Angles of light...birdie woes...

Winter solstice in the northern hemisphere:

On December 21st,
Tucson's sunrise to sunset is 7:21 a.m. to 5:23 p.m.--

10 hours 2 minutes and 14 seconds of daytime,
with the sun at 34.4 degrees above the horizon.

Compare that to Seattle's 7:55 sunrise to 4:20 sunset--
just 8 hours 25 minutes of daytime(!),
with the sun at a measly 19.9 degrees above the horizon.

My childhood winters in northern Germany--8:33 sunrise and sunset at 4:22,
just 7 hrs 49 minutes of day,
with the sun barely peaking at 15 degrees above the southern horizon.

Angles of light are important--
artists speak of 'the special light in Provence'...

or 'the quality of light in Santa Fe'...
'the way the sun rains down in Tuscany' etc, etc...
it's all about geometry--

how many degrees up in the sky, how long are the shadows...

The numbers will make you crazy; they'll send you packing...

No wonder Van Gogh left the Low Countries for the South of France...

More statistics, for six months from now:
Summer solstice:
Tucson-5:18 sunrise to 7:34 sunset (standard time; AZ doesn't switch to daylight savings),
81.2 degrees in the sky, almost overhead; positively tropical.
Seattle-5:12 sunrise to 9:11 (daylight savings time), solar noon at 65.8 degrees above the horizon.

Nicaragua in December--the sun is at 54.5 degrees above the horizon...
maybe that's why León's colonial streets and its volcanic countryside looked more Tuscan in December...

Here in Tucson now--lovely morning shadows on the mountains; they really are purple on the horizons...
And just in time for winter, last week, and then again today, there has been snow on the Catalinas:


Yes, that's my work-window-view of the Catalinas, in mid-town Tucson...

...and from the entrance to Sabino Canyon, the Rincons on the east are snow-dusted as well:

This past weekend, my wife's parents were in town...so we drove up the Catalina highway; at about 7000 feet up, the icicles were impressive--there IS winter in southern Arizona; all is not cactus: ...and this is the view south, toward the Santa Rita mountains...there was snow all the way down to about 4500 feet, on the northern slopes...


...and we got down to the base of the mountains just in time for sunset: ========================

And now, for birdie woes.

Tango has been sick. Liver problems, evidently...leading to neurological issues, meaning falls and lack of equilibrium--birdie vertigo! Some trips to the vet ($$$), and now with medication and temporary cage-modifications, our Senegal parrot is improving.

I would never have guessed I would one day spend MONEY on a little birdie...(blood test? cholesterol levels?) but hey, when the little companion has a life-span of THIRTY years, you can't NOT help him out, right? (Truly, he is a feathered-friend.) A hamster or a gecko, I might just let go, you know, but a parrot?...well...It's been a dodgy few days for avian health in our household, but he's pulling through...and we can sleep more soundly...

Ay ay ay...

Winter in Tucson, then...freezing nights and snow-capped sunny afternoons, yards full of ripe citrus, an ailing parrot, and now, time off...
