Raising nest box floor to deter HOSP?

[Serena]

Hi everyone,

I ran across this today when researching the HOSP issue. Someone (not familiar with him but he is a certified agronomist/natural resources manager) reports that he has had 100% success in deterring HOSP nesting by raising the nest box floor to within 3″ of the opening. He says this prevents the HOSP from building their tall domed nest.

Obviously I can’t vouch for this, but I thought it was interesting. https://www.gettingmoreontheground.com/2023/03/06/invasive-species-spotlight-house-sparrow/

Any thoughts?

It’s not a good plan for any native species. That depth is not good. The house sparrow will reach in and pick up babies and drop them on the ground. I know from experience. I had a regular depth nest but a shallower nest would make it easier.
And that’s hard to believe. They nest in letters on signage and those have to be shallow.

Thanks for your insight; I agree it seemed too good to be true! I’m glad it’s working for him, at least. :)
