Speaking of listening, I have a new list for you. Name (and describe [within reason]) ten sounds that are common in your day-to-day environment, (or night-to-night). I got the idea for this list right before the question was asked (elsewhere): 'who is the listener?' On a much more mundane level, I just thought it would be interesting to hear what other people's 'sound-scapes' are like.
For me that would be:
1) birdsong; the neighborhood is lousy with birdsong: towhees (a single sharp note, sweet & tart), california jay & crows (both raucous), seagulls (melancholy & raucous), hummingbirds (which seem to deserve a category all their own), and assorted others at different times of year
2) melodic train songs; the engineer who drives through the bay area in the evenings is particularly creative in blowing the horn, lots of notes, rhythms; we used to have a small spur line that made the most haunting sounds every evening around 7:30, but we haven't heard that for years now.
3) trucks: we seem to have a fair number of delivery trucks in the neighborhood: Fed Ex, UPS, water, and others, accelerating and braking sounds mostly
4) airplanes, both small and commercial airliners - lots of flight patterns over the bay area; we used to hear military jets before the base closures of the nineties
5) leafblowers, a recent sound and my least favorite, a weekday sound
6) pets, especially a pack of wolfhounds on the next block that howl and cry like banshees whenever their owners come home; less often, local cats fighting
7) wild animals in the neighborhood, especially raccoons (a peculiar squealing & whistling), squirrels (scrabbling & chattering), skunks (rustling), deer (hooves bumping into our fence when they jump over it at night, or lightly striking the pavement as they patrol the street)
8) buoys, out on the bay, that's a nice sound, it's a kind of distant bell; they are electronic bouys, I believe
9) buses, there is a bus that occasionally can be heard on a route about a block away - sometimes but not always
10) BART, that's our high-speed line in the bay area, and sometimes it sounds like a roller-coaster, clacking in a strange 'metallic bones' kind of way, or making the rushing sound a roller-coaster makes when it whistles down steeply. Most of the time we don't hear it at all. It's funny how that works.
11) a bonus sound: wind-chimes; they are on the next block but make a pleasant sound when the wind blows, which is frequent around here
