I just "upgraded" my hummer feeder to a Humzinger 12 oz. model, as my old 8
ouncer got too shopworn.  Included in the new box were some little plastic
"bug guards" that fit over the inside of the feeding ports.  They are
allegedly to stop the bugs, but are supposed to let the tongue of the bird
be unaffected.  The hole looks pretty tight to me, but I put them on and put
out the feeder.  It seemed to me that the first visitor flitted from port to
port a bit, but seemed eventually to feed for a few seconds.  Has anybody
had any experience with these things?  Do they actually work?  Should I
remove them?  Any on or off line advice appreciated.

 

Thanks
