We’ve been listening for YEARS now that a percentage of starlings especially in the south are breeching the Conley II Entrances. What percentage of starlings breech a Conley II? From our study sites in Pennsylvania to customers in Texas to Minnesota and everywhere in between, our estimate is 88% of European Starlings CANNOT get in a Conley II.
This STARLING STOPPER is being offered to keep the remaining approximately 12% of starlings out of gourds or houses with Troyer Tunnels...Starlings and Purple Martins VARY in size across their breeding range in North America.
STARLING STOPPERS are not recommended for people trying to get martins to breed at their location for the first time UNLESS it is a public site or site that trapping and shooting starlings is not an option. In some instances sites trying to get them for the first time could try them. Also we know of some sites that have NO martins because the starlings chased them away and hopefully with the installation of theses new Starling Stoppers will give the martins a chance to establish again.
This product is most recommended for existing Landlords having issues with starling breeching the Conley II entrance holes. States that we hear the most complaints of starling breeching; TX, OK, AR, GA, SC, NC, LA, AL, & MS. If you are from MN or WI we would not recommend this product to any one as from what we have gathered Purple Martins and starlings are larger in the Northern states.
Each Starling Stopper is screwed on to the front of the Troyer Tunnel (3 stainless screws are provided with each stopper) thus reducing the size of the entrance hole.
Once the Starling Stopper is installed (THTT) Tunnel Traps cannot be used to trap sparrows unless the Starling Stopper is removed which can be easily done by backing out the three stainless screws.
Due to limited testing at the Troyer’s two sites with over 200 pairs in 2022 we had ZERO starlings breech any of the Conley II holes. Every hole at our two sites are SREH.
