You could (if your lease or HOA / Condo Covenants & Restrictions allow it) erect a screen or enclosure on your balcony, or hang blinds or draperies. Likewise, if you own the property, you could possibly plant trees or tall hedges or erect a tall fence, within the laws and guidelines your property is subject to.
If you're looking to block them from seeing into your home through a window or glass door on your balcony, use draperies, curtains, blinds, or shutters... Or, in a pinch, cardboard, aluminum foil, or a spare blanket.
You can't legally block your neighbor's window, you can only block his view at the line of your property... Once you're out on your balcony, you're considered to be in public, and have no reasonable expectation of privacy.

What you do in your own home and how you remodel it is up to you. If you are looking to watch someone sunbathing, that would be a different story and they might be justified in getting an injunction. But they can put up a fence to block your view.
Unless the birds are causing harm to the balcony let them nest there. If their staying there is undesired wait until babies are hatched and gone then remove the nest and block where they are nesting.
Any type of curtains or shades would work. The thiner the better. You can also use window film that you can see out but neighbors canot see in. It is like car film.
Check your building / governing documents to determine the ownership of the balcony. It may be a common area, it may be a limited common area dedicated to a single unit, or it may have another ownership designation.
Glass block windows are typically installed in bathrooms. To put one in, cut out the area for block about 2.5 inches larger than the block itself. Next, nail in stop blocks along the window frame, and insert the window. Finally, inject expanding, weather proofing foam along the window's border.
Collaroo window treatments, if applied correctly, will block out roughly 99% of sun. You can never get rid of sunlight completely.
