I am planning on keeping a journal of some sort this year. Just to log what all I have seen and the weather conditions that day. Right now I have down Temp, Humidity, Dew Point, Wind speed and direction, Pressure, Sunrise, and Moon Phase. Is there anything else you can think of to add???

Sounds like you have it pretty well covered. The only thing you might want to add is the time of sightings if you can remember
