SOP Bird Avoidance
I presume that you are flying a big aircraft with lots of mass and speed
At high speeds there aint much you can do in the air from the time you recognize birds until you hit one. Thankfully birds have more maneuverability. Take a look at the u-tub videos of a trainer hawk jet intersecting one.
The most effective avoidance is on the ground during taxi out. If you see birds in congregations on or near your runway, don't takeoff until they are cleared.
I'm not a fan of relying on paint schemes, radar, strobe lights or anything else not backed up by valid scientific data.
