While observing the loutish behavior of balcony sparrows, I noticed that the sun in the tropics is a late comer.
By the way does anybody really know what constitutes the tropics? I just found out myself.
The earth it seems, not only rotates around an imaginary axis at the poles, giving us a twenty-four- hour day, but it also tilts at the poles as it moves. It tilts with the equator as the axis point and this tilt give us the seasons.
Most folks believe that we have seasons because the earth moves closer and then further away from the sun as it circles the sun in its annual journey. This this is only slightly true; our seasons change because of the tilt of the earth at the equator; the equator acting as the axis point of that tilt.
As a consequence of this tilt, or as a gift, depending on your outlook, we have four seasons. That is to say, the people living in the temperate zones have four seasons. The people living in the tropics, on the other hand, experience very little change throughout the year except that the rainy seasons determine the amount of vegetation that they will have. Deciduous trees in the tropics loose their leaves in summer instead of winter, a consequence of dryness, not of a lack of sun and not a response to freezing temperatures. The dropping of leaves in the tropics is a response to a lack of moisture.
Summer in the temperate zones happens because when the earth tilts at the equator; the northern half of the earth moves closer to the sun. Temperatures warm up and the period of daylight lengthens. As an illustration of this, we can consider the zenith day. The zenith point on the earth is an imaginary lie drawn from the sun to the earth at 90 degrees. This would be a point on the earth where the sun is directly overhead at the mid day.
For the northern hemisphere the extremes of the earth's tilt and sun movement over the earth occur on December 22, the shortest day, the day with the least amount of daylight and on June 22, the day with the longest period of sunlight. The mid point of this span, March 22, is the day of the equinox. On the day of the equinox the sun is directly overhead at the equator during the mid day and the period of darkness and sunshine is nearly equal for both the northern and the southern hemisphere.
God invented things that make us happy.
Take the sparrows for instance.
Each morning they flit about my balcony and chirp happily in a little game of love.
I was born in a land to the south that is so cold that we do not have sparrows. Listening to their chirping brightens my already bright day but I was curious about all the excitement. I watched one morning in surprise as the female acted hard to get but she soon settled down, braced her legs on the balcony rail, and took on all comers. I watched the feathery little harlot and I am almost embarrassed to admit that I enjoyed spying on her depravity.
Once she had all the males excited with her flying and chirping she took a place at the balcony rail and stayed put for a good ten minutes while several males swooped in a mated with her. They just darted in, did there three or four quick jabs and darted out again. What ever happed to foreplay and afterglow?
Although I do think I saw her sporting a new gold ankle bracelet I just don't understand the males lack of sensitivity. Beyond that, how are they going to know who will help build the nest?

On June 23 the sun starts its move. It is not actually moving but the tilting of the earth makes it appear that the sun is moving. In reality the earth is rotating at the equator and tilting its northern pole closer to the sun. The zenith point changes each day and moves north. On the first of April the zenith point has moved from the equator and is over Venezuela. On May 9 it is directly overhead at Puerto Escondido in Oaxaca, Mexico, and on the 22nd of June it is overhead at Zacatecas Mexico the limit of its northern movement; it has reached the Tropic of Cancer.
Once it reaches the Tropic of Cancer, the northern limit of the tropics by the way, the sun appears to move south again. The earth has started its tilt the other way and will continue to tilt as it brings its southern hemisphere and its south pole closer to the sun and at the same time brings the start of summer in December to South America. Another of God's great inventions
The sparrows outside my window will not notice any of this because they live in the tropics and there is little change throughout the season except for a little greenery, more or less, an explosion of Jacarandas as they flower before the rainy season starts, and the onset of daily afternoon rains.
I will just continue to lounge in bed while sipping my fresh-ground Pluma Hidalgo coffee and pretending that sparrows are caring creatures. I will enjoy their musical chirping as the sun makes its daily move.
Thank God for so many great inventions.
We thank God for many gifts including electricity
