Glen has been carving decorative wildfowl for over 30 years. He spends between 150 and 250 hours carving and painting each bird with intricate detail to achieve life-like accuracy.

As visual reference for his work, Glen uses photographs of each species in its natural habitat as well as taxidermy specimens. Through the relationship he has built with the ornithology department at Yale University, he borrows a specimen from the Peabody Museum of Natural History at Yale for each bird he carves.

Glen particularly enjoys working with clients who commission his work from start to finish so that they can not only choose the wildfowl, but select the way in which the head is positioned and the attitude of the bird.
