    Birds can be sensitive to hot peppers. I have kept them away by boiling sliced hot peppers in water. Let this cool, and strain it into a spray bottle. Spray this once a week or so, and nothing will come near it. Just be sure not to get this in your eyes, mouth, or anywhere really.

    I recommend you contact a qualified Arborist in your area to inspect this beautiful specimen.
    A large cactus can fall without any warning if it has developed rot.
    Your County Extension Office may also have a list of specialist in your area.

    From an Arizona publication:
    Some nursery owners recommended a treatment called “digging in.’
    A spoon is used to scoop out all the black gunk until healthy flesh is reached.
    Then a mix of peroxide and water is used to sterilize the area. Next, it is dusted with sulfur, which is washed off after 10 to 15 minutes.
    The Cooperative Extension Service suggests similar treatment, except it recommends using a sterilizing mix composed of one part household bleach to nine parts water.

    This is a very severe infection. There will be no saving this one. These are very well adapted to being dry for a very long time. This is usually caused by overwatering. Usually these will not need supplemental watering at all.

    Unfortunately, overwatering needs to be mitigated, immediately, with a fungicide. If action isn't taken, you will start to notice symptoms like these.

    Leaning might be corrected by propping it with a board, or tying it up to something sturdy.

    Correcting the crack won't happen. What you will have to do, though, is to control the bacteria that will take that spot over.

    I highly suggest you contact The Desert Botanical Gardens, near the zoo. I am a horticulturist and worked their in the 90's. You don't mention what is wrong with your Saguaro, as far as what you say it is doing fine.
