Starlings Breaching SREH

Most people know that Starling RESISTANT Entrance Holes (SREH) do NOT mean starling PROOF. Though uncommon, starlings have been known to occasionally breech SREH. Once a starling breeches an entrance, it is even more important to dispatch the invasive bird. The fear by most is that smaller starlings that can enter a SREH could possibly breed and create more smaller starlings, and over the course of some years with the help of natural selection, the benefits of SREH would be made obsolete. This would be as tragic and possibly as devestating for the modern day martin as bringing in these pest birds to North America in the first place.

Of course, some SREH are more restrictive that others and most breeches have been reported with the less restrictive entrances like a simple crescent or a Conley II entrance. The more restrictive, the less likely a starling can get past it. So a more restrictive SREH like an Excluder entrance would be much safer.

One well known fix for the problem of starlings getting in through a SREH, is raising the floor (or lowering the entrance) as many houses use SREH that are placed much to far up. The bottom of a Staring Resistant Entrance Hole should be flush or as close to flush as possible. The lower to the porch, the better.

Sometimes, the entrances are placed low enough, it’s just that the starlings are smaller than usual. Take the very popular Troyer Gourds. People love them. They are our best selling gourd…deep, strong, lightweight, pretty awesome really. The entrances are as low as they can go. You can modify the gourd and swap out the entrance for a more restrictive opening, trap the offending bird, or you can try this fix reported by Bradley O. on FB. We would LOVE to hear if this works or not from others who are having a problem with starling breeches in their Troyer tunneled gourds. By looking at his picture, you can see that all he did was clip 2 small binder clips on either side of the Troyer Tunnel.

Bradley states, “The clips are 1-1/2 inches “wide” (when in the position in the pic). We have done this for a few years now with no issues with martins rejecting or being injured by them. Very rarely, they push the clip open. And yes, Susan…, please spread the word! Once the starlings check out the gourds, they seem to be discouraged and we don’t see many on the gourd rack.”

We hope you all try it and let us know if it works!
