They don't need to know how to use them provided that the wings offer sufficient air resistance to make falling out of a tree survivable. The terminal velocity for a mouse is sub-lethal for instance.
Insects have been flying around for considerably longer. So even a birdbrain might spot that it was possible. And there was a lot of food on the wing and fruit up in trees once flowering plants had evolved.
If I had to guess at how flight arose in birds I would reckon that flightless birds with sinew powered legs for fighting with powerful muscles concentrated on the breast bone came first.
Powered flight becomes possible once you have the basic musculature and a lightweight framework for the limbs. Though obviously the first bird ever to do it must have been rather shocked at the time.
Flightless birds are not all sitting ducks. An ostrich can easily disembowel a man with a single leg stroke if provoked, whereas by comparison big game predators like lions are pussy cats.

Really, get a life.
The alternative (one of many) is that life originated in the air, as blobs of living cells floating, some made clever use of that air, evolved to wings, some landed and some even went for the water to live in. That makes a lot more sense from a logic POV. There is some thing abot cell membranes that would support this. And it may have originated (life) from space too. Not all lifeforms of course, some originated, well you are the expert ... ;-)

The problem with people like you, who have been brainwashed by the status quo, it that you start badmouthing anybody who comes up with ideas that threaten your hardwired rusted burned in concepts. The science is simple: A correct theory expains ALL observations. You cannot, you are just patching, distorting, and wriggling. You are, in your own words:
I assume (LOL) there is no hope at your age for rewiring.

Some time ago there was this research group who found radioative decay was influenced by the orientation of the experiment in the galactic plane, even relative to the earth rotational axis.
It was all glass. The all metal ones are terribly ineffecient at cryo temps and will quickly build up ice (from atmospheric water/ humidity). Glass is an insulator, the vacuum and silver lining help. Metal is a (heat) conductor, even with vacuum double-walls and polished insides, it's not good enough. We got our LN2 in large metal dewars, I *think* they held 60 gallons. They were set to deliver

OK, I just got some all metal 500 ml (I am just going to try a little bit) vacuum flask very cheaply. I have tested it so far with hot water, and it keeps it warm for about 12 hours. Not bad, same as the bigger glass one I have (that I used for liquid air) I think. I did read a report of metal dewars with LOX exploding due to leakage of the LOX through the walls, and then reacting with a gas reducing substance in the vacuum area (would be like what we call 'gatter' in an electron vacuum tube ?). Nothing is 100% certain, my graphics card broke down last night (on 24/7), picture all messed up this morning, things happen, using a different PC now, maybe have to buy a new one... Probabilities.

Actually, the real problem with people like this is that they aren't interested in science or electronics; they are primarily interested in themselves, and in demonstrating their mental superiority. It's their sad defense against being useless.
That's why they argue mostly off-topic stuff, in an electronics design group, and why they constantly inject personal insults into objective discussions. Now that's dumb.

You are probably referring to this work
which implicates galactic neutrinos
and this
which implicates solar neutrino's in messing up a different decay process.
You've yet to show any connection to the K-40 to Ar-40 decay used to date the dinosaur-killing asteroid, and even if this effect did impair the isotope dating process, it wouldn't destroy it's utility in establishing the sequence of events around the asteroid impact, any more than the variations in C-14 dating destroy its utility in archeology.
If everybody is using the same clock, it doesn't matter if the interval between clcok ticks isn't the same from moment to moment if the variation is the same from clock to clock.
This effect may explain why a uranium-to-lead isotope clock didn't give quite the same date for the dinosaur-killing asteroid as the regular K-40-to-Ar-40 clock.

First I am not at all sure it was an asteroid, or better THAT asteroid that killed the dinos. Some argue it was humans, as dinos were dead slow (long reaction time, seconds between a pinch in the tail and the head knowing, due to propagation speed of the nerve signals, so easy to catch or hunt in a way). They just found a skeleton with teeth marks deep into the tail. But sure an asteroid (or more than one) landed on earth, and probably caused changes, even big changes. How reliable radioactive dating is I dunno, but I would not bet on it. What I think we should do, and should have done, is look for other habitable planets with a faster than light probe. Yes and put some people in it, it is merely an engineering challenge. But instead NASA scrapped its apollos. Politics and science, to opposite forces that only seem to point in the same direction in case of total disaster or war. It was the East West tension that got US to support Von Braun to get to the moon. With that driving force gone (the tension for the politics, and the sanity and technology of Von Braun) NASA or the US space program became a social project for the technological disabled. We probably need a same sort of event or situation for the current pseudo science to be dropped and replaced with people with guts who actually DO experiments. May I recommend to you that you do some experiments, it improves on your analytical abilities and we could even see some newer electronics than Baxandal. ;-) It also makes one humble.
