If they can land on mu guy lines than yours is too thick
I tried a few approaches to this issue, i have tried Cable ties, they still perch on it, the only thing i found that acutally
works is this, you need a perch that is easier to land of above the anny, i have my davis and my os anny's on the mast
i ended up putting the OS above the davis and eve though the Davis is pointing north and the OS to the north west, the
birsd do not touch the davis any more, the OS is much easier for them.
If you can, buy another anny, does not have to be wired up, just needs a decent arm, i.e. a more favorable perch for them
and place it a few inches above, i will take a photo of mine in a not, the Davis still has the cable ties on it lol
