The Gold Finch and House Finch are very fussy about their Nesting House. Floor space must equate to 6″ x 6″‘s and the 2 inch hole needs to be 4″ above the hole at the most. I get the same exclaimation each time I show customers a Finch House. “Why does such a tiny bird have to have such a large hole?” My response is usually, “When you ask one, would you tell me.” These also should be put on a post in your yard or near buildings, just not near the feeders. They will nest in the village or in a rural area.
