It would be either the rad cap, kinked hose, or vacumn leak in the tank. Is the reservoir cap on tight ? If it is not sealed air tight it will allow the vacumn to blead off and not pull fluid back to the rad as it cools.

Most likely a small leak in the tube or attachment to the tank. Allows suction to be broken as the radiators cool.

I agree. Either the return hose has a hole or is leaking somewhere. You need to find it and fix it or else it will cause your cooling system to be perpetually low on coolant, which isn't good for the cooling system or the engine.
