North Campus DIY
This week I've been working with Jared Nielsen, one of the Museum's Exhibit Technicians, who also happens to be a DIY (Do it Yourself) enthusiast. With his help we've managed to build and install two nest boxes and launch our first garden surveillance balloon!
The nest boxes we chose are made of PVC and designed to be particularly appealing to certain cavity nesting birds such as Western Bluebirds, Sialia mexicana. These birds have been spotted in Exposition Park by Kimball Garrett, the Museum's resident ornithologist, and we hope they'll stick around to use our new nesting sites. The boxes are also designed to be minimally appealing to other species of birds that we don't wish to encourage, such as introduced European Starlings, Sturnus vulgaris, and House Sparrows, Passer domesticus.We ordered the boxes from the Gilbertson Nestbox Company and Jared brought all the materials necessary to assemble and install them in the North Campus. The cost for all materials including the nest box is approximately $30 each. Instructions for installation and how to properly monitor birds that move in are available on the Gilbertson website.I'll keep you posted, and let you know as soon as any birds move in. Of course Sam Easterson, our resident video naturalist is also waiting in the wings. As soon as a nest is built, he will install a video camera and we'll hopefully be able to capture images of eggs being laid and nestlings hatching!As if that wasn't exciting enough, today we launched our first garden surveillance balloon.
Our garden surveillance balloon is a project Jared discovered through the Public Laboratory for Open Technology and Science. Their Grassroots Mapping project provides instructions on how to build your own balloon mapping kit, or you can purchase a kit for $85 from their website!Jared opted for the DIY approach and sourced all of his own materials, including the 2 meter wide weather balloon and a rental helium tank! Following the Grassroots Mapping instructions, Jared rigged the balloon to carry a camera and tethered it to a 1000 foot long string which he held onto as we walked it around the site. The camera was also adapted to continually take pictures every second until our 16 megabyte memory card was full (about 2 hours). Over the next few days Jared will take all the images and stich them together using a free online software that will create an aerial map of the North Campus gardens. Not only will this map look really cool, it will also help us to keep track of all of the plants in the gardens and see how it changes over time. Yes, we are going to do this again, maybe even every few months!
