A frequent question I get is: When do I take the feeder down so the birds leave? It does not matter what You (or any human) does, it has nothing to do with the birds. If You take your feeder down, they will leave your location, but not necessarily start on the migration trip to Mexico. They go when they determine it is time to go! One group did leave here on the night of the 21 (Sept). Tonight, we will look at what the Equinox has to do with the migration in the Wikipedia excerpt (and link) below. Once again, You will find the photostudies in the G+ Albums at the links below. September 24 and 25. Enjoy!
The new albums are uploaded to G+ and ready for viewing (unlocked!). The links are below to each photostudy. Sorry some of You are having problems with the slideshows. Keep trying!
You will see more birds came in for these albums. I am preparing You now: this will be the last week of Migration Photos because they will be gone!
FAT is where its at!
|UT date and time of|
equinoxes and solstices on Earth
- Northward equinox and southward equinox: names referring to the apparent motion of the Sun at the times of the equinox. The least culturally biased terms.
- March equinox and September equinox: a usage to avoid Northern Hemisphere bias (implied by assuming that March is in the springtime and September is autumnal – true for those in the Northern Hemisphere but exactly opposite in the Southern Hemisphere).
- Vernal equinox and autumnal equinox: these classical names are direct derivatives of Latin (ver = spring and autumnus =autumn). Again, this is from a hemisphere-specific perspective of spring and fall.
- Spring equinox and fall equinox or autumn equinox: these more colloquial names are again from a hemisphere-specific perspective of spring and fall.
- Vernal point and autumnal point are the points on the celestial sphere where the Sun is located on the vernal equinox andautumnal equinox respectively (again, the seasonal attribution depends on the hemisphere).
- First point (or cusp) of Aries and first point of Libra are names formerly used by astronomers and now used by navigators andastrologers. Navigational ephemeris tables record the geographic position of the First Point of Aries as the reference for position of navigational stars. Due to the precession of the equinoxes, the astrological signs of the tropical zodiac where these equinoxes are located no longer correspond with the actual constellations once ascribed to them. The equinoxes are currently in the constellations of Pisces and Virgo. In sidereal astrology (notably Hindu astrology), by contrast, the first point of Aries remains aligned with Ras Hammel "the head of the ram", i.e. the Aries constellation.
