As the oil heats up it expands, usually not very noticeable in a car with only 4 or 5 quarts, but since we have close to 14 quarts of oil the expansion is noticeable. When the oil is cold it's thicker so it creates more pressure, as it heats it becomes thinner and so the pressure decreases. This is completely normal. You should notice similar behavior in any engine, but it will be less obvious.
Completely normal, nothing to worry about.
