He loved taking pictures of birds. He had been a member of the National Audubon Society in Michigan and had acquired some interesting tools to use. He had several black nylon bird catching nets from China that were so fine that birds couldn't see them and would get caught when flying through them. I guess in China they used the birds for soup. I heard they were illegal in this country, but we used them to catch several birds and then put them in a glass cage especially made for this purpose. It could be set up with tree branches or anything you wanted and you could take pictures from inside a canvas blind set up next to it. This would help the bird to relax and act natural. He also liked to take pictures of bird's nests with the babies being fed by their parents. When I found a Black Headed Grosbeak nest in my parent's backyard, he built a wooden platform near the tree and then put a canvas blind on top of the platform. He did all this a little each day to give the birds time to acclimate to the new objects in their neighborhood. The parent birds still recognized it was a strange object and would come and go with their backs to the camera, but we did get some good pictures. One day, we caught an Oregon Junco in the captive net and in removing him, his tail feathers were pulled out. This meant he couldn't fly, so I put him in an old birdcage until his feathers grew out again. I put him in my grandma's bedroom and she enjoyed him so much we kept him over that winter. He became as tame as any hand raised bird. I took him to Echo Ridge School and put him in Dorothea Larsen's classroom for the grades one to four to enjoy for several days. They would let him out to hop along the window sill and he would go back in the cage when he was hungry. One day, he hopped outside when someone left the door open and I thought he was gone. I put the cage outside on the sidewalk anyway, and a little while later, he came hopping down the sidewalk and hopped right into the cage. Grandpa Hufnagel had extensive photography equipment. He had a Cine-Kodak special movie camera that had a time-lapse attachment. It enabled you to take a picture or frame every minute or hour or whatever you set it on. It was great to show flowers opening up or plants growing.
