As winter wanes and the amount of daylight increases, I have been thinking about the length of my BirdCam “day”. To answer that question I ran some analysis on the corpus of data in my BirdCam logbook back to December 2007 and find that for the darker half of the year (October to March) I get approximately 2.9 fewer hours of photographic time than the length of daylight between sunrise and sunset. So for late February, at this latitude (35.8 degrees North), my expected BirdCam “day” is up to about 8 hours 20 minutes. I am losing some light because I mainly work in the back yard between my two story house on the north and a tall (80’-100’) loblolly-rich woody zone to the south. But, that’s an great improvement over the 6 hours 40 minutes I can expect for the time of the winter solstice – already 140 more minutes to photograph the birds in winter time! Just for the record, I expect to max out in June with an expected BirdCam “day” of 13 hours 20 minutes, although by then my bird traffic should be noticeably reduced.
