Amateur naturalist Mark Glenshaw continues observing the owl community in Forest Park. He watches them close enough to recognize them, name them and conduct guided tours he refers to as “owl prowls.” He conducted 90 prowls just last year.

“Each year I keep breaking my own records, but 2017 was really special,” Glenshaw said.

On December 29, Mark Glenshaw celebrated his 10th anniversary of monitoring a pair of Great Horned Owls in Forest Park. The amateur naturalist made his first appearance on “St. Louis on the Air” two years ago to introduce listeners to the pair he had dubbed Charles and Sarah. In April of this year he returned to report on the birth of the couple’s offspring, a pair of owlets whom he later named Harold and Grace. At that time he described the parents as the “Angelina Jolie and Brad Pitt” of Great Horned Owls.
