Starlings Breaching SREH

Sunday, March 20th, 2016

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!

100% Starling PROOF Entrance Hole?

Going from Starling Resistant to Starling Proof

The Jury Is Out

Is it really possible? I saw the ad for this entrance hole in an issue of “Feathers and Friends” and I was immediately interested. An entrance hole that touts itself as 100% starling proof is a pretty amazing discovery…if true.

As you may know, the advent of the original Starling RESISTANT Entrance Hole (SREH) by the late Charles McEwen was revolutionary for purple martin landlords. The fact that purple martins could be protected from the destructive European Starlings was a huge development. Some purple martin house manufacturers went so far as to make these SREH standard equipment on their houses and countless martins are now, for the most part, safe from these pests.

Almost immediately after the SREH was placed into use, it seems that the search for the elusive, perfect and 100% Starling Proof entrance was on. Many landlords have been actively developing different entrance shapes trying to keep out the occasional smaller sized starlings. Some folks have even hypothesized that in using SREH, that we are in essence been breeding down the size of starlings. If that happens the purple martins will have no protection from these invasive birds that are choking out our native cavity nesting birds.

The immediate benefits of SREH still outweigh any other risks involved. (Risks such as wing entrapment can be serious and deadly- read about wing entrapment HERE. Consider that European starlings are even displacing red bellied woodpeckers in order to take over the nesting cavity. Countless woodpeckers are now being forced to excavate several cavities and nest later in the season in order to deflect the pressure of the starlings. Late clutches are usually not as productive. So not only are the secondary cavity nesters in peril but the primary excavators are also at risk. Habitat loss due to urban sprawl and deforestation, in time the starlings will impact  woodpecker populations. It would seem that would decrease the amount of natural nest cavities available to secondary cavity nesters such as flycatchers, screech owls and even wood ducks, just to name a few. Human supplied bird boxes or nest boxes will become even more vital in saving our native birds. Perhaps then more emphasis be placed on active control and even local eradication of European Starlings.

Back to the question of this “100% starling proof” entrance. We will have to wait for those of you that use it to let the rest of you know. I do not have a heavy starling area but I may very well get a few of these just out of curiosity. In appearance it is very similar to the Clubhouse entrance (or Conley #2) only more narrow. The Clubhouse entrance is the SREH on the current Troyer Horizontal gourds and was named after the Purple Martin “Clubhouse” forumites that developed it.
