to pitch in to monitor this interesting site. If so, I appreciate the help. Also, I would welcome the opportunity to enjoy this phenomenon with others of like mind. Drop me a note!
