I heard that birds never fall off a branch, even if they're sleeping...?

If you did that, they'd never get up to the branch in the thirst place.

According to folk lore and old wives' tales (at least here in the South), cardinals crossing our path is good luck but when a cardinal keeps staying at your window, "attacking" himself (because he thinks it's another male threatening his territory) it means there will be a death in the household within a year.  I had one at my window for 3 months and it nearly drove us crazy.  I don't understand how he didn't batter his brains out.  Anyway, two years have passed, but no household members have passed, thank goodness.  So much for tales!

will this morning wood never deflate?

I don't think porcupines hibernate, they will use dens, and tree hollows to sleep in.  I know they can climb because I once was out hiking and found a mother and her baby up high in a tree.

Yes, Birds can cover MANY miles each and every day. When they stop to feed, drink or bathe they pad around in water. Most often nothing sticks to the birds, but there are the times that eggs and materials stick on their feet and legs. This most often happens with ducks and their webbed feet.

Depends on the bird, but they settle down about nightfall and nest in trees, buildings, rooftops, bushes, and just about any other place of saftey they can find.  They work very hard at keeping their nests concealed, making them hard to find and they are often in places away from people. With some practace and a pair of binoculars, you'd be surprized how many nests you could find though.  Especially in the spring when the birds are flying back and forth to their nests to feed their chicks!

ever seen a snake go over a branch, so yes they can.

Birds can eat all day and never get overweight.

Yes, if that is the direction they are flying. If the wind changes direction though they don't change. So not ALL the time as the question implies.

Birds make nests on the ground in low bushes and shrubs.  They benefit from the protection without hurting the shrubs and bushes

Nice question, it has been asked before. \nI'll quote myself:\n"Because of the way their legs are built.\nThe tendons in bird's legs are arranged as a pulley-rope system so that the weight of the animal pulls on these tendons and keeps their fingers closed at rest. Thus they do not require voluntary muscle action to maintain their grasp on branches.\nThis is specially characteristic of songbirds. Others may rely on nests, platforms or other types of dwellings"\nYour canary is a songbird, a member of order Passeriformes. Thus it has these specialized tendon system :-)

They must have escaped from someone - they are not native to America.  They may have been adopted by the starlings, so they will probably survive. They don't usually live in such cold climates though. Help them by feeding them through your bird feeder.  Just out of curiosity what colour are they???

They sleep in nests which are made of twigs and leaves and the interior is lined with fur, feathers or other soft material for comfort.  There are normally two exits in the nest, and they are built high in a tree between two strong branches.  They build their nests high enough to provide protection from ground predators, yet not too high or the nest will be destroyed by the winds.  Squirrels also will build a nest in a hollowed-out tree cavity.

ants do sleep, or at least have a stage where they respond noticeably worse to external stimuli and are inactive. You just don't see ants sleep because they do that in their nest, not outside. You don't see many people sleep on the streets either, do you?\nWhy we sleep is a still unsolved and very intriguing question. Especially for something that essential. Clear is that people (or animals) can even die for lack of sleep. As it is a complex subject look up more details at the link below.

Yes, unless of course the tree thinks "if nobody is going to hear me then I will fall quietly so as not to disturb the wildlife".

Birds could fly with only 1 wing if if was "falling" in one direction, if not, then it can not fly. \nHuman Nature, people always want to be better than each other

No the do not sleep. Sunnies and Northerns and perch sink near the bottom, and remain somewhat dormant. Bass may actually remain active at night and can easily be caught with floating rapalas reeled slowly across the water.\n\nTake a bright flashlight and walk along the shore shining the light into the shallows, and you will be amazed at the things you can see.
