The video description says:
Come join us for the Annual Chimney Swift Watch. Watch thousands of swifts swirl in striking patterns every evening at dusk, circling together before they drop down into their chimney for the night.Read the full article
From there, we'll watch the birds circle and then go into the Tyler Building chimney that sits directly behind the parking deck at the corner of Walnut and Rankin.
This chimney is the lowest one that the birds use. It's also very close to our viewing spot on the 3rd level of the parking deck, so our swift watch should be wonderful!
These birds eat mosquitos and other insects as they fly all day, never perching. They should be here for about another week or two. Their numbers will increase daily until they leave together on their long migration to Peru, usually around October 5th-15th.
