Purple Martin Gourd BirdHouse

thingiverse

This is my attempt to make the gourd type purple martin birdhouse. Using the screw and lid from thing:84 The following is from: https://www.purplemartin.org/purple-martins/history/59/tradition-shift/ Purple Martins are considered secondary cavity nesters—they do not excavate their own cavities such as woodpeckers. Instead they use cavities that are already created, either by other animals or in natural cavities of cliffs and rock formations. Traditionally Purple Martins nested in natural cavities such as old woodpecker holes, on rock ledges, or in dead trees. However, thousands of years ago, people began providing man-made housing for the Purple Martins in the form of dried, hollow gourds. Over time, the successful nesting of martins in these man-made homes, paired with the decline of natural cavities, led to a complete behavior shift within the eastern species. Lets make more homes for the Purple Martin! Starling resistant entry to spec from here: https://www.purplemartin.org/purple-martins/attracting/40/housing/ Updated 7/29/18 top vent (hanging) holes angle down to help prevent moisture entering gourd. Feedback / corrections to the model are much appreciated.
