How To Make A Simple (but effective) Owl &
(by Kent Justus)
Following is a simple to make owl/crow guard made by cutting squares of the 2"x4" steel hardwire cloth to fit the front of your martin house (you will need to measure). Simply attach this square to the front of the house using plastic cable tie wraps. You can buy a bag or cannister of these at your local electrical supply store. I get mine from HQ Warehouse. - Kent

|Photo #2: Cut a section of 2"x4" steel hardwire cloth (dog fence wire) to fit the front of your martin house. Also get about 4 plastic cable tie wraps to use. These are simple to remove to conduct nest checks. Just cut them off and replace with new ones when your nest check is complete. You can buy a whole canister full of them.|

Another view. This is a very simple guard, and yet very effective to deter
predation on martins (especially nestlings) from crows and large owls.
Please do your martins a favor and attach guards to all housing to prevent
loss to these predators. Also, note the green bean stake attached to the
lower porch also with the plastic cable tie wraps. This provides extra
perching space for the martins and they love it! My martins (six pairs in
this house last year) would sit on the perches and preen in the morning.
