This image of hundreds of Chimney Swifts, returning to their current home in the incinerator chimney at Pershing Middle School in Houston, was shot between 7:45 and 8:00 pm last night.This was shot from a tripod with a Canon EOS 5D Mark 2 at ISO 6400 and f/5.6 through a Canon 70-200mm f/2.8L IS USM lens with 2.0X teleconverter.
Hundreds of birds were moving very quickly into the top of the chimney as the final few moments of daylight rapidly faded away. This image is a layered composite of several shots of the birds, shot at shutter speeds varying from 1/60 to 1/8 sec as the light faded. That's why some of the birds show motion blur and some don't.
The Chimney Swifts will leave Houston and continue their journey South, about November 15.
