Although the rest of this posting is good and quite accurate, I think
that this statement needs to be corrected.  Lactose is not the only
nutrient in milk.  Milk (unless you drink altered products like skim
or 1% milkfat) also contains LIPID, in the form of triglyceride
droplets.  All animals can utilize this nutrient; it is, in fact, the
same thing that makes egg yolks nutritious.  Some animal milks,
particularly those of marine mammals, contain remarkable amounts of
lipid; in these instances lipid contributes well over 90% of the
nutritional value.....
  
NB - I am not saying anything about the feeding of baby birds, a topic
which I will leave to the experts on this net.  But I am merely
pointing out that blanket statements about the nutritional value of
milk based solely on the carbohydrate composition may be misleading.

Subject: Feeder Question
Date: 31 Jul 92 17:26:44 GMT
Organization: Sonoma State University


I'm looking for suggestions about our feeder.  We've had an overwhelming
number of birds at our feeder.  They go through about two pounds of seed
a day.  The problem is that they are messy eaters and much of the seed 
just falls to the ground.  So I was wondering if I should refill the
feeder everyday and let them continue to be wasteful, or to leave it
empty for a few days in the hopes that they will eat some of the seeds 
off the ground.  Right now they're not interested in the seeds on the 
ground, but it might be because they know I'll just fill the empty 
feeder back up. 

Any comments or suggestions?

Thanks,
-Bob

I have at least one pair of House Finches that tend to guzzle all
the juice out of my feeder. They perch on the glass stem of the
bottle (it's a "hover feeder" for the hummers), and flap a wing
at any hummer that tries to feed when they're perched there.

My feeder is right outside my apartment bedroom window, hanging
about one foot from the screen. I get such a closeup view of hummers

I have a hummingbird feeder up, and it seems to be quite popular.  There
are two regulars, who feel calm enough to sit with wings folded, and some
visitors that dash in and out.  Recently I noticed an interesting
behavior that I've never seen in many hours of watching hummingbirds, 
and I wondered if it is common.  When I am watering the
vegetable garden, with my finger over the end of the hose to make a
ten foot high spray or so, the hummers seem fascinated by it.  They
will come zooming in, and sit by the spray watching it.  Sometimes
they get in the way, and face it; grabbing sips on the wing?  Other
times they just hover nearby and don't seem to do anything but just
watch.  Are they drinking?  Is it the bright reflections of the drops
that attracts them, or what?  I've even had two of them sitting on the little
fence around the garden for a few minutes while I'm watering.  One
of them came over to see if my bright red chile pepper boxers might 
be a strange kind of flower, and hovered about six inches away from my
hip for a few seconds.  It certainly makes watering the garden a lot
more exciting than usual!

Recently I have noticed some male cardinals here in North Carolina
who have no feathers on their heads. In fact, I was able to watch
one go bald over the course of a couple of months. What's the deal
with this? Is it some sort of disease? A fashion statement? Male
pattern baldness? They seem perfectly healthy, and the rest of their
feathers look fine, but I'm concerned about their self-esteem. They
look like six-inch tall vultures.

pretty surprised that a hawk can be lead poisoned by ingesting lead

isn't very soluble in most acids (you've all seen the inside of

the lead is ground fairly fine, as happens in the gizzards of
waterfowl and gallinaceous birds.  Under some circumstances, evidently,
hawks are directly lead poisoned (described in the portion of

is a description.

The bird(s) were sitting on a powerline bordering a meadow when I saw them
They perched much like a Mockingbird in their stature and the way they 
help their body. The tail was what caught my eye.  It was easily 1/2 of
the overall length of the bird.  There seemed to be a notch in the tail too
Was this a swallowtail flycatcher?  I saw it from a passing car.  If it is
don't they use their tails for sudden twists and turns and stops as they`

on what basis?  A recent return trip to my home province of
Saskatchewan prompted this question.  The fact that the Krider's

known morph has made us on the Canadian prairies believe that
this is nothing but a pale morph of the subspecies that is there.
The well-known variability in Buteo plumages and the presence
of mixed pairs of the regular morph and the pale morph
further reinforce this view.  The pale morph is also less common
than the other.  What is the current prevaling view on the

As much as I hate to jump in with the rest of the Bose-bashers, I just can't
resist.

I've never really cared for the sound of a pair of Bose's.  The ad's all
proclaim revolutionary designs which are supposed to create superior
stereo imaging and subterrainian bass.  All I've ever heard is mud.

I recently purchased a pair of loudspeakers (actually my first pair of
quality speakers, I used to live with a set of Pioneer GS-201's.  Hey,
they were cheep.  Leave me alone. :-) )  I settled on Paradigm's 11se MK II.
I absolutely love them.  However, in the process of searching for them, 
I listened to the Bose 10.2's, the AM-5's, and several others.  Every  
single one of them thumped.  Literally.  Not a bit of detail in the bass
what-so-ever.  Just a relentless thwacking sound.  I really don't
want to see whats going on inside those push-pull vented bass cabinets.

Don't get me completely wrong here.  The Bose line does have its place
in audio society.  I hear they are very popular with many college students
who are looking for something that's loud, bass heavy, and that they
can beat the living $h!t out of.  (Ok, so I'm a college student too.  But
I can't live with mucked speakers...)  All the dealers tell me they
are virtually indestructable.  

Well, I've gone on long enough, and probably disturbed too many happy
Bose owners.  I apologize.  However, if you are about to go out and
buy a pair of the 2.2's, I recommend you listen to a nice pair of
Infinity reference 2's first.  Or maybe a set of Boston HD-9's.  If
you still go home with the Bose, the best I can wish you is, "Happy
thumping!"

   No comparison.  I guess I'm a planar speaker convert.  The difference
 in imaging and the dimensions of the overall soundstage of the
 Maggies burried the Vandersteins.

   No lack of dynamics as I was led to believe with the planars.
   Also, the 1.5s extend to about 35-40 Hz.  If I need that lower octave
 I can later add a sub.  Anyhow the Vanderstains do not extend more
 than a few Hz below the Mags.

   Now the real question...The list price (and selling price) where I looked
 was $1,350 for the 1.5s.  Does anyone know of a place that discounts the
 Mags.

You have a mistake somewhere in your math.
2 chan * 44100 * 16(bits)/ 8 (# bits in a byte) * 75 * 60 = 793.8 megs.
This is before you add error correction.   Well over 1 gigabyte with ECC.

A simpler way to figure out space used is to remember that stereo sound

I also recently got 10% off Vandersteen speakers, here in Raleigh, NC.  I think
that most (or at least many) dealers will give 10% discounts off of high end
components.  What you can't expect is the 30% or more discount you can find on
Sony or Pioneer components.  The most important thing is to ask for the
discount, a dealer may not offer it unless you ask.

Your class A amp should actually _cool_off_ from idle state when it

Yes it was an example, I used 5% as I know the resistors you can pick up in

I expected it to be better as it is.  5% also made my maths easier.

As I understand it (based on an article in the current issue of Audio),
the SBM technique is basically a noise-shaping technique.  It shifts the
spectrum of the quantization noise (produced during the 20->16 bit
truncation) so that it's concentrated at frequencies at which the human
ear is less sensitive.  The total amount of quantization-noise energy
isn't reduced, but its impact on our ears is.

So... if I read the description correctly, SBM is a more sophisticated
way of tackling the quantization-noise issue than a simple one-half-LSB
random dither is, but the two techniques are first cousins.

Well, it was _recorded_ with 20-bit technology, _mastered_ and
_reproduced_ with 16-bit technology, and the 20->16 conversion wasn't
a simple roundoff or truncation.
