Come on; you know we can't see it over a computer. The reservoir is the last thing I would think of if I were psychic. Many auto parts stores will rent or borrow tools. Ask for a cooling system pressure tester kit. Use that to pressurize the system, then watch where coolant is flowing from.
If the leak is very slow, you can add a small bottle of dye in the reservoir. After driving long enough for leakage to occur, you search with a black light. The dye will show up as a bright yellow stain that you can follow back to the source.
