To birders, “looking through the glass” refers to binoculars. Wildlife photographer Glen Apseloff, however, thinks of the phrase as referring to the windows of his house. Using a handheld camera without a flash or special filters, he has photographed enough birds from inside his house, through closed windows, to create two books. Some of the photographs and text in this slideshow can be found in his more recent book, Backyard Birds and More—Looking Through the Glass. All of the birds in this slideshow, like all of those in his books, were taken through closed windows from inside his home in a suburb of Columbus, Ohio.
He wrote each of the captions in the following slideshow.
Northern Flickers are woodpeckers and are year-round residents in Ohio. Males and females appear similar, but males have a black mustache. In Ohio, all Northern Flickers are the yellow-shafted variety; this refers to the color underneath their wings. In western states, the birds are red-shafted and males have a red mustache.The oldest Northern Flicker was a yellow-shafted male banded in Florida and later found dead there; he was at least 9 years and 2 months old.
